Individual RX Volume Control
Each of the COM radios (COM 1 – COM 9) has an individual

volume control knob (2)
above it.
Rotating the knob clockwise (CW) will increase the volume for that specific COM radio, and rotating it
counterclockwise (CCW) will reduce the volume.

Receiver audio select switches and associated legends
These are two blue three-position centre-off
toggle switches. When the switch is set to the

The legends may be ordered with custom
markings to match aircraft radio nomenclature.
