ory. If desired, hold down [MW] for 1 second to overwrite

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 scan
pauses while the receiver checks the received signals
for voice components. (The squelch does not open
during this check.)
If a received signal includes voice components, and
the tone of the voice components changes within 1
second, the scan is stopped and the squelch opens.
If the received signal has no voice components, or the
tone of the voice components does not change within
1 second, the scan resumes.
While in a phone mode (SSB, AM or FM), push
[VSC]() to turn the VSC (Voice Squelch Control)
function ON or OFF.
“VSC” is displayed when the function is ON.
The VSC function can be used in any scan.
The VSC function resumes the scan on unmodu-
lated signals, regardless of whether the Scan Re-
sume function is set to ON or OFF.
