TAG CALL USA INT 11 5 SCAN OPERATIONS 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. In addition, weather alert and an automatic scan start function is available for standby convenience. 17, 18) PRIORITY SCAN CH 01 CH 02 Set the tag channels (scanned channel) before scanning. (Clear the tag channels which may inconveniently stop scanning, such as those for digital communication use. ) Choose priority or normal scan in SET mode. 17) NORMAL SCAN CH 01 CH 02 WX* CH 16 CH 03 CH 88 CH 03 CH 05 CH 04 CH 05 CH 04 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. 12 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. SCAN OPERATION 5 I Setting tag channels For more efficient scanning, add desired channels as tag channels or clear preset tag channels if they are unwanted channels. Channels, set as non-tag channels will be skipped during scanning. [. . . ] 16--19) q While pushing [MONI], turn power ON. w Push [MONI] again to select an item.
