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 two-position switch used to select the operational mode of the unit. The selectable

positions are PIL ISO and NORMAL. These modes are described fully in sections 3.3.5.1 and 3.3.5.2

below.

3.3.5.1 NORMAL Operation

In normal use, the AA83-100 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.

3.3.5.2 PIL ISO (Pilot Isolation) Operation

In normal operation, the pilot, copilot, and passengers hear the same signals from the aircraft

communication system. Sometimes this is not desirable from the pilot's perspective, for instance during

communication with the tower on approach, or when discussions on the intercom would be a

distraction. Many times the copilot position is simply another passenger, and the pilot may wish to be

isolated from them.

PILOT ISO mode separates the pilot from the intercom network, allowing confidential radio

communications without interference from the copilot or passenger intercom or music. The pilot has no

ICS operation, and all signals are presented in mono format during this mode. All other users are

unaffected and continue to use the entertainment and intercom functions of the AA83-100.
