Scan types
• The scan function can be used on the main read-
out only.
• You can operate 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.

Preparation
• Channels
For programmed scan:
Program scan edge frequencies into scan edge mem-
ory channels P1 and P2.
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 mem-
ory channels. To designate the channel as a select
memory channel, choose a memory channel, then
push [F-3•SELECT] 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 de-
tecting a signal in set mode. Scan resume ON/OFF
must be set before operating a scan. See p. 9-3 for
ON/OFF setting and scan resume condition details.
• Scan speed
Scan speed can be selected from 2 levels, high or low,
in scan set mode. See p. 9-3 for details.
• Squelch condition

Scan stops when detecting a signal.
If you set scan resume ON in set mode, the
scan pauses for 10 sec. when detecting a
signal, then resumes. When a signal disap-
pears while scan is paused, scan resumes
2 sec. later.
The scan continues
until it is stopped
manually, and does
not pause even if it
detects signals. Scan pauses on
each channel when
the scan resume is
ON; not applicable
when OFF.
