Voice squelch control function
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 re-
sumes.
➥
While a phone mode (SSB, AM or FM) is selected,
push [VSC]
(MF7) to switch the VSC (Voice Squelch
Control) function ON and 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.

Scan set mode
When the squelch is open, scan continues until it is

resume condition. Scan speed and the scan resume
condition can be set using the scan set mode.
