How does the Reverse action work?
When the reverse action is selected for either the tone
squelch, “tSqL-r,” or DTCS squelch, “dtCS-r,” and a signal
with the matched tone (or DTCS) is received, the squelch
closes, and the receiver mutes the signal. You can listen to
signals with any tone other than the specified one.
