NOTICES TO THE USER
◆ Government law prohibits the operation of unlicensed radio
transmitters within the territories under government control.
◆ Illegal operation is punishable by ne and/or imprisonment.
◆ Refer service to qualied technicians only.
◆ This repeater is intended for use as a xed base station with
the antenna located outdoors on the rooftop or on an antenna
tower. (except U.S.A. and Canada)
◆ This repeater is designed for a 13.2 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.

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: 180 cm (6 feet).
• 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. 180 cm (6 feet).
• 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 180 cm (6 feet).
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.
