4 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 (last used) weather channel is also checked while scanning. (p. 56)

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. (Refer to right page for details.)

Choose Priority or Normal scan in Set mode. (p. 55)

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, Channel 16 is not checked unless Channel 16 is set as a TAG channel.
