INSTALLATION OF RADIO TRANSMITTING
EQUIPMENT
Special design considerations are incorporated into this
vehicle’s electronic system to provide immunity to radio
frequency signals. Mobile two-way radios and telephone
equipment must be installed properly by trained person-
nel. The following must be observed during installation.
The positive power connection should be made
directly to the battery and fused as close to the battery as
possible. The negative power connection should be made
to body sheet metal adjacent to the negative battery
connection. This connection should not be fused.
Antennas for two-way radios should be mounted on
the roof or the rear area of the vehicle. Care should be
used in mounting antennas with magnet bases. Magnets
may affect the accuracy or operation of the compass on
vehicles so equipped.
The antenna cable should be as short as practical and
routed away from the vehicle wiring when possible. Use
only fully shielded coaxial cable.
Carefully match the antenna and cable to the radio to
ensure a low Standing Wave Ratio (SWR). Mobile radio equipment with output power greater than
normal may require special precautions.
All installations should be checked for possible

interference between the communications equipment
and the vehicle’s electronic systems.
Operating, servicing and maintain -
ing a passenger vehicle or off-highway
motor vehicle can expose you to chemicals
including engine exhaust, carbon monox -
ide, phthalates, and lead, which are known
to the State of California to cause cancer and
birth defects or other reproductive harm.
To minimize exposure, avoid breathing
exhaust, do not idle the engine except as
necessary, service your vehicle in a
well-ventilated area and wear gloves or
wash your hands frequently when servicing
your vehicle. For more information go to
www.P65Warnings.ca.gov/passenger-vehicle .
