government control.
◆Illegal operation is punishable by fi ne and/or imprisonment.
◆Refer service to qualifi ed technicians only.
Safety: 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 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 somebody is either standing near to or touching the antenna,
to avoid the possibility of radio frequency burns or related physical injury.
◆DYNAMITE BLASTING CAPS
Operating the transceiver within 500 feet (150 m) of dynamite blasting caps may cause them to
explode. Turn OFF 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 sure they are carried in a closed metal box with a padded interior. Do not transmit while
the caps are being placed into or removed from the container.

MANDATORY SAFETY INSTRUCTIONS TO INSTALLERS AND USERS
• Use only manufacturer or dealer supplied antenna.
• Antenna Minimum Safe Distance: Refer to the values in the table below.
• Antenna Gain: 0 dBd referenced to a dipole.
The Federal Communications Commission has adopted a safety standard for human exposure to RF (Radio
Frequency) energy which is below the OSHA (Occupational Safety and Health Act) limits.
• Antenna Mounting: The antenna supplied by the manufacturer or radio dealer must not be mounted
at a location such that during radio transmission, any person or persons can come closer than the
minimum safe distance indicated in the table below.
• To comply with current FCC RF Exposure limits, the antenna must be installed at or exceeding
the minimum safe distance shown above, and in accordance with the requirements of the antenna
manufacturer or supplier.
• Vehicle installation: The antenna can be mounted at the center of a vehicle metal roof or trunk lid, if
the minimum safe distance is observed.
• Base Station Installation: The antenna should be fi xed-mounted on an outdoor permanent structure.
RF Exposure compliance must be addressed at the time of installation.
