CONFIDENTIAL AND PROPRIETARY TO ANODYNE ELECTRONICS MANUFACTURING CORP.

While in PILOT ISO mode, the pilot maintains complete control of all the radio functions of the

intercom, and the pilot mic and TX keyline are directly connected to the transceiver. The copilot and

passengers will be unable to monitor any transceiver activity, although they retain full ICS and music

functions.

This mode is 'fail-passive', meaning that it requires no power to operate and is the same mode the box

goes into automatically when power is lost to the AA83-100. In this way, switch over is immediate

for the pilot and there is no possibility of lost communication because of a lack of pilot action. Note that

the pilot's boom mic is sent directly to the radio in this mode, and only a PTT key input is needed to

transmit.

Note: In this mode, the receive/sidetone levels may require adjustment at the audio source.

3.3.6 Radio Functions

There are two PTT inputs: one each for the pilot and co-pilot. Activation of either PTT input connects

the user’s MIC to the radio, and activates the output PTT to the radio. Sidetone is provided fr om the

radio, not by the AA83-100.

Note: A priority transmission feature allows the pilot to override the copilot.

3.3.7 Muting Logic

When transmitting, any music will be muted quickly, and will slowly return when transmission is

completed. Music will also be muted when ICS or RX functions are active. The degree of muting is set

at the time of installation. The relative volume of the music can be changed from the front panel by the

knob marked with a musical note.

Below is a simple chart to aid in understanding audio switching in the NORMAL Operation mode.

The following terms are used:

'Active' - Function being used.

'Muted' - Functions that are overridden by the active condition.

'Idle' - Functions that are not active, but still available for use.
