5 SCAN OPERATIONS

Scan types

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

PRIORITY SCAN

CH 01

 

CH 02

CH 06

CH 16

CH 03

CH 05

 

CH 04

Priority scan searches through all tag channels in se- quence while monitoring Channel 16. When a signal is de- tected on Channel 16, scan pauses until the signal disap- pears; when a signal is detected on a channel other than Channel 16, scan becomes dualwatch until the signal dis- appears.

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 scan or normal scan in set mode in ad- vance. (p. 15)

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.
