SCANS

Scan types

VFO SCAN
Used to detect a signal by automatically changing the
frequency of the VFO mode.
Programmed scan
Repeatedly scans the Program scan edge ranges.
The Edge frequencies are programmable. (p. 8-5)
Fine Programmed scan
If the squelch opens while scanning, the tuning
step changes to 10 Hz. This reduces the scan
speed, but the transceiver keeps scanning.
MEMORY SCAN
Used to detect a signal by automatically scanning the
memories in the Memory mode.
Memory scan
Repeatedly scans all entered Memory channels or
Memory channels in the selected group.
Select Memory scan
Repeatedly scans Select Memory channels.
Mode Select scan
Repeatedly scans Memory channels with the same
operating mode.
∂F SCAN
Repeatedly scans within the ∂F span area.
The scan starts from the center frequency.
Fine ∂F scan
If the squelch opens while ∂F scanning, the tuning
step changes to 10 Hz. This reduces the scan speed,
but the transceiver keeps scanning.

Preparation

DSquelch status

The scan works with the selected band's squelch
status. Be sure to adjust the squelch level
(p. 8-4)
according to your operating environment.
LNormally, set the squelch level to the point where
the noise just disappears and the TX/RX indicator
goes OFF.
When the scan starts with the squelch open:
• 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.
• When the tuning step is 5 kHz or more, the scan
(p. 8-6)
pauses on each step when the Scan Resume
function is ON. It does not pause when the function
is OFF.
(p. 8-7)
When the scan starts with the squelch closed:
(p. 8-8)
The scan stops when a signal is detected, regardless
of the tuning step.
LWhen the Scan Resume function is ON, the scan
(p. 8-9)
pauses for 10 seconds after detecting a signal, then
resumes 2 seconds after the signal disappears.
