Scan types
■
Preparation
• Channels
For programmed scan:
Program scan edge frequencies into scan edge
memory channels P1 and P2. (p. 109)
For
∂
F scan:
Set the ∂ F span ( ∂ 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
Select memory channel, choose a memory channel,
then push
[SELECT] (F-3) in the scan screen
(memory 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 the scan set mode. Scan resume
ON/OFF must be set before performing a scan. See
page 114 for ON/OFF setting and scan resume
condition details.
• Scan speed
Scan speed can be selected from 2 levels, high or
low, in the scan set mode. See page 114 for details.
• Squelch condition
❍
Scan starts with the squelch open
For programmed scan:
When the 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, or the scan is cancelled
when the scan resume is OFF).
When the tuning step is more than 5 kHz:
The scan pauses on each step when the scan
resume is ON. This is not applicable when the scan
resume is OFF.
For memory scan:
Scan pauses on each channel when the scan resume
is ON. This is 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 the 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.

SCANS
PROGRAMMED SCAN
Repeatedly scans between two scan edge frequencies
(scan edge memory channels P1 and P2).
This scan operates in the 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 the memory mode. This scan operates in the memory mode.
This scan operates in both the VFO and memory modes.

• You can perform a scan while operating on a
frequency using the dualwatch or split functions.
