9951 Scan/sweep-stop signal level
When the receiver detects a signal whose level is stronger than the preset level
it stops scanning and receives the signal. The setting on system code 9955 is
available only when “0” (SQ working condition) is selected here.
Setting range: 0 (Squelch working condition is effective as set on code 9995),
1-10 (S-meter level); Factory setting 3
9952 Scan/sweep-stop time
When a signal is detected, the receiver stops scanning/sweeping and dwells on
this channel frequency. When “0” (RX) is selected, the receiver keeps receiving
until the traffic goes out of this channel frequency. Define the dwell time
between 1 and 99 s.
Setting range: 0 (RX), 1-99 s; Factory setting 2

The loudspeaker reproduces a sound when the signal is lower than the preset
frequency.
Squelch OPEN:
Audio signal is detected and a sound is reproduced through the loudspeaker.
Squelch CLOSED:
No input signal but only noise is coming into the receiver. The receiver is
muted.
1: Level
The squelch is activated depending on “signal strength”. The factory setting is
“5”. You can change the level between 0 - 10 on system code 9956.
2: And
The squelch opens when both “voice” and “signal strength” meet the setting.
3: Or
The squelch opens by either “voice” or “signal strength”, whichever meets the
setting.
9956 Squelch level. Setting range: 0-10; Factory setting 5.
9957 Squelch delay - a delay until the squelch mutes (closes) the receiver after the
signal has gone.

Squelch closes 1000 ms after the signal has gone.
Setting range: 500-4000 ms; Factory setting 1000 ms.
