Note:
Make sure that the squelch function (see
3.1.20.4) is switched on.
The type of squelch function can be selected by
actuating softkeys in the squelch setting menu.
The following types of squech function are
available:
f LEV (level squelch)
f SYL (syllabic squelch)
f L+SYL (combined level and syllabic
squelch)
Level squelch works as a function of pre>
selected level of the wanted signal strength.
Only when this threshold is exceeded will the
audio signal be unmuted.
Syllabic squelch acts upon the voice part of
wanted signal. I.e. the wanted signal is checked
for voice signal parts, and only if such voice
signal parts are contained, will the audio signal
be unmuted.
