Best Practices: Installation & Troubleshooting 4-3
4.4 Jump-Start the Vehicle
The state of your radio prior to needing a jump-start may be unknown, and the radio may attempt to
return to its last state (radio ON), when doing a jump-start. Therefore, Motorola recommends the
following steps be taken before jump-starting any vehicle containing a radio.
1. Locate the ignition sense line and the main power leads (thick red wire) near the battery
positive terminal.
NOTE: These lines are fused. In the event these lines are not fused (add the appropriate fuse in line)
use whatever tools necessary to physically disconnect the ignition sense and power lines
from the battery terminal.
2. Open up the fuse holders and remove the fuses out of the kits.
3. Re-tighten the fuse holders but without the fuses to insure that ignition sense and power lines
do not interfere with any moving parts.
4. Proceed with the jump-start routine as described by your vehicle owner’s manual.
5. Once the jump-start process is complete, re-install the fuses into their holders.
4.5 Eliminate Noise/Howling from PA Speaker
1. Refer to Section 2.1.2 for recommended methods of installation available for the mobile
two-way radio, with accessories placed to the vehicle as desired.
2. Refer to Figure 2-2 for the wiring diagrams for the recommended configurations.
Do not jump-start vehicle with radio power or ignition sense cables connected.
Damage to the radio and/or accessories may result.
