Intercom Squelch Level Adjustment
The Intercom Squelch Level Adjustment pages are
used to display and adjust the Intercom Squelch level
to match the sensitivity for your system and personal
needs. You may set the levels individually for Mic 1
and Mic 2. The range is from 0 to 127, with the higher
number being more sensitive. A low value allows
more noise/sound through the intercom to allow for
speaking when there is more noise in the background.
A higher value reduces noise/sound allowed through
the intercom.
1. In the Comm Radio Information function, turn the
LARGE knob to each Intercom Squelch Level page.
