NOTICES TO THE USER
◆Government law prohibits the operation of unlicensed radio transmitters within the territories under
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.
Antenna substitution: Do not substitute any antenna for the one supplied or recommended by the
manufacturer or radio dealer.
You may be exposing person or persons to excess radio frequency radiation. You may contact your radio
dealer or the manufacturer for further instructions.
WARNING
Maintain a separation distance from the antenna to person(s) of at least the distance indicated in the
table below.
You, as the qualifi ed end-user of this radio device must control the exposure conditions of bystanders to
ensure the minimum separation distance (table below) is maintained between the antenna and nearby
persons for satisfying RF Exposure compliance. The operation of this transmitter must satisfy the
requirements of Occupational/Controlled Exposure Environment, for work-related use, transmit only when
person(s) are at least the minimum distance from the properly installed, externally mounted antenna.
Transmit only when people outside the vehicle are at least the recommended minimum lateral distance
away from the antenna/vehicle.

RECEIVING
Select the desired zone and channel. If signaling has been programmed on the selected channel, you will
hear a call only if the received signal matches your transceiver settings.
Receiving Group Calls (Digital)
When you receive a group call on a Conventional channel and the received group ID matches the ID set up on your
transceiver, you can hear the caller’s voice.
When you receive a group call on a Trunking channel, the transceiver automatically switches to the communications
channel to receive the call.
Receiving Individual Calls (Digital)
When you receive an individual call, a ringing tone will sound and the caller’s ID will appear on the display.
To respond to the
call, press and hold the PTT switch and speak into the transceiver as you would during a normal transmission.
