2.4 Ignition Cable
Motorola supplies an ignition sense cable and recommends that it be used with every mobile
installation. The ignition sense cable allows the radio to be turned on and off with the vehicle ignition
switch, and allows the radio to “remember” the state of the radio on/off switch, even if it is changed
while the vehicle is off.
• For radio ON/OFF control independent of the ignition switch, connect the red ignition cable
(orange for remote) (pin 25 of accessory connector) to “battery hot” at the vehicle fuse block.
• For radio ON/OFF control via the ignition switch, connect the red ignition cable (orange for
remote) to “ignition” at the fuse block.
Note that for remote mount installations, the green and orange leads are connected, not the red lead
from the rear of the radio. See
Table 2-1.
The ignition sense cable uses either a 3-amp (P/N 6580283E01) or 4-amp (P/N 6580283E02) fuse.
For other considerations when connecting the ignition cable, see the XTL 5000 Basic Service
Manual (Motorola publication part number 6881096C73).
2.5 Antenna Installation
IMPORTANT NOTE: To assure optimum performance and compliance with RF Energy Safety
standards, these antenna installation guidelines and instructions are
limited to metal-body vehicles with appropriate ground planes and take
into account the potential exposure of back seat passengers and
bystanders outside the vehicle.
NOTE: For mobile radios with rated power of 7 watts or less, the only installation restrictions are to
use only Motorola approved antennas and install the antenna externally on metal body
vehicles. For mobile radios with rated power greater than 7 Watts, always adhere to all the
guidelines and restrictions in section 2.5.1 below.

COMPARTMENT
A good chassis connection via the black primary
power cable is essential for radio operation and
to prevent damage to the radio and cable kit.
Connection to the vehicle frame is desirable.

SEE NOTE
NOTE:
Caution: if you choose to connect the radio’s IGNITION line directly to the car’s battery, excess use of the radio when the car’s ignition is not running (i.e. alternator running)
could result in a slow discharge of the car’s battery. This configuration allows the radio to operate with the car’s ignition switch ON or OFF.
If the radio’s IGNITION line is wired to the car’s ignition switch, the radio will only function when the car’s ignition switch is turned ON.
