Scan types
Scanning is an efcient 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)
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)
PRIORITY SCAN
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.

NORMAL SCAN
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.
