85FT-857 Operating Manual“PRIORITY CHANNEL” SCANNINGThe FT-857’s scanning features include a two-channel scanning capability which allowsyou to operate on a VFO or Memory channel, while periodically checking Memory Channel“M-001” for activity. If a station is received on Memory Channel “M-001” which is strongenough to open the Squelch, the scanner will pause on that station in accordance with theScan-Resume mode set via Menu Mode No-077 [SCAN MODE]. See page 110.Here is the procedure for activating Priority Channel Dual Watch operation:1. Rotate the SQL control until the background noise is just silenced, then store the fre-quency to be the “Priority” channel into Memory Channel “M-001.”2. Set the FT-857 for operation on another memory channel, or on a VFO frequency.3. Press the [FUNC] key momentarily, then rotate the SELECT knob, as needed, untilMulti Function Row “g” [SCN, PRI, DW] appears on the display.4. Press the [B](PRI) key momentarily to start the “Priority” monitoring feature (the “ ”icon will appear at the upper of the frequency display). During Priority monitoring, thedisplayed frequency will shift to the Priority memory briefly every five seconds, whilethe receiver checks for the presence of a signal.5. When no signal appears on the Priority memory (i.e. the squelch remains closed), youcan tune, transmit and receive on the VFO, or select and operate on other memories.6. If a station you wish to talk with appears on the Priority channel, press the PTT switchmomentarily while receiving their signal (no transmission will occur) to halt Priorityscanning. Otherwise, when a signal appears on the Priority channel, Priority monitoringwill just pause on the channel. Priority monitoring will resume in accordance with theSCAN MODE Menu setting, as mentioned previously.7. To cancel Priority monitoring, again press the [B](PRI) key.SCANNING OPERATION
