◆ This repeater is intended for use as a fixed base station with
the antenna located outdoors on the rooftop or on an antenna
tower. (except USA and Canada)
◆ This repeater is designed for a 13.8 V DC power source!
Never use a 24 V DC or higher source to power the repeater.
◆ Use only the supplied DC cord.
◆ Do not remove the ferrite core attached to the DC cord. Doing
so may cause interference with radio communications.

by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment to an outlet on a circuit different from that to
which the receiver is connected.
• Consult the dealer for technical assistance.

REPEATER OPERATION
Note: Please consult your dealer for programming the repeater. Due
to the frequency stability on the 6.25 kHz bandwidth channel, when
operating the repeater using an optional OCXO unit, allow the unit to
warm up for 24 hours after turning the power on.
After turning on the power, wait for approximately 10 seconds for
the VCXO or 5 minutes for the OCXO (when mounting) to warm up.
During this time, the CH/STATUS Display will blink. The keys will
function when they are pressed.
When power is applied to the unit, the POWER indicator lights
green. Turn the VOLUME control clockwise until a click sounds,
to unmute the audio. Rotate to adjust the audio. Turn the
VOLUME control counterclockwise fully to mute the audio.
The BUSY indicator lights green while receiving a signal and the
TX indicator lights red while transmitting.

MANDATORY SAFETY INSTRUCTIONS TO INSTALLERS AND USERS
• Use only manufacturer or dealer supplied antennas.
• Antenna Minimum Safe Distance: 30 cm (1 foot).
• 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 above indicated minimum safe
distance to the antenna, i.e. 30 cm (1 foot).
• 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 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.
Maintain a separation distance from the antenna to person(s) of at least 30 cm (1 foot).
You, as the qualied end-user of this radio device must control the exposure
conditions of bystanders to ensure the minimum separation distance (above) 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.
