ICS VOL/PILOT VOX

This control is a fluted concentric rubber knob on the top of the panel.

The inner (front) knob is the ICS VOL control, which is used to set intercom volume. It is at minimum

volume when fully counterclockwise (ccw). As the knob is rotated clockwise (cw), the ICS volume

for the crew increases. The ICS is muted during transmit operations.

The outer (rear) knob is the PILOT VOX control, that controls VOX for the pilot only. For full

information on VOX operation, see section 910.7.2 below.

MUSIC VOL/COPILOT VOX

This control is a fluted concentric rubber knob on the bottom of the panel.

The inner (front) knob is the MUSIC VOL control, which is used to set normal music volume. The

volume can be adjusted from minimum (fully ccw) to maximum (fully cw).

The outer (rear) knob is the COPILOT VOX control, that controls VOX for the copilot and

passengers. For full information on VOX operation, see section 910.7.2 below.

ANNUNCIATOR

The 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.

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

section 910.7.2 below.

PTT SWITCHES

PTT Switches are installed on the control sticks. They are used for radio transmittions. Further

PTT switches are installed on the power levers and are used for the intercom.

SOCKETS

Dual sockets for connecting the headsets are installed on the right side of each seat. The aft

cockpit also features a receptacle for music input.
