Adjusting squelch (muting)
Particularly in FM, noise can be a nuisance on a free channel. With the muting
control (SQUELCH) You can suppress this noise - but also signals which are too
weak to be received properly.
This is how to adjust the signal strength required to switch on the loudspeaker, using
the SQUELCH control knob:
The further the control knob is turned to the right, the stronger a signal has to be in
order to be audible through the loudspeaker.
In order to adjust the set to be the most sensitive to incoming signals, switch to a
free channel:
•
Use the up / down switches to find a free channel, where no signal is
displayed.
•
Then turn the SQUELCH control carefully to the right until the noise just
about disappears.
Now the loudspeaker stays off when on a free channel but it switches back on when
receiving even very faint signals.
The muting adjustment is particularly important during channel
scanning. In this mode the point to which the set is adjusted
decides whether scanning is stopped at the signal or not.
Therefore you should test the various muting settings for various
signal strengths and get to know this function.
AM / FM mode switch
In all country programming modes FM modulation (transmit and receive) is possible
on all selectable channels. AM receiving is also allowed and possible on all
channels, but AM transmission is disabled completely in 40FM mode and in the
German mode 80/12 on channels 1 to 3 and 16 to 80. In 80/12 mode You can only
transmit AM on channels 4 to 15. If You should try to transmit on a forbidden
channel in the German mode in AM, the display will blink.
Where allowed, You can switch with the AM/ FM switch between both modulation
modes.
