SCANS
Scan types
VFO SCAN
Used to detect signals by automatically changing the
frequency of the VFO mode.
Programmed scan
Repeatedly scans between two Scan Edge
frequencies.
The Edge frequencies are programmable, and are
preset in P1 and P2 as the default. (p. 7-2)
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 signals by automatically scanning the
memories in the Memory mode.
Memory scan
Repeatedly scans all entered Memory channels.
Select Memory scan
Repeatedly scans Select Memory channels.
∂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
D Squelch status
The scan works with the Main band's squelch status.
Be sure to adjust the squelch level according to your
(p. 8-4)
operating environment.
L Normally, set
disappears and the 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
pauses on each step when the Scan Resume
function is ON. It does not pause when the function
is OFF.
(p. 8-5)
When the scan starts with the squelch closed:
(p. 8-5) The scan stops when a signal is detected, regardless
of the tuning step.
L When the Scan Resume function is ON, the scan pauses
(p. 8-7)
for 10 seconds after detecting a signal, then resumes 2
seconds after the signal disappears.
