Power

  • Do not overload wall outlets, extension cords, or adaptors beyond their voltage and capacity. It may cause fire or electric shock.
    Refer to the power specifications section of the manual and/or the power supply label on the product for voltage and amperage information.
  • Power-supply cords should be placed so that they are not likely to be walked on or pinched by items placed upon or against them. Pay particular attention to cords at the plug end, at wall outlets, and at the point where they exit from the appliance.
  • Never insert anything metallic into the open parts of this apparatus. This may cause electric shock.
  • To avoid electric shock, never touch the inside of this apparatus. Only a qualified technician should open this apparatus.
  • Be sure to plug in the power cord until it is firmly seated. When unplugging the power cord from a wall outlet, always pull on the power cord’s plug. Never unplug it by pulling on the power cord. Do not touch the power cord with wet hands.
  • If this apparatus does not operate normally – in particular, if there are any unusual sounds or smells coming from it – unplug it immediately and contact an authorized dealer or Samsung service center.
  • To protect this apparatus from a lightning storm, or to leave it unattended and unused for a long time (especially when a kid, the elderly, or the disabled is left alone), be sure to unplug it from the wall outlet and disconnect the antenna or cable system.
    – Accumulated dust can cause an electric shock, an electric leakage, or a fire by causing the power cord to generate sparks and heat or by causing the insulation to deteriorate.
  • Use only a properly grounded plug and wall outlet.
    – An improper ground may cause electric shock or equipment damage. (Class l Equipment only.)
  • To turn off this apparatus completely, disconnect it from the wall outlet. To ensure you can unplug this apparatus quickly if necessary, make sure that the wall outlet and power plugs are readily accessible.

Installation

  • Do not place this apparatus near or over a radiator or heat register, or where it is exposed to direct sunlight.
  • Do not place vessels (vases etc.) containing water on this apparatus, as this can result in a fire or electric shock.
  • Do not expose this apparatus to rain or moisture.
  • Be sure to contact an authorized Samsung service center for information if you intend to install your TV in a location with heavy dust, high or low temperatures, high humidity, chemical substances, or where it will operate 24 hours a day such as in an airport, a train station, etc. Failure to do so may lead to serious damage to your TV.
  • Do not expose this apparatus to dripping or splashing.

Mounting the TV on a wall

warning 2

If you mount this TV on a wall, follow the instructions exactly as set out by the manufacturer. If it is not correctly mounted, the TV may slide or fall and cause serious injury to a child or adult and serious damage to the TV.

  • To order the Samsung wall mount kit, contact the Samsung service center.
  • Samsung Electronics is not responsible for any damage to the product or injury to yourself or others if you choose to install the wall mount on your own.
  • Samsung is not liable for product damage or personal injury when a non-VESA or non-specified wall mount is used or when the consumer fails to follow the product installation instructions.
  • You can install your wall mount on a solid wall perpendicular to the floor. Before attaching the wall mount to surfaces other than plaster board, contact your nearest dealer for additional information. If you install the TV on a ceiling or slanted wall, it may fall and result in severe personal injury.
  • When installing a wall mount kit, we recommend you fasten all four VESA screws.
  • If you want to install a wall mount kit that attaches to the wall using two top screws only, be sure to use a Samsung wall mount kit that supports this type of installation. (You may not be able to purchase this type of wall mount kit, depending on the geographical area.)
  • Do not mount the TV at more than a 15-degree tilt.
  • Standard dimensions for wall mount kits are shown in the table on the Quick Setup Guide.
    Do not install your wall mount kit while your TV is turned on. This may result in personal injury from electric shock.
  • Do not use screws that are longer than the standard dimension or do not comply with the VESA standard screw specifications. Screws that are too long may cause damage to the inside of the TV set.
  • For wall mounts that do not comply with the VESA standard screw specifications, the length of the screws may differ depending on the wall mount specifications.
  • Do not fasten the screws too firmly. This may damage the product or cause the product to fall, leading to personal injury. Samsung is not liable for these kinds of accidents.
  • Always have two people mount the TV onto a wall.

Providing proper ventilation for your TV
When you install your TV and One Connect Box, maintain a distance of at least 10 cm between the One Connect Box with other objects (walls, cabinet sides, etc.) to ensure proper ventilation. Failing to maintain proper ventilation may result in a fire or a problem with the product caused by an increase in its internal temperature.

  • When you install your TV with a stand or a wall mount, we strongly recommend you use parts provided by Samsung
    Electronics only. Using parts provided by another manufacturer may cause difficulties with the product or result in injury caused by the product falling.

Safety Precaution

SAMSUNG QA43LS03A 43 Inch Frame QLED 4K Smart TV - Safety Precaution
warning 2

Caution: Pulling, pushing, or climbing on the TV may cause the TV to fall. In particular, ensure your children do not hang on or destabilize the TV. This action may cause the TV to tip over, causing serious injuries or death. Follow all safety precautions provided in the Safety Flyer included with your TV. For added stability and safety, you can purchase and install the anti-fall device, referring to “Preventing the TV from falling”.
WARNING: Never place a television set in an unstable location. The television set may fall, causing serious personal injury or death. Many injuries, particularly to children, can be avoided by taking simple precautions such as:

  • Always use cabinets or stands or mounting methods recommended by Samsung.
  • Always use furniture that can safely support the television set.
  • Always ensure the television set is not overhanging the edge of the supporting furniture.
  • Always educate children about the dangers of climbing on furniture to reach the television set or its controls.
  • Always route cords and cables connected to your television so they cannot be tripped over pulled or grabbed.
  • Never place a television set in an unstable location.
  • Never place the television set on tall furniture (for example, cupboards or bookcases) without anchoring both the furniture and the television set to a suitable support.
  • Never place the television set on cloth or other materials that may be located between the television set and supporting furniture.
  • Never place items that might tempt children to climb, such as toys and remote controls, on the top of the television or furniture on which the television is placed.
    If the existing television set is going to be retained and relocated, the same considerations as above should be applied.
  • When you have to relocate or lift the TV for replacement or cleaning, be sure not to pull out the stand.
Preventing the TV from falling
SAMSUNG QA43LS03A 43 Inch Frame QLED 4K Smart TV - Preventing the TV from falling
  1. Using the appropriate screws, firmly fasten a set of brackets to the wall. Confirm that the screws are firmly attached to the wall.
    – You may need additional material such as wall anchors depending on the type of wall.
    2. Using the appropriately sized screws, firmly fasten a set of brackets to the TV.
    – For the screw specifications, refer to the standard screw part in the table on the Quick Setup Guide.
    3. Connect the brackets fixed to the TV and the brackets fixed to the wall with a durable, heavy-duty string, and then tie the string tightly.
    – Install the TV near the wall so that it does not fall backward.
    – Connect the string so that the brackets fixed to the wall are at the same height as or lower than the brackets fixed to the TV.

Precautions when installing the TV with a stand
When you install the TV with a stand, avoid placing the stand on the back part of the table surface. Failure to do so may cause the motion sensor at the bottom of the TV does not to work properly.
