the little oval area just below the PTT switch
on the side of the radio, the Squelch is over-
ridden, and you can then use the background noise
tu
set the volume level, even if there aren't any incoming
signals.
Squelch Adjustment
The VX-IR initially is set to the "Auto-Squelch"
mode, which automatically optimizes the Squelch
setting to silence background noise under typical
operating conditions. We recommend that you in-
itially use the Auto Squelch setting, and only change
it if your operating environment causes the squelch to
open unnecessarily.
To change the Squelch Setting:
D
Press the
~
key momentarily, then immediately
press·~
(above the VOL label, notice the SQL label
in orange type, signifying that this is the function
activated after the
19
key is pushed).
D
The default condition of the Squelch is Auto-
Squelch, which is labeled
S'!JL RU
i
on the display.
Tum the Dial clockwise to select from the other
options. The first click of the Dia] is
~/]L
DPEfJ,
which opens the Squelch to pass background noise
(as if you had pushed the Monitor switch). Further
rotation of the Dial allows manual setting of the
squelch threshold, on a scale of 1 to 10. Advance
the Dial to the point where the background noise is
just silenced. Turning the Dial to a higher number
reduces the sensitivity of the Squelch system to
weak signals.
0
About two seconds after you stop turning the Dial,
the transceiver automatically cancels the Squelch
Setting mode, and the display reverts to the operat-
ing frequency.

R. F. Says: If you're operating in an area of
~~
high RF activity; you may want to make use of
"Tone Squelch" operation with the built-in
CTCSS Decoder. This keeps your radio quiet until a
call is received from a station sending u matching
( subaudible) CTCSS tone. Or if your friend(
s)
have
radios equipped with DCS (Digital Code Squelch)
like your VX-1 R has, try using that mode fur more
silent monitoring of busy channels.
Selecting the Operating Band
The VX-!R covers an incredibly wide frequency
range, over which several different operating modes
are used. Therefore, the VX-IR's frequency coverage
has been divided into different operating bands, each
having its own pre-set channel steps and operating
modes. You can change the channel steps and operat-
ing mode later, if you like (page 17).
