VX-8R O PERATING M ANUAL14OPERATIONSQUELCH ADJUSTMENTThe VX-8R’s Squelch system allows you to mute the background noise when no signal isbeing received. Not only does the Squelch system make “standby” operation more pleas-ant, it also significantly reduces battery current consumption.The Squelch system may be adjusted independently for the FM and Wide-FM (FM Broad-cast) modes.1. Press the key, then press the key on the leftside of the radio. This provides a “Short-cut” to SetMode Item 92: SQL LEVEL92: SQL LEVEL92: SQL LEVEL92: SQL LEVEL92: SQL LEVEL.2. Now, rotate the DIAL knob to the point where the back-ground noise is just silenced (typically at a setting ofabout “3” or “4” on the scale); this is the point of maxi-mum sensitivity to weak signals.3. When you are satisfied with the Squelch threshold setting,press the PTT key briefly to save the new setting and exit tonormal operation.4. You may also adjust the Squelch setting by using the “Set”(Menu) mode. See page 157 for details.1) The Squelch level may be set on the “Main” and “Sub” bands separately.2) If you’re operating in an area of high RF pollution, you may need toconsider “Tone Squelch” operation using the built-in CTCSS Decoder. Thisfeature will keep your radio quiet until a call is received from a station sending a carrierwhich contains a matching (sub audible) CTCSS tone. Or if your friends have radiosequipped with DCS (Digital Coded Squelch) like your VX-8R, try using that mode forsilent monitoring of busy channels.24- HOUR C LOCKThe VX-8R has a 24-hour clock with a calendar which covers all dates from Janu-ary 1, 2000 through December 31, 2099.
