Function
Symbol
When the next preset memory is called at the end of 5 second hold, BEEP is output.
During 5-second hold, the preset memory number display flashes at 1 Hz (duty 50 %). The
“ch” display does not flash.
To stop at that preset memory during 5-second hold, press this key again, or press the
same preset memory key as the preset memory being received. Writing of preset memory
(for example, writing to M5 during M1 hold) is also possible, but the preset memory scan
operation ends when the preset memory was written.
The preset memory write operation during 5 second hold is described below.

Description
When the
key is pressed, the device enters the 5-second memory write mode.
Writing is performed by pressing a
to
key in the memory
writable mode. At the end of writing, auto preset memory scanning stops. In the memory
writable mode, the “ch” display flashes. If no operation is performed within 5 seconds, the next
preset memory channel is called and auto preset scanning continues.
If the
key is pressed again in the memory writable mode, the memory
writable mode is canceled and the next channel is called 5 seconds after the key was pressed.
When a
to
key is pressed for more than 2 seconds, the fre-
quency currently being received is written to the preset memory corresponding to the pressed
key.
Auto preset scanning ends when the frequency was written to the preset memory (2 seconds
after the key was pressed).
