The optional external speaker includes a trunnion bracket that permits the

speaker to be mounted in a variety of configurations (see Figure 9).

dashboard or other accessible areas, while permitting the speaker to be

tilted to a desired angle.

1. Using the trunnion bracket as a template, drill the necessary mounting

holes and secure the bracket with the self-tapping screws provided.

2. Position the external speaker onto the trunnion bracket, and secure it

using the wing screws provided.

LED Surveillance Configuration (Option Wiring – User

Configurable)

The APX VA's LED indicator can be disabled for night use or surveillance

operations by using the following optional wiring connections (refer to the

Speaker and Interface Connector (J1) from Figure 7 and Figure 10).

•

The LED indicator can be disabled by adding a jumper wire between J1

Connector Pin 17 (SURV) to Pin 14 (GND); this solution supports ONLY

LED OFF Configuration; this would disable ALL LEDs including the

Purple LED.

•

The LED Indicator can be selectably disabled by installing a wired toggle

switch (not provided) between J1 Connector Pin 17 (SURV) to Pin 14

(GND); this solution allows all use to readily enable or disable LED

Surveillance Mode. In the LED Surveillance Mode, ALL LED indications

are disabled, including error indications.

Note: If the switch option is chosen, a switch change only takes effect when

the radio is inserted.
