SCANS
7-2
Scan types
VFO SCAN
Used to detect signals by automatically changing the
frequency of the VFO mode�
Programmed scan
Repeatedly scans the Program Scan Edge ranges�
The Edge frequencies are programmable� (p� 7-6)
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 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
D
Squelch status
The scan works with the selected band’s squelch
status� Be sure to adjust the squelch level according
to your operating environment�
L
Normally, set the squelch level to the point where the
noise just 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�
When the scan starts with the squelch closed:
The scan stops when a signal is detected, regardless
of the tuning step�
L
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�
