Receiving a signal
When the radio set is switched on, it is ready-to-receive (unless the
set is transmitting). If a signal is received on the adjusted channel,
RX
will be displayed.
Automatic squelch
Your radio set is equipped with an automatic squelch that prevents
that an annoying noise can be heard on free radio channels. However,
under certain conditions and depending on the distance - computers,
electric or electronic devices might interfere with this squelch, so that
you hear noises.
Due to the supersensitive receiver of the radio set, such interferences
in immediate proximity are normal and unavoidable. In case of such
interferences you should change the distance to the source of interfe-
rence and hold the radio set in such a manner that the antenna could
send freely.
Pilot tone process CTCSS
Your radio set is equipped with a pilot tone process that permits to
address specific individual partner stations or groups or to receive only
calls from the latter. 38 different tones are available (see table page
33
).
Note:
Make sure that you and your partner use the same channel and
the same pilot tone.
