5 SCAN OPERATION

■Scan types

Scanning is an efficient way to locate signals quickly over a wide frequency range. The transceiver has Priority scan and Normal scan.

When the weather alert function is turned ON, the previously selected (used) weather channel is also checked while scan- ning. (p. 31)

PRIORITY SCAN

 

CH 01

CH 02

CH 06

CH 16

CH 03

 

CH 05

CH 04

Priority scan searches through all tag channels in sequence while monitoring Channel 16. When a signal is detected on Channel 16, scan pauses until the signal disappears; when a signal is detected on a channel other than Channel 16, scan becomes Dualwatch until the signal disappears.

Set the tag channels (scanned channel) before scanning. Clear the tag channels which inconveniently stop scanning, such as those for digital communication use.

Choose Priority or Normal scan in Set mode. (p. 31)

NORMAL SCAN

CH 01

CH 02

CH 06

CH 03

CH 05

CH 04

Normal scan, like Priority scan, searches through all tag channels in sequence. However, unlike priority scan, Chan- nel 16 is not checked unless Channel 16 is set as a tag channel.
