RADIO SYSTEM
The radio system consists of:
•Supply cables for radio, speakers and aerial
• Radio
• Antenna located on the inside of the front fascia
• Two tweeter speakers with 6 inch (38 mm) diameter
and two mid-woofer speakers with 20 inch (130 mm)
diameter, fitted on the doors

RADIO OPERATION AND MOBILE PHONES
Under certain conditions, the mobile phone being on in
your vehicle can cause erratic or noisy performance
from your radio. This condition may be lessened or
eliminated by relocating the mobile phone antenna.
This condition is not harmful to the radio. If your radio
performance does not satisfactorily “clear” by the repo-
sitioning of the antenna, it is recommended that the
radio volume be turned down or off during mobile
phone operation.

INSTALLATION OF RADIO TRANSMITTING
EQUIPMENTSpecial 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 interfer-
ence between the communications equipment and the
vehicle’s electronic systems.
