SCAN OPERATION

I 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 06
CH 05
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.

CH 02
CH 16 CH 03
CH 04
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. 45)
NORMAL SCAN
CH 01
CH 06
CH 05
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.
