Chapter 4 Options and Accessories Installation

4.1

Dash-Mount Accessory Installation

NOTE: This configuration is not applicable for 100W radios.
For dash-mounted configurations, the accessories must be installed through the accessory
connector assembly that is located on the rear of the radio, adjacent to the power connector.
Motorola-approved accessories are supplied with male terminals crimped to a 20-gauge wire
specifically designed to fit the plug of the accessory connector assembly.
Insert the male terminal into the accessory connector assembly in the appropriate location and
connect the accessory connector assembly in the rear accessory port. Do not use other generic
terminals in the plug. Generic terminals can cause electrical intermittencies and may cause damage
to the plug.
4.1.1

Dash-Mount Emergency Pushbutton or Footswitch Installation

Mount the footswitch using the hardware that comes with the kit. Open the accessory cable
connector housing; remove the jumper wire. Connect the emergency switch wires to pins 14 and 15
(see Figure 4-1). Close the connector housing; route the finished cable from the switch location to
the control head location.
NOTE: The emergency footswitch should be attached with A+ unattached.
A+ should be attached after successfully securing the screws in the connector.
The radio is sold with correct accessory cables and jumpers in order to have emergency
! de-activated by default, regardless of the setting in CPS. However, if cables are not used, or if
jumpers are removed without replacing with an emergency accessory button/switch at one of
the accessory ports, the radio will power-up upon the application of A+. The display may not
C a u t i o n
show an indication that the radio is on, and this can result in an incorrect operation of the radio
as well as excessive current drain of the vehicle's battery when the engine is off.
