• Channels
For programmed scan/auto memory write scan:
Program scan edge frequencies into scan edge
memory channels P1 and P2.
Program scan edge frequencies into scan edge
memory channels P1 and P2.
For memory scan:
Program 2 or more memory channels except scan
edge memory channels.
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
select memory channel, select a memory channel,
then push [SEL] in the scan screen (memory mode)
or in the memory channel screen.

For priority watch:
Program 1 or more memory channels.
Program 1 or more memory channels.
• 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 operating a scan. See p. 31 for ON/
OFF setting and scan resume condition details.

• Scan speed
Scan speed can be selected from 2 levels, high or
low, in set mode. See p. 31 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 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 sec. has passed
when the scan resume is ON; scan is cancelled when
the scan resume is OFF).
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.
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 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 sec. when detecting a signal, then resumes.
When a signal disappears while scan is paused, scan
resumes 2 sec. later.
When a signal disappears while scan is paused, scan
resumes 2 sec. later.
PROGRAMMED SCAN/AUTO MEMORY WRITE SCAN
Repeatedly scans between two scan edge frequencies
(scan edge memory channels P1 and P2). Auto memory
write scan automatically memorizes paused frequencies
into memory channels 80 to 99.
