Adjusting the Receiver Squelch Setting

The receiver squelch control is factory preset for optimum performance. Normally, no further adjustment is required. How- ever, it is possible to adjust the squelch control to improve either signal quality or increase system range.

NOTE: Increasing the Squelch level causes the receiver to demand a higher quality signal (less noise before muting), but it reduces operating range. Decreasing the Squelch level allows a lower quality signal through (more noise before muting), but extends the operating range.

1.Hold down the receiver SET button and press the MODE button twice. “SQLCH” will flash on the display, as shown in

Figure 41.
