” S

The FT-857’s scanning features include a two-channel scanning capability which allows
you 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 strong
enough to open the Squelch, the scanner will pause on that station in accordance with the
Scan-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, until

Multi 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, the
displayed frequency will shift to the Priority memory briefly every five seconds, while
the receiver checks for the presence of a signal.

5. When no signal appears on the Priority memory (i.e. the squelch remains closed), you

can 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 switch

momentarily while receiving their signal (no transmission will occur) to halt Priority
scanning. Otherwise, when a signal appears on the Priority channel, Priority monitoring
will just pause on the channel. Priority monitoring will resume in accordance with the
SCAN MODE Menu setting, as mentioned previously.

7. To cancel Priority monitoring, again press the [B](PRI) key.
