VX-3R O PERATING M ANUAL22S-METER SQUELCHA special S-meter Squelch feature is provided on this radio. This feature allows you to setthe squelch so only signals exceeding a certain S-meter level will open the squelch.To set up the S-meter squelch circuit for operation, use the following procedure:1. Press and hold in the [TXPO] key for one second to enter the Set mode.2. Rotate the DIAL knob to select Set Mode Item 80: SQSMTRSQSMTRSQSMTRSQSMTRSQSMTR.Note: Do not forget to pull the DIAL knob to rotate the DIALknob.3. Press the [TXPO] key momentarily to enable adjustment of thisItem.4. Rotate the DIAL knob to select the desired signal strength levelfor the squelch threshold (LVL 1LVL 1LVL 1LVL 1LVL 1 - LVL8LVL8LVL8LVL8LVL8 or OFFOFFOFFOFFOFF).5. Press the PTT switch to save the new setting and return to normal operation.1) When the S-meter squelch is activated, the S-metersegment corresponding to the squelch threshold whichwas set by step 4 above will blink.2) The receiver’s squelch will open based on the higher of the lev-els set by the two squelch systems (Noise Squelch and S-meter Squelch).For example:a) If the Noise Squelch (SQL control) is set so that signals at a level of “S-3” will openthe squelch, but the S-meter Squelch (Set Mode Item 80) is set to “LVL 5,” the squelchwill only open on signals which are “S5” or stronger on the S-meter.b) If the S-meter Squelch is set to “S3,” but the Noise Squelch is set to a high level whichwill only pass signals which are Full Scale on the S-meter, the squelch will only open onsignals which are Full Scale on the S-meter. In this case, the Noise Squelch overridesthe action of the S-meter Squelch.ADVANCED OPERATION
