AUTO MODE
You can configure a maximum of 32 frequency
borders (VFO A and B) to change the operating mode
automatically as you change the VFO frequency.
As a default, the following modes are programmed on
each operating band.
0.03 MHz ~ 9.5 MHz: LSB
9.5 MHz ~ 60 MHz: USB
To add the frequency borders to the Auto Mode
selection:
1
With the transceiver power OFF, press and hold
[LSB/USB] + [
]
to turn the transceiver ON.
•
“AUTOMODE” appears on the sub-display.
2
Select an Auto Mode frequency memory channel
number by turning the
MULTI/CH
control.
•
Auto Memory channels 00 to 31 are available.
3
Turn the
Tuning
control to select a desired
frequency border (or enter the frequency with the
keypad {page 29}) to change the operating mode.
4
Press
[LSB/USB]
,
[CW/FSK (REV)]
,
[FM/AM (FM-
N)]
, or
[DATA]
until the desired communication
mode appears.
5
Repeat steps
2

data.
6
Press
[CLR]
to exit the Auto Mode frequency
configuration.
To activate the Auto Mode function:
1
Press
[MENU]
, then press
[Q-M.IN]
