3-5 Adjusting the Squelch level

The SQUELCH control enables you to set the levels of your desired signal. It determines how strong your signal can be before you can hear it, before it “breaks squelch.” It aims to keep any static, unwanted, weak or distant signals from interrupting your conversations.

There are 16 signals to choose from when adjusting the squelch level. To increase the levels, raise the “Squelch Gate” higher so that only stronger signals can get through. Level “0” for instance, means that there is no “Squelch Gate” and everything will get through.

To adjust the squelch level, press SQ / accordingly.

3-6 Volume control

Press VOL / to adjust the volume level. A volume sub-menu will appear when pressed. It times-out after 5 seconds.
