This function is useful when you don't want unmodu-
lated signals pausing or cancelling a scan. When the
voice squelch control function is activated, the trans-
ceiver checks received signals for voice components.
If a received signal includes voice components, and
the tone of the voice components changes within
1 sec., scan pauses (or stops). If the received signal
includes no voice components or the tone of the voice
components does not change within 1 sec., scan
resumes.

stopped manually— it does not pause on detected
signals. When squelch is closed, scan stops when de-
tecting a signal, then resumes according to the scan
resume condition. Scan speed and the scan resume
condition can be set using the scan set mode.
