A “SCN” icon and blinking“P” and “MEM” icons will appears at the left of the channel number on thedisplay during scanning. The scan proceeds betweenthe memorized channels and the Priority Channel (Chan-nel 16).As an example of priority scanning, let us say that ma-rine channels “06”, “07”, and “08” are memorized in the transceiver’s scanmemory. Priority scanning will proceed in the following sequence:[CH06] Æ (CH16)Ú Æ [CH07] Æ (CH16)Ú Æ[CH08] Æ (CH16)Ú Æ [CH06] Æ (CH16)Ú Æ [CH07] .....Ú: Priority Channel4. Even when the transceiver stops and listens to the signal of a programmedchannel, the transceiver will “dual watch” between this channel and thepriority channel. This allows the radio to be able to receive calls on chan-nel 16 (priority channel) even when the radio is receiving on another chan-nel.5. To stop the Priority Scanning, press the [SCAN(DW)] key.](https://usermanual.wiki/Yaesu-Musen/30383X20/User-Guide-1052779-Page-24.png)
