Safety & Warnings
It is important that the operator is aware of and understands hazards common to the operation of any transceiver.
WARNING!
– EXPLOSIVE ATMOSPHERES (GASES, DUST, FUMES, etc.): Turn off and do not operate your transceiver while taking on fuel, or while parked in gasoline service stations. Do not carry spare fuel containers in the trunk of your vehicle if your transceiver is mounted in the trunk area.
– INJURY FROM RADIO FREQUENCY TRANSMISSIONS: Do not operate your transceiver when anyone is touching the antenna, or when anyone is standing within two to three feet of your antenna, to avoid the possibility of radio frequency burns or related physical injury.
– DYNAMITE BLASTING CAPS: Dynamite blasting caps may explode by the operation of transceivers if such operation occurs within 500 feet of the blasting caps. Turn off and do not operate your transceiver when in an area where blasting is in progress, or where “TURN OFF TWO-WAY RADIO” signs have been posted. If you are transporting blasting caps in your vehicle, make certain they are carried in a closed metal box having a padded interior. Do not transmit during the time that caps are being placed into or removed from this container.
WARNING! INTERFERENCE WITH VEHICULAR ELECTRONICS
Electronic fuel injection systems, electronic anti-skid braking systems, and electronic cruise control systems are typical of the types of electronic devices that may malfunction due to a lack of protection from radio frequency energy that is present when transmitting. If the vehicle contains such equipment, consult the vehicle manufacturer or dealer to determine if such equipment is adequately shielded from radio frequency energy.
