5 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. 48) PRIORITY SCAN CH 01 CH 02 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 the right page for details.) Choose Priority or Normal scan in the Set mode. (p. 47) NORMAL SCAN CH 01 CH 02 CH 06 CH 16 CH 03 CH 06 CH 03 CH 05 CH 04 Priority scan sequentially searches through all TAG channels while monitoring Channel 16. When a signal is detected on Channel 16, the scan pauses until the signal disappears; when a signal is detected on a channel other than Channel 16, the scan switches to Dualwatch until the signal disappears. 14 CH 05 CH 04 Normal scan, like priority scan, sequentially searches through all TAG channels. However, unlike priority scan, Channel 16 is not checked unless it is set as a TAG channel.
