ADVANCED PROGRAMMING MODE (ULXP4 MODELS ONLY)

Scanning Frequency Groups

1. Hold down the receiver SET button and press the MODE button once. The words GROUP and SCAN will flash on the
display. Refer to Figure 37.
2. To begin scanning, rotate the control knob one quarter turn clockwise, as shown in Figure 38. The receiver will automati-
cally begin scanning each Channel in all Groups. This may take up to two minutes, and the word "bUSY" will appear
on the display.
3. When all Groups have been scanned, the Group with the most open Channels will appear on the display, as shown in
Figure 39.
4. To tune the receiver to the new Group, press the SET button. An open Channel in this Group will automatically be
scanned and saved in the background. The display will then return to the default mode, as shown in Figure 40. If you
choose not to accept the receiver's recommended Group, rotate the control knob to the right to scroll through the list
of scanned groups.

Adjusting the Receiver Squelch Setting

The receiver squelch control is factory preset for optimum performance. Normally, no further adjustment is required. Howev-
er, 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.
