7R’s Squelch system allows you to mute the background noise when no
signal is being received. Not only does the Squelch system make “standby” operation
more pleasant, it also significantly reduces battery current consumption.
The Squelch system may be adjusted independently for the FM and Wide-FM (FM
Broadcast) modes.
1.
Press the [MON/F] key, then press the MONI switch on the left side of the radio.
This provides a “Short-cut” to Menu Item (Basic Setup #1: SQL NFM) or Menu Item
(Basic Setup #2: SQL WFM).
2.
Now, press the [MAIN] or [SUB] key to set the background noise is just silenced
(typically at a setting of about “3” or “4” on the scale); this is point of maximum
sensitivity to weak signals.
3.
When you are satisfied with the Squelch threshold setting, press the PTT key
momentarily to save the new setting and exit to normal operation.
4.
You may also adjust the Squelch setting by using the “Set” (Menu) mode. See
page ?? for details.

: If you’re operating in an area of high RF pollution, you may need to consider
“Tone Squelch” operation using the built-in CTCSS Decoder. This feature will keep your
radio quiet until a call is received from a station sending a carrier which contains a
matching (subaudible) CTCSS tone. Or if your friends have radios equipped with DCS
(Digital Coded Squelch) like your VX-

and operating modes. You can change the channel steps and operating modes later, if
you like (see page ??).
