■ 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 receiver

checks received signals for voice components.

If a receiver 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 compo-

nents does not change within 1 sec., scan resumes.

➥ While a phone mode (SSB, AM or FM) is selected,

push [VSC] to switch the VSC (Voice Squelch Con-

trol) 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

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.
