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 receiver
checks received signals for voice components.
If a receiver signal includes voice components, and
the tone of the voice components changes within 1
second, scan pauses (or stops). If the received sig-
nal includes no voice components or the tone of the
voice components does not change within 1 second,
scan resumes.
➥ While a phone mode (SSB, AM or FM) is selected,
push [VSC] to switch the VSC (Voice Squelch Con-
trol) function ON or OFF.
• "VSC" appears when the function is activated.
• The VSC function activates for any scan.
• The VSC function resumes the scan on unmodu-
lated signals, regardless of whether the scan re-
sume condition is set to ON or OFF.
When the squelch is open, scan continues until it is
stopped manually— it does not pause on detected sig-
nals. 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.
