Health and safety information

Exposure to Radio Frequency (RF) Signals

Certification Information (SAR)
Your wireless phone is a radio transmitter and receiver. It is designed and manufactured not to exceed the exposure limits for radio frequency (RF) energy set by the Federal Communications Commission (FCC) of the U.S. government. These FCC exposure limits are derived from the recommendations of two expert organizations, the National  Council on Radiation Protection and Measurement (NCRP) and the Institute of Electrical and Electronics Engineers (IEEE). In both cases, the recommendations were developed by scientific and engineering experts drawn from industry, government, and academia after extensive reviews of the scientific literature related to the biological effects of RF energy. The exposure limit set by the FCC for wireless mobile phones employs a unit of measurement known as the Specific Absorption Rate (SAR). The SAR is a measure of the rate of absorption of RF energy by the human body expressed in units of watts per kilogram (W/kg). The FCC requires wireless phones to comply with a safety limit of 1.6 watts per kilogram (1.6 W/kg). The FCC exposure limit incorporates a substantial margin of safety to give additional protection to the public and to account for any variations in measurements.
SAR tests are conducted using standard operating positions accepted by the FCC with the phone transmitting at its highest certified power level in all tested frequency bands.
Although the SAR is determined at the highest certified power level, the actual SAR level of the phone while operating can be well below the maximum value. This is because the phone is designed to operate at multiple power levels so as to use only the power required to reach the network. In general, the closer you are to a wireless base station
antenna, the lower the power output.
Before a new model phone is available for sale to the public, it must be tested and certified to the FCC that it does not exceed the exposure limit established by the FCC.
Tests for each model phone are performed in positions and locations (e.g. at the ear and worn on the body) as required by the FCC.
For body-worn operations, this model phone has been tested and meets the FCC exposure guidelines when used with a Samsung accessory designated for this product or
when used with an accessory that contains no metal and that positions the handset a minimum of 1.5 cm from the body.
Non-compliance with the above restrictions may result in a violation of FCC RF exposure guidelines.
SAR information on this and other model phones can be viewed online at www.fcc.gov/oet/fccid. This site uses the phone FCC ID number A3LSMM127F.

Sometimes it may be necessary to remove the battery pack to find the number. Once you have the FCC ID number for a particular phone, follow the instructions on the website
and it should provide values for typical or maximum SAR for a particular phone.
Additional product-specific SAR information can also be obtained at www.fcc.gov/cgb/sar.

Consumer Information on Wireless Phones

The U.S. Food and Drug Administration (FDA) has published a series of Questions and Answers for consumers relating to radiofrequency (RF) exposure from wireless phones.
The FDA publication includes the following information:

What kinds of phones are the subject of this update?
The term wireless phone refers here to hand-held wireless phones with built-in antennas, often called “cell,” “mobile,” or “PCS” phones. These types of wireless phones can
expose the user to measurable radiofrequency energy (RF) because of the short distance between the phone and the user¡¯s head. These RF exposures are limited by Federal Communications Commission safety guidelines that were developed with the advice of the FDA and other federal health and safety agencies. When the phone is located at greater distances from the user, the exposure to RF is drastically lower because a person¡¯s RF exposure decreases rapidly with increasing distance from the source. The so-called ¡°cordless phones,¡± which have a base unit connected to the telephone wiring in a house, typically operate at far lower power levels and thus produce RF exposures well within the FCC¡¯s compliance limits.

Do wireless phones pose a health hazard?
The available scientific evidence does not show that any health problems are associated with using wireless phones. There is no proof, however, that wireless phones are
absolutely safe. Wireless phones emit low levels of radiofrequency energy (RF) in the microwave range while being used. They also emit very low levels of RF when in standby mode. Whereas high levels of RF can produce health effects (by heating tissue), exposure to low-level RF that does not produce heating effects causes no known adverse health effects. Many studies of low-level RF exposures have not found any biological effects. Some studies have suggested that some biological effects may occur, but such findings have not been confirmed by additional research. In some cases, other researchers have had difficulty reproducing those studies, or in determining the reasons for inconsistent results.

What is the FDA’s role concerning the safety of wireless phones?
Under the law, FDA does not review the safety of radiation-emitting consumer products such as wireless phones before they can be sold, as it does with new drugs or medical
devices. However, the agency has the authority to take action if wireless phones are shown to emit radiofrequency energy (RF) at a level that is hazardous to the user. In such a
case, FDA could require the manufacturers of wireless phones to notify users of the health hazard and to repair, replace or recall the phones so that the hazard no longer
exists.
Although the existing scientific data do not justify FDA regulatory actions, FDA has urged the wireless phone industry to take a number of steps, including the following:

  • ”Support needed research into possible biological effects of RF of the type emitted by wireless phones;
  • ”Design wireless phones in a way that minimizes any RF exposure to the user that is not necessary for device function; and
  • ”Cooperate in providing users of wireless phones with the best possible information on possible effects of wireless phone use on human health.

FDA belongs to an interagency working group of federal agencies that have responsibility for different aspects of RF safety to ensure coordinated efforts at the federal level. The following agencies belong to this working group:

  • ”National Institute for Occupational Safety and Health
  • ”Environmental Protection Agency
  • ”Federal Communications Commission
  • ”Occupational Safety and Health Administration
  • ”National Telecommunications and Information Administration

The National Institutes of Health participates in some interagency working group activities, as well.
FDA shares regulatory responsibilities for wireless phones with the Federal
Communications Commission (FCC). All phones that are sold in the United States must comply with FCC safety guidelines that limit RF exposure. FCC relies on FDA and other health agencies for safety questions about wireless phones.
FCC also regulates the base stations that the wireless phone networks rely upon. While these base stations operate at higher power than do the wireless phones themselves, the
RF exposures that people get from these base stations are typically thousands of times lower than those they can get from wireless phones. Base stations are thus not the
primary subject of the safety questions discussed in this document.

What are the results of the research done already?
The research done thus far has produced conflicting results, and many studies have suffered from flaws in their research methods. Animal experiments investigating the
effects of radiofrequency energy (RF) exposures characteristic of wireless phones have yielded conflicting results that often cannot be repeated in other laboratories. A few
animal studies, however, have suggested that low levels of RF could accelerate the development of cancer in laboratory animals. However, many of the studies that showed increased tumor development used animals that had been genetically engineered or treated with cancer-causing chemicals so as to be pre-disposed to develop cancer in absence of RF exposure. Other studies exposed the animals to RF for up to 22 hours per day. These conditions are not similar to the conditions under which people use wireless phones, so we don¡¯t know with certainty what the results of such studies mean for human health.
Three large epidemiology studies have been published since December 2000. Between them, the studies investigated any possible association between the use of wireless phones and primary brain cancer, glioma, meningioma, or acoustic neuroma, tumors of the brain or salivary gland, leukemia, or other cancers. None of the studies demonstrated the existence of any harmful health effects from wireless phones RF exposures. However, none of the studies can answer questions about long-term exposures, since the average period of phone use in these studies was around three years.

What research is needed to decide whether RF exposure from wireless phones poses a health risk?
A combination of laboratory studies and epidemiological studies of people actually using wireless phones would provide some of the data that are needed. Lifetime animal
exposure studies could be completed in a few years. However, very large numbers of animals would be needed to provide reliable proof of a cancer-promoting effect if one exists. Epidemiological studies can provide data that is directly applicable to human populations, but ten or more years¡¯ of follow-up may be needed to provide answers about
some health effects, such as cancer. This is because the interval between the time of exposure to a cancer-causing agent and the time tumors develop – if they do – maybe
many, many years. The interpretation of epidemiological studies is hampered by difficulties in measuring actual RF exposure during day-to-day use of wireless phones. Many factors affect this measurement, such as the angle at which the phone is held, or which model of phone is used.

What is FDA doing to find out more about the possible health effects of wireless phone RF?
FDA is working with the U.S. National Toxicology Program and with groups of investigators around the world to ensure that high priority animal studies are conducted to address important questions about the effects of exposure to radiofrequency energy (RF).
FDA has been a leading participant in the World Health Organization’s international Electromagnetic Fields (EMF) Project since its inception in 1996. An influential result of
this work has been the development of a detailed agenda of research needs that has driven the establishment of new research programs around the world. The Project has also helped develop a series of public information documents on EMF issues. FDA and Cellular Telecommunications & Internet Association (CTIA) have a formal Cooperative Research and Development Agreement (CRADA) to do research on wireless phone safety. FDA provides the scientific oversight, obtaining input from experts in government, industry, and academic organizations. CTIA-funded research is conducted through contracts to independent investigators. The initial research will include both laboratory studies and studies of wireless phone users. The CRADA will also include a broad assessment of additional research needs in the context of the latest research developments around the world.

What steps can I take to reduce my exposure to radiofrequency energy from my wireless phone?

If there is a risk from these products – and at this point, we do not know that there is – it is probably very small. But if you are concerned about avoiding even potential risks, you
can take a few simple steps to minimize your exposure to radiofrequency energy (RF). Since time is a key factor in how much exposure a person receives, reducing the amount
of time spent using a wireless phone will reduce RF exposure.

  • ”If you must conduct extended conversations by wireless phone every day, you could place more distance between your body and the source of the RF, since the exposure
    level drops off dramatically with distance. For example, you could use a headset and carry the wireless phone away from your body or use a wireless phone connected to a
    remote antenna.

Again, the scientific data do not demonstrate that wireless phones are harmful. But if you are concerned about the RF exposure from these products, you can use measures like
those described above to reduce your RF exposure from wireless phone use.
What about children using wireless phones?
The scientific evidence does not show a danger to users of wireless phones, including children and teenagers. If you want to take steps to lower exposure to radiofrequency
energy (RF), the measures described above would apply to children and teenagers using wireless phones. Reducing the time of wireless phone use and increasing the distance
between the user and the RF source will reduce RF exposure.
Some groups sponsored by other national governments have advised that children be discouraged from using wireless phones at all. For example, the government in the
The United Kingdom distributed leaflets containing such a recommendation in December 2000. They noted that no evidence exists that using a wireless phone causes brain
tumors or other ill effects. Their recommendation to limit wireless phone use by children was strictly precautionary; it was not based on scientific evidence that any health hazard exists.

Do hands-free kits for wireless phones reduce risks from exposure to RF emissions?
Since there are no known risks from exposure to RF emissions from wireless phones, there is no reason to believe that hands-free kits reduce risks. Hands-free kits can be
used with wireless phones for convenience and comfort. These systems reduce the absorption of RF energy in the head because the phone, which is the source of the RF emissions, will not be placed against the head. On the other hand, if the phone is mounted against the waist or other part of the body during use, then that part of the body
will absorb more RF energy. Wireless phones marketed in the U.S. are required to meet safety requirements regardless of whether they are used against the head or against the
body. Either configuration should result in compliance with the safety limit.
Do wireless phone accessories that claim to shield the head from RF radiation work?
Since there are no known risks from exposure to RF emissions from wireless phones, there is no reason to believe that accessories that claim to shield the head from those
emissions reduce risks. Some products that claim to shield the user from RF absorption use special phone cases, while others involve nothing more than a metallic accessory
attached to the phone. Studies have shown that these products generally do not work as advertised. Unlike ¡°hand-free¡± kits, this so-called ¡ °shields¡± may interfere with the proper operation of the phone. The phone may be forced to boost its power to compensate, leading to an increase in RF absorption. In February 2002, the Federal Trade Commission (FTC) charged two companies that sold devices that claimed to protect wireless phone users from radiation with making false and unsubstantiated claims. According to FTC, these defendants lacked a reasonable basis to substantiate their claim.

What about wireless phone interference with medical equipment?
Radiofrequency energy (RF) from wireless phones can interact with some electronic devices. For this reason, FDA helped develop a detailed test method to measure electromagnetic interference (EMI) of implanted cardiac pacemakers and defibrillators from wireless telephones. This test method is now part of a standard sponsored by the
Association for the Advancement of Medical Instrumentation (AAMI). The final draft, a joint effort by FDA, medical device manufacturers, and many other groups, was
completed in late 2000. This standard will allow manufacturers to ensure that cardiac pacemakers and defibrillators are safe from wireless phone EMI. FDA has tested wireless
phones and helped develop a voluntary standard sponsored by the Institute of Electrical and Electronics Engineers (IEEE). This standard specifies test methods and performance requirements for hearing aids and wireless phones so that no interference occurs when a person uses a compatible phone and a compatible hearing aid at the same time. This standard was approved by the IEEE in 2000.
FDA continues to monitor the use of wireless phones for possible interactions with other medical devices. Should harmful interference be found to occur, FDA will conduct testing to assess the interference and work to resolve the problem.
Additional information on the safety of RF exposures from various sources can be obtained from the following organizations:

Road Safety

Your wireless phone gives you the powerful ability to communicate by voice, almost anywhere, anytime. But an important responsibility accompanies the benefits of wireless
phones, one that every user must uphold.
When driving a car, driving is your first responsibility. When using your wireless phone behind the wheel of a car, practice good common sense and remember the following tips:

  1. Get to know your wireless phone and its features, such as speed dial and redial. If available, these features help you to place your call without taking your attention off the
    road.
  2. When available, use a hands-free device. If possible, add an additional layer of convenience and safety to your wireless phone with one of the many hands-free accessories available today.
  3. Position your wireless phone within easy reach. Be able to access your wireless phone without removing your eyes from the road. If you get an incoming call at an inconvenient time, let your voice mail answer it for you.
  4. Let the person you are speaking with know you are driving; if necessary, suspend the call in heavy traffic or hazardous weather conditions. Rain, sleet, snow, ice, and even heavy traffic can be hazardous.
  5. Do not take notes or look up phone numbers while driving. Jotting down a ¡°to do¡± list or flipping through your address book takes attention away from your primary
    responsibility, driving safely.
  6. Dial sensibly and assess the traffic; if possible, place calls when you are not moving or before pulling into traffic. Try to plan calls when your car will be stationary. If you need
    to make a call while moving, dial only a few numbers, check the road and your mirrors, then continue.
  7. Do not engage in stressful or emotional conversations that may be distracting. Make people you are talking with aware you are driving and suspend conversations that have
    the potential to divert your attention from the road.
  8. Use your wireless phone to call for help. Dial 9-1-1 or another local emergency number in the case of fire, traffic accident, or medical emergencies. Remember, it is a free call on your wireless phone!
  9. Use your wireless phone to help others in emergencies. If you see an auto accident, crime in progress, or other serious emergencies where lives are in danger, call 9-1-1 or
    another local emergency number, as you would want others to do for you.
  10. Call roadside assistance or a special non-emergency wireless assistance number when necessary. If you see a broken-down vehicle posing no serious hazard, a broken traffic
    signal, a minor traffic accident where no one appears injured, or a vehicle you know to be stolen, call roadside assistance or another special non-emergency number.

“The wireless industry reminds you to use your phone safely when driving.”

Operating Environment

Remember to follow any special regulations in force in any area and always switch your phone off whenever it is forbidden to use it, or when it may cause interference or danger.
When connecting the phone or any accessory to another device, read its user¡¯s guide for detailed safety instructions. Do not connect incompatible products.
As with other mobile radio transmitting equipment, users are advised that for the satisfactory operation of the equipment and for the safety of personnel, it is recommended that the equipment should only be used in the normal operating position (held to your ear with the antenna pointing over your shoulder).

Using Your Phone Near Other Electronic Devices

Most modern electronic equipment is shielded from radio frequency (RF) signals. However, certain electronic equipment may not be shielded against the RF signals from
your wireless phone. Consult the manufacturer to discuss alternatives.

Pacemakers
Pacemaker manufacturers recommend that a minimum distance of 15 cm (6 inches) be maintained between a wireless phone and a pacemaker to avoid potential interference
with the pacemaker.
These recommendations are consistent with the independent research and recommendations of Wireless Technology Research. If you have any reason to suspect that interference is taking place, switch off your phone immediately.

Persons with pacemakers:

  • should always keep the phone more than 15 cm (6 inches) from their pacemaker when the phone is switched on.
  • should not carry the phone in a breast pocket.
  • should use the ear opposite the pacemaker to minimize potential interference.
    If you have any reason to suspect that interference is taking place, switch your phone off immediately.

Hearing Aids
Some digital wireless phones may interfere with some hearing aids. In the event of such interference, you may wish to consult your hearing aid manufacturer to discuss alternatives.

Other Medical Devices
If you use any other personal medical devices, consult the manufacturer of your device to determine if it is adequately shielded from external RF energy. Your physician may be
able to assist you in obtaining this information. Switch your phone off in health care facilities when any regulations posted in these areas instruct you to do so. Hospitals or
health care facilities may be using equipment that could be sensitive to external RF energy.
Vehicles
RF signals may affect improperly installed or inadequately shielded electronic systems in motor vehicles. Check with the manufacturer or its representative regarding your vehicle. You should also consult the manufacturer of any equipment that has been added to your vehicle.

Vehicles
RF signals may affect improperly installed or inadequately shielded electronic systems in motor vehicles. Check with the manufacturer or its representative regarding your vehicle. You should also consult the manufacturer of any equipment that has been added to your vehicle.
Posted Facilities
Switch your phone off in any facility where posted notices require you to do so.
Statics Devices
When the camera is in operation, Your phone should not be near devices that produce static field.

Potentially Explosive Environments

Switch your phone off when in any area with a potentially explosive atmosphere and obey all signs and instructions. Sparks in such areas could cause an explosion or fire resulting in bodily injury or even death.
Users are advised to switch the phone off while at a refueling point (service station). Users are reminded of the need to observe restrictions on the use of radio equipment in
fuel depots (fuel storage and distribution areas), chemical plants or where blasting operations are in progress.
Areas with a potentially explosive atmosphere are often but not always clearly marked. They include the areas below decks on boats, chemical transfer or storage facilities, vehicles using liquefied petroleum gas (such as propane or butane), areas where the air contains chemicals or particles, such as grain, dust or metal powders, and any other area
where you would normally be advised to turn off your vehicle engine.

Emergency Calls

This phone, like any wireless phone, operates using radio signals, wireless and landline networks as well as user-programmed functions, which cannot guarantee connection in
all conditions. Therefore, you should never rely solely on any wireless phone for essential communications (medical emergencies, for example).
Remember, to make or receive any calls the phone must be switched on and in a service area with adequate signal strength. Emergency calls may not be possible on all wireless
phone networks or when certain network services and/or phone features are in use. Check with local service providers.
To make an emergency call:

  1. If the phone is not on, switch it on.
  2. Key in the emergency number for your present location (for example, 911 or another official emergency number). Emergency numbers vary by location.
  3. Press [SAMSUNG A3LSMM127F Galaxy M12 Dual Sim Smartphone - icon 2 ].

If certain features are in use (call barring, for example), you may first need to deactivate those features before you can make an emergency call. Consult this document and your
local cellular service provider.
When making an emergency call, remember to give all the necessary information as accurately as possible. Remember that your phone may be the only means of communication at the scene of an accident; do not cut off the call until given permission to do so.

Restricting Children¡¯s access to your Phone
Your phone is not a toy. Children should not be allowed to play with it because they could hurt themselves and others, damage the phone, or make calls that increase your phone bill.

  • For vehicles equipped with an airbag, remember that an airbag inflates with great force. Do not place objects, including both installed or portable wireless equipment in
    the area over the airbag or in the airbag deployment area. If wireless equipment is improperly installed and the airbag inflates, serious injury could result.
  • Switch off your phone before boarding an aircraft. It is dangerous and illegal to use wireless phones in an aircraft because they can interfere with the operation of the aircraft.
  • Failure to observe these instructions may lead to the suspension or denial of telephone services to the offender, or legal action, or both.

Product Performance

Getting the Most Out of Your Signal Reception
The quality of each call you make or receive depends on the signal strength in your area.
Your phone informs you of the current signal strength by displaying a number of bars next to the signal strength icon. The more bars displayed, the stronger the signal.
If you¡¯re inside a building, being near a window may give you better reception.

Understanding the Power Save Feature
If your phone is unable to find a signal after 15 minutes of searching, a Power Save feature is automatically activated. If your phone is active, it periodically rechecks service
availability or you can check it yourself by pressing any key.
Anytime the Power Save feature is activated, a message displays on the screen. When a signal is found, your phone returns to standby mode.

Maintaining Your Phone¡¯s Peak Performance
For the best care of your phone, only authorized personnel should service your phone and accessories. Faulty service may void the warranty.
There are several simple guidelines to operating your phone properly and maintaining safe, satisfactory service.

  • Hold the phone with the antenna raised, fully extended, and over your shoulder.
  • Try not to hold, bend or twist the phone¡¯s antenna.
  • Don¡¯tuses the phone if the antenna is damaged.
  • Speak directly into the phone¡¯s receiver.
  • Avoid exposing your phone and accessories to rain or liquid spills. If your phone does get wet, immediately turn the power off and remove the battery. If it is inoperable,  call Customer Care for service.

Availability of Various Features/Ring Tones

Many services and features are network dependent and may require additional subscription and/or usage charges. Not all features are available for purchase or use in all areas.  Downloadable Ring Tones may be available at an additional cost. Other conditions and restrictions may apply. See your service provider for additional information.

Battery Standby and Talk Time

Standby and talk times will vary depending on phone usage patterns and conditions.
Battery power consumption depends on factors such as network configuration, signal strength, operating temperature, features selected, frequency of calls, and voice, data,  and other application usage patterns.

Battery Precautions

  • Never use any charger or battery that is damaged in any way.
  • Use the battery only for its intended purpose.
  • If you use the phone near the network¡¯s base station, it uses less power; talk and standby time are greatly affected by the signal strength on the cellular network and the parameters set by the network operator.
  • Battery charging time depends on the remaining battery charge and the type of battery and charger used. The battery can be charged and discharged hundreds of times, but  it will gradually wear out. When the operation time (talk time and standby time) is noticeably shorter than normal, it is time to buy a new battery.
  • If left unused, a fully charged battery will discharge itself over time.
  • Use only Samsung-approved batteries and recharge your battery only with Samsung-approved chargers.
    When a charger is not in use, disconnect it from the power source.
    Do not leave the battery connected to a charger for more than a week, since overcharging may shorten its life.
  • Extreme temperatures will affect the charging capacity of your battery: it may require cooling or warming first.
  • Do not leave the battery in hot or cold places, such as in a car in summer or winter conditions, as you will reduce the capacity and lifetime of the battery. Always try to keep the battery at room temperature. A phone with a hot or cold battery may temporarily not work, even when the battery is fully charged. Li-ion batteries are particularly affected by temperatures below 0℃(32 ℉).
  • Do not short-circuit the battery. Accidental short-circuiting can occur when a metallic object (coin, clip, or pen) causes a direct connection between the + and – terminals of the battery (metal strips on the battery), for example when you carry a spare battery in a pocket or bag. Short-circuiting the terminals may damage the battery or the object causing the short-circuiting.
  • Dispose of used batteries in accordance with local regulations. In some areas, the disposal of batteries in household or business trash may be prohibited. For safe disposal options for Li-Ion batteries, contact your nearest Samsung authorized service center. Always recycle. Do not dispose of batteries in a fire.

Care and Maintenance

Your phone is a product of superior design and craftsmanship and should be treated with care. The suggestions below will help you fulfill any warranty obligations and allow  you to enjoy this product for many years.

  • Keep your phone and all its parts and accessories out of the reach of small children and pets. They may accidentally damage these things or choke on small parts.
  • Keep the phone dry. Precipitation, humidity and liquids contain minerals that will corrode electronic circuits.
  • Do not use the phone with a wet hand. Doing so may cause an electric shock to you or damage to the phone.
  • Do not use or store the phone in dusty, dirty areas, as its moving parts may be damaged.
  • Do not store the phone in hot areas. High temperatures can shorten the life of electronic devices, damage batteries, and warp or melt certain plastics.
  • Do not store the phone in cold areas. When the phone warms up to its normal operating temperature, moisture can form inside the phone, which may damage the  phone¡¯s electronic circuit boards.
  • Do not drop, knock or shake the phone. Rough handling can break internal circuit boards.
  • Do not use harsh chemicals, cleaning solvents or strong detergents to clean the phone.
    Wipe it with a soft cloth slightly dampened in a mild soap-and-water solution.
  • Do not paint the phone. Paint can clog the device¡¯s moving parts and prevent proper operation.
  • Do not put the phone in or on heating devices, such as a microwave oven, a stove or a radiator. The phone may explode when overheated.
  • When the phone or battery gets wet, the label indicating water damage inside the phone changes color. In this case, phone repairs are no longer guaranteed by the manufacturer¡¯s warranty, even if the warranty for your phone has not expired.
  • If your phone has a flash of light, do not use it too close to the eyes of people or animals.
    This may cause damage to their eyes.
  • Use only the supplied or an approved replacement antenna. Unauthorized antennas or modified accessories may damage the phone and violate regulations governing radio
    devices.
  • If the phone, battery, charger, or any accessory is not working properly, take it to your nearest qualified service facility. The personnel there will assist you, and if necessary,
    arrange for service.
