MOBILE INSTALLATION
ANTENNA CONNECTION
Before operating mobile, you must first install an
efficient, well-tuned antenna. The success of your
mobile installation will depend largely on the type of
antenna and its correct installation. The radiotelephone
can give excellent results if the antenna system and its
installation is given careful attention.
DC POWER CABLE CONNECTION
To prevent the risk of short circuits, disconnect other
wiring from the negative (-) battery terminal before
connecting the radiotelephone. Confirm the correct
polarity of the connections before attaching the power
cable; red connects to the positive (+) terminal, black
connects to the negative (-) terminal. Use the full
length of the cable without cutting off excess even if the
cable is longer than required. !n particular, never

remove the fuse holders from the cable. After
completing radiotelephone connections to the battery,
then reconnect any wiring removed from the negative
terminal.
If the power cable must be routed through a hole in the
vehicle chassis or body, for example in the firewall at the
front of the passenger compartment, use a rubber
grommet to protect the cable from abrasion. The entire
length of the cable must be dressed so it is isolated from
heat and moisture. After the cable is in place, wind
heat-resistant tape around the fuse holder to protect it
from moisture. Tie down the full run of cable.
The vehicle battery must have a nominal rating of 12 V.
Never connect the radiotelephone to a 24 V battery. Be
sure to use a 12 V vehicle battery that has sufficient
current capacity. If the current to the radiotelephone is
insufficient, the Display may darken during transmission,
or transmit output power may drop excessively.
Only after completing the installation, connect the
radiotelephone's power supply connector to the DC
power cable. Press the connectors firmly together until
the locking tab clicks.
Note:
If you use the radiotelephone for a long period when the
vehicle battery is not fully charged, or when the engine is OFF, the
battery may become discharged, and will not have sufficient reserves
to start the vehicle. Avoid using the radiotelephone under these
conditions.
@ Replacing Fuses
If the fuse blows, determine the cause then correct
the problem. Refer to additional information
including fuse ratings on page 2.
CAUTION:
Replace blown fuses only after investigating and
correcting the cause of the failed fuse. Always replace a blown
fuse by a new fuse with the specified ratings.
GROUND CONNECTION
For a mobile installation, it is extremely important to
securely connect a low-resistance ground strap from the
radiotelephone GND terminal to the metal vehicle
chassis. This connection is necessary since mobile
antennas are physically small and, therefore, less
efficient than larger base station antennas. If a strap is
not available, a large gauge copper wire is suitable.
Always clean paint or dirt from the vehicle connection
point and expose bare metal before connecting the
ground. A high-quality ground installation significantly
improves the performance of a mobile antenna.
