NOTE: With squelch and tone squelch the audio output is activate when:

MCR41-MCR42 User Manual
MCR42 is able to detect a digital tone squelch generated
by a Wisycom transmitters (ex. MTH400/MTH300/MTP40/
MTP30).
Tone squelch ON: when the tone squelch is enabled the
audio is muted unless the correct carrier is detected. Tone
squelch allows to work with lower RF squelch, increasing
the coverage and the robustness especially in presence of
digital television carriers (DVB-T).
Tone squelch ADVanced: when tone squelch is in
advanced mode the receiver processes also PTT data (push
to talk): activating the command audio output when the
button is pressed on remote transmitter.
When tone squelch is off it is possible to choose where to
put the output between LINE and COM.
The COM column is present only using the Stand alone
socket BPA42-PTT
When tone squelch is set to ON it is possible to choose

Usually Line is always ticked and Com (PTT) is ticked on
"PTT push." as additional return channel (intercom).
The COM column is present only using the
