5 SCAN OPERATION

■Scan types

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

In addition, the “Weather alert” and “Auto scan” functions are available for scanning. These functions can be activated si- multaneously, depending on the settings on the SET mode. (pgs. 17, 18)

PRIORITY SCAN

CH 01		CH 02
WX*	CH 16	CH 03
CH 05		CH 04

*Previously selected weather channel when weather alert function is ON

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 those tag channels which are not needed or inconveniently stop scanning, such as digital communications.

Choose priority or normal scan on the SET mode. (p. 17)

NORMAL SCAN

CH 01	CH 02
WX*	CH 03
CH 05	CH 04

*Previously selected weather channel when weather alert function is ON.

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