9 SCANS■Scan typesPROGRAMMED SCAN

Repeatedly scans between two scan edge frequencies (scan edge memory channels P1 and P2).

Scan edge	Scan edge
P1 or P2	P2 or P1

Scan

Jump

This scan operates in VFO mode.

• The scan function can be used on the main read-

out only.

• You can operate a scan while operating on a frequency using the split functions.

∂F SCAN

Repeatedly scans within ∂F span area.

Start frequency

–∂F frequency +∂F frequency

Scan Scan

Jump

This scan operates in both VFO and memory modes.

MEMORY SCAN

Repeatedly scans all programmed memory channels.

Blank channel

	Mch 2	Mch 3	Mch 4
	★2	★1
Mch 1	*“★1,” “★2” and “★3” show that the channel Mch 5
★1	is specified as the select memory.		★1
	Mch 99	Mch 7	Mch 6
	★1	★1	★3

This scan operates in memory mode.

SELECT MEMORY SCAN

Repeatedly scans all or one of 3 select memory channels.

Blank channel

	Mch 2	Mch 3	Mch 4
	★2	★1
Mch 1 *“★1,” “★2” and “★3” show that the channel				Mch 5
★1	is specified as the select memory.			★1
	Mch 99	Mch 7	Mch 6
	★1	★1	★3

This scan operates in memory mode.

■Preparation• Channels

For programmed scan:

Program scan edge frequencies into scan edge memory 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 memory 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 detecting 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
