◆This repeater is intended for use as a fixed base station with
the antenna located outdoors on the rooftop or on an antenna
tower.
◆This repeater is designed for a 13.6 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.

FCC WARNING
This equipment generates or uses radio frequency energy. Changes
or modifications to this equipment may cause harmful interference
unless the modifications are expressly approved by the party
responsible/JVC KENWOOD. The user could lose the authority to
operate this equipment if an unauthorized change or modification is
made.
INFORMATION TO THE DIGITAL DEVICE USER REQUIRED BY
THE FCC
This equipment has been tested and found to comply with the limits
for a Class B digital device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against
harmful interference in a residential installation.
This equipment generates, uses and can generate radio frequency
energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications.
However, there is no guarantee that the interference will not occur
in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined
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 after turning the power on. Refer to the KXK-3
instruction manual concerning the warm up duration.
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 qualied 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.
