Scan types
• The scan function can be used on the main read
-
out only.
• You can perform a scan while operating on a fre
-
quency using the split functions.
PROGRAMMED SCAN
Repeatedly scans between two scan edge frequencies
(scan edge memory channels P1 and P2).
This scan operates in VFO mode.
SELECT MEMORY SCAN
Repeatedly scans all or one of 3 select memory channels.
∂
F SCAN
Repeatedly scans within
∂
F span area.
This scan operates in memory mode.
This scan operates in memory mode.
This scan operates in both VFO and memory modes.

SCANS
■
Preparation
• Channels
For programmed scan:
Program scan edge frequencies into scan edge mem-
ory channels P1 and P2.
For
Δ
F scan:
Set the
Δ
F span (
Δ
F scan range) in the scan screen.
For memory scan:
Program 2 or more memory channels except scan
edge memory channels.
For select memory scan:
Designate 2 or more memory channels as select
memory channels. To designate the channel as a se-
lect memory channel, choose a memory channel,
then push [SELECT]
F-3
in the scan screen (mem-
ory mode) or in the memory list screen.
• Scan resume ON/OFF
You can select the scan to resume or cancel when
detecting a signal in set mode. Scan resume ON/OFF
must be set before performing a scan. See page 9-3
for ON/OFF setting and scan resume condition de-
tails.
• Scan speed
Scan speed can be selected from 2 levels, high or
low, in scan set mode. See page 9-3 for details.
• Squelch condition
❍
Scan starts with squelch open
For programmed scan:
When tuning step is 1 kHz or less:
The scan continues until it is stopped manually— it
does not pause* even if signals are detected.
* The scan is paused when the squelch is closed and
then opened (scan resumes after 10 seconds has
passed when the scan resume is ON; scan is cancelled
when the scan resume is OFF).
When tuning step is more than 5 kHz:
The scan pauses on each step when the scan
resume is ON; not applicable when the scan
resume is OFF.
For memory scan:
Scan pauses on each channel when the scan resume
is ON; not applicable when the scan resume is OFF.
❍
Scan starts with squelch closed
Scan stops when a signal is detected.
• If the scan resume is set to ON in scan set mode, the
scan pauses for 10 seconds when detecting a signal, then
resumes. When a signal disappears while scan is paused,
scan resumes 2 seconds later.
