Preparation
D Squelch status
Scans work with the squelch status.
Be sure to adjust the squelch level according to your
operating conditions.
L When
AF RF/SQL
operates as only an RF gain
control, you cannot adjust the squelch level.
L Normally, set
AF RF/SQL
to the point where noise
disappears, and the TX/RX indicator goes off.
When the scan starts with the squelch open:
• For a Programmed scan
When the tuning step is 1 kHz or less, the scan
continues until it is manually stopped— it does not
pause* even if signals are detected.
* The scan pauses when the squelch is closed and then
opened. The scan resumes after 10 seconds has passed
when the Scan Resume function is ON. It is cancelled
when the function is OFF.
When the tuning step is 5 kHz or more, the scan
pauses on each step when the Scan Resume function
is ON. It does not pause when the function is OFF.
• For a memory scan
The scan pauses on each channel when the Scan
Resume function is ON. The scan does not pause
when the function is OFF.
When the scan starts with the squelch closed:
The scan stops when a signal is detected.
• When the Scan Resume function is ON, the scan pauses
for 10 seconds after detecting a signal, then resumes 2
seconds after the signal disappears.
