3.3.3 VOX Operation

The VOX control is used to set the level of audio required to activate the microphones.

The AA83-001 provides three modes of intercom operation, selected by the position of the VOX control.

LIVE ICS When the VOX control is positioned fully ccw to the LIVE position, all mics will be live,

and any sound picked up will be processed by the ICS system (hot mic).

KEYED ICS When the VOX control is positioned fully cw to the MAX position, the intercom will be in a

keyed-only mode.

VOX ICS When the VOX control is positioned between fully cw and fully ccw, the intercom is in

VOX mode. To establish the VOX threshold, rotate the control ccw until the LED turns

red, and then rotate the control cw until the LED goes dark. Continue turning the control

cw until the desired voice sensitivity is set.

3.3.4 Annunciator

The front panel annunciator is a bi-colour LED that shows intercom status.

If the LED is illuminated green, it indicates transmit activity, and if it is red, it indicates VOX activity. For

transmit with sidetone or mic activity, it will illuminate amber. The green LED also indicates a possible

stuck mic if still lit after transmission is concluded.

3.3.5 MODE Control

The mode control is a three-position toggle switch used to select the operational mode of the unit. The

selectable positions are SPLIT, PIL ISO and NORMAL. These modes are described fully in sections

3.3.5.1, 3.3.5.2 and 3.3.5.3 below.

3.3.5.1 NORMAL Operation

In normal use, the AA83-001 serves as a common intercommunication system for up to four users, and a flow-

through interface for connection to the ship's external communication system. The NORM mode (default)

permits everyone on the system to talk to each other, listen to music, and hear all radio communications.

Radio transmit functions may be initiated by either the pilot or the copilot. The pilot has priority.

In NORM mode, external tie line users are included in the ICS communications.
