6.4 Interference suppression
The interference suppression will mute the receiver
in speech / music pauses when interfering signals
are received and the levels of these signals are
below an adjustable threshold value. A high thresh-
old value, however, will also reduce the transmis-
sion range as the receiver will also be muted if the
power of the radio signal falls below the threshold
value adjusted. Therefore, adjust a high threshold
value when the reception is good and a low value
when there is a great distance between the trans-
mitter and the receiver.
1) Call up the setting for interference suppression
via the menu item
Squelch
of the main menu.
Fig. 21
2) Turn the knob PUSH
/
CONTROL to set the
threshold value:
0 = standard setting
1 …. +10 in case of good reception
-1 … -5 in case of great distance
3) Press the button SETUP to save the setting.
