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.Carefully remove R170, taking care not to damage board traces or adjacent components.
