Turn power off, then on again to exit initial set mode. 24 SCAN OPERATION 8 I Programmed scan Programmed scan repeatedly scans between two user-programmed frequencies (memory channels "PA" and "Pb"). This scan is useful for checking for signals within a specific frequency range such as repeater output frequencies, etc. I Memory (skip) scan Memory scan repeatedly scans all programmed memory channels, except those set as skip channels. Push [A V] to select memory mode, if necessary. · "X" appears. Push [A V] to select VFO mode, if necessary. Push [SC] to start the scan. · To change the scan direction, push [Y] or [Z]. Push [SC] to start the scan. · To change the scan direction, push [Y] or [Z]. Push [SC] again to stop the scan. NOTE: Scan edges, PA/Pb, must be programmed in advance (program them in the same manner as regular memory channels--p. 19). If the same frequencies are programmed into the scan edges, programmed scan will not proceed. Push [SC] again to stop the scan. D Setting skip channels In order to speed up the scan interval, you can set memory channels you don't wish to scan as skip channels. Push [A V] to select memory mode, if necessary. · "X" appears. Push [Y]/[Z] to select a memory channel to set as a skip channel. Push [SC] for 1 sec. to toggle the skip setting on/off.

Like repeater tones, these are set in set mode. I Tone squelch D Operation The tone squelch opens only when receiving a signal containing a matching subaudible tone. You can silently wait for calls from group members using the same tone. Set the operating frequency. Set the desired subaudible tone in set mode. · See right for programming. Push [C T] one or more times until "TSQL" appears. When the received signal includes a matching tone, squelch opens and the signal can be heard. · When the received signal's tone does not match, tone squelch does not open, however, the S-indicator shows signal strength. · To open the squelch manually, push and hold [ ]. Select VFO or a memory channel. Push [A V] for 1 sec. to enter set mode. Push [t] one or more times until T SQL Operate the transceiver in the normal way. To cancel the tone squelch, push [C T]. NOTE: The transceiver has 50 tone frequencies and consequently their spacing is narrow compared to units having 38 tones. Therefore, some tone frequencies may receive interference from adjacent tone frequencies.
