3.3 Controls and Indicators
3.3.1 ICS VOL/VOX
The ICS VOL/PILOT VOX control is a fluted concentric rubber knob on the left side of the front panel.
The inner (front) knob is the ICS VOL control, which is used to set Intercom volume. It is at minimum volume
when fully counter-clockwise (ccw). As the knob is rotated clockwise (cw), the ICS volume for crew and
PAX increases. The ICS is muted during transmit operations.
The outer (rear) knob is the PILOT VOX control. For full information on VOX operation, see section 3.3.4.
3.3.2 MUSIC VOL/COPILOT VOX
The MUSIC VOL control is a fluted concentric rubber knob on the right side of the front panel.
The inner (front) knob is the MUSIC VOL control, which is used to set normal music volume. The volume is
at minimum when fully counter-clockwise (ccw), and as the knob is rotated clockwise (cw), the volume
increases. Music is muted during transmit operations.
The outer (rear) knob is the COPILOT VOX control. For full information on VOX operation, see section
3.3.4.
3.3.3 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.
