aircraft. The copilot side Audio Panel adjusts the passenger volume and squelch on the copilot’s side of the

copilot, and passengers. The small knob controls the pilot/copilot volume and squelch. The large knob
controls the passenger volume and squelch. The VOL and SQ annunciations at the bottom of the unit
indicate which function the knob is controlling. Pressing the PILOT/PASS Knob switches between volume
and squelch control as indicated by the VOL or SQ annunciation being illuminated.
