VHF DIGITAL BASE-REPEATER / UHF DIGITAL BASE-REPEATER
THANK YOU!
We are grateful you purchased this Kenwood repeater.  We
believe this easy-to-program repeater will be highly effective in
your communications system, and will keep personnel operating
at peak efficiency.
◆ This repeater is intended for use as a fixed base station with
the antenna located outdoors on the rooftop or on an antenna
tower.
u 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.

MANDATORY SAFETY INSTRUCTIONS TO INSTALLERS AND USERS
• Use only manufacturer or dealer supplied antenna.
• Antenna Minimum Safe Distance: 120 cm (4 feet), 50% duty Cycle.
• 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. 120 cm
(4 feet) , 50% duty Cycle.
• 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 fixed-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
120 cm (4 feet) , 50% duty Cycle.
You, as the qualified 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
