UNIDEN UH825 Handheld UHF-CB Transceiver
Operation
Squelch
The squelch is used to eliminate the annoying background noise when
there is no signal present on a channel. The squelch circuit does this by
controlling when the radio’s speaker turns on, based on the strength of
received signals.
NOTE
Make sure to first select a channel not in use before setting
the squelch in your UH825 UHF-CB radio.
The Auto Squelch feature has 0-5 preset squelch levels:
0 - max sensitivity (min squelch):
Speaker is ON.
2 - med sensitivity (med squelch):
Default setting.
5 - min sensitivity (max/tight squelch):
Less interference.
It requires no adjustment.
To set the Squelch level:
1. Press [MENU/MON] 2 times to enter
the squelch setting list.
2. Press
[ ]
or
[ ]
to select the
desired squelch level 0-5.
3. Press & hold [SCAN/MEM] to save the setting.
NOTE
If an incoming signal is very weak there is a possibility that
you will have a choppy or broken reception, due to the
sensitivity of the squelch. In this case, adjust the squelch
level accordingly.

SQUELCH
The squelch is used to eliminate any annoying background noise when there
are no signals present.
Think of squelch as a gate. Turn [SQ] fully
clockwise. This raises the "Squelch Gate" so high
that only the very strong signals can get through.
Turn [SQ] fully counter clockwise until you hear a
hiss. This opens the "Squelch Gate" so that
everything gets through noise, weak signal, and
strong signals.
To set the "Squelch Gate" to the desired level, turn
[SQ] counter-clockwise until you hear noise. Then
turn the [SQ] clockwise just until the noise
stopped. Now only the desired signal can get
through.
If an incoming signal is very weak there is a
possibility that you will have a choppy or broken
reception, due to the sensitivity of the squelch.
In this case, simply rotate the
[SQ] clockwise
until the weak signal is heard clearly.
