4. Scan Operation

4.1 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 in use, the selected
weather channel is checked while scanning. (p. 38)
Set the tag channels (scanned channel) before scanning.
Clear the tag channels which inconveniently stop scanning,
such as those for digital communication use.
Note: Choose Priority or Normal scan in Set mode. (p. 38)
NORMAL SCAN
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.

PRIORITY SCAN
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.
