Selcall Scan
When a Selcall signal is detected, and the channel has Selcall enabled, no mat-

the Selcall. The Transceiver will only stop scanning when a Selcall is detected.
Signal Strength Scan (SSL Scan)
If the signal strength mute (squelch) is active and a signal with a level greater
than the pre-set threshold is received, the scan will halt. Scan will remain
halted while the signal level stays above the preset threshold. Once the signal
decreases below the pre-set threshold level, for a period greater than the scan
dwell period, scanning will resume.
See page 77 for information on the SSL pre-set threshold and page 73 for
information on the scan dwell period.
Voice (Syllabic) Scan
If the audio mute (squelch) is active and is opened, scanning will halt. Scanning
will remain halted while the audio mute is open. Once the mute closes for a
period greater than the scan dwell period, scanning will resume.
