ATR833 / P/N 833-(1xx)-(1xx)
Operation and Installation
2.4.1 VOL – Volume
Normally (not necessarily selected with the
button) with the rotation
of the
key, the reception volume can be adjusted.
Range: 01 - 16
The VOL-Setting does only affect the received signal, not the
Intercom level, which is pre-configured by factory.
2.4.2 SQ – Squelch
By pressing the
key once, with the help of the
rotary knob
Squelch can be adjusted.
Range: 01 - 10
The setting for the Squelch is dependent on different factors. For motor
aircrafts an initial setting of 7-8 applies, gliders may use settings below
that value. A high number reflects a high input sensitivity and may result
in disturbances from different sources (engine, strobe lights).
The default Squelch setting is 07 ... 08. Higher values could
suppress weak signals. Squelch does not impact the
Intercom.
