2.4.2 ACCESSORY PIGTAIL INSTALLATION
1. Remove the bottom cover of the transceiver to 
access the audio/logic board.
2. Plug the pigtail cable from the kit into J101 as 
shown in Figure 2-3. The plug can be inserted only 
one way.
3. Position the strain relief in the external speaker jack 
slot of the chassis (see Figure 2-3)
4. If installing the ignition sense function, proceed to 
the next section to remove R170. Otherwise, 
reinstall the bottom cover.
2.4.3 CONNECTING IGNITION SENSE WIRE
NOTE: If the ignition sense function is not used, no 
transceiver modifications are required and this 
section can be skipped. However, then be sure that the 
Ignition Sense Delay Time is set to “Forever/Infinite”. 
If it is not, improper transceiver operation may result 
when starting the vehicle.
General
When the ignition sense line is connected, the 
following additional functions are provided:
The transceiver turns on and off with the vehicle 
ignition switch (if the front panel power switch is 
on).
The horn alert (LTR-Net/Multi-Net) may be auto-
matically disabled when the ignition switch is on.
A transceiver power turn-off delay can be 
programmed. Standby current (receive mode, audio 
squelched) is about 1 ampere.
With LTR-Net models, the de-registration message 
is sent and settings saved (see NOTE on page 2-3).
Removing R170
When the ignition sense function is used, resistor 
R170 on the audio/logic board must be removed. The 
general location of this resistor is shown in Figure 2-3, 
and the exact location is shown in Figure 2-5. Care-
fully remove R170, taking care not to damage board 
traces or adjacent components.
