INTERCOM VOLUME AND SQUELCH
The
MAN SQ
key and
VOL/SQ
knob control the
volume and squelch of the intercom. The
MAN SQ
key
allows either automatic or manual control of the squelch
setting. The
VOL/SQ
knob controls volume or manual
squelch adjustment for the pilot and copilot/passenger.
When the MAN SQ annunciator is not lit (auto-squelch
is on), the
VOL/SQ
knob controls only the volume.
When the MAN SQ annunciator is lit (manual squelch),
the
VOL/SQ
knob controls both volume and squelch.

Intercom Volume Control
The intercom volume is controlled with the
VOL/
SQ
knob. The small knob controls the pilot volume.
The large knob controls the copilot/passenger volume.
Turning the knob clockwise increases volume, turning
counterclockwise decreases volume. When squelch is
automatic (MAN SQ annunciator is not lit) and the VOL
annunciator at the bottom of the unit is lit, intercom
volume may be adjusted.
NOTE:
When the
MAN SQ
key is not lit (auto-
squelch is active), pressing the
VOL/SQ
knob has
no effect on the VOL/SQ selection.
Intercom Manual Squelch Control
The intercom squelch function has the ability to quiet
the ambient cockpit noise when no person is talking. Each
microphone input has an automatic squelch threshold.
Manual squelch adjustment is also available if desired.
Pressing the
MAN SQ
key toggles between the
automatic and manual squelch mode. When in manual
squelch, the MAN SQ annunciator is lit.
In manual squelch mode the
VOL/SQ
knob adjusts
either the volume or squelch threshold level.
Pressing the
VOL/SQ
knob toggles between volume
and squelch adjustment. The annunciator at the bottom of
the unit indicates which function the knob is controlling.
In manual squelch mode, the small
VOL/SQ
knob
controls pilot squelch threshold. The large
VOL/SQ
knob controls copilot/passenger squelch threshold.
Turning either knob clockwise increases squelch level,
counterclockwise decreases squelch level.
MASTER AVIONICS SQUELCH (MASQ)
MASQ (Master Avionics Squelch) reduces ambient
noise from the aircraft radios. When no audio is
detected, MASQ processing further reduces the amount of
background noise from the radios.
