On the microphone:
•

∧
or

Field intensity meter (S-meter)
On the graded bar display You can see approximately how strong the receiving signal is.
The scale under the bar display (S1 to +30) helps with orientation for an input signal in the
stages S1 to S9+30dB.
Please note: the field intensity meter only registers a signal when the muting control has
opened.
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 rotary switch or the microphone buttons 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.
