Example: To enter 7.160000 MHz, press
VFO A ENTER, "7", ".", "1", "6", VFO A
ENTER. When VFO A ENTER is pressed
the second time during a direct frequency
entry, the remaining digits will be filled with
zeros. Note: If VFO A is assigned to the
main receiver, and you try to enter a non-
ham frequency, FREQUENCY NOT
SUPPORTED will appear on the screen and
you will be returned to the last frequency
used before attempting the invalid direct
entry.
(59) VFO B ENTER
Refer to instructions for (58) VFO A ENTER.
VFO B ENTER works exactly the same,
except the entered frequency will be for
VFO B.
(60) A>B, B>A, A/B
Frequencies can quickly be copied or
"flipped" between VFOs by pressing the
A>B, B>A, or A/B buttons. A>B copies
frequency information from VFO A to VFO
B. B>A copies frequency information from
VFO B to VFO A. A/B "flips" the two VFO's
frequency information; what was shown for
A copies to B, what was shown for B copies
to A.
Note that if trying to copy or flip a non-ham
frequency to the main receiver that the radio
will show an error message on the screen
and revert to the last used frequencies
before the invalid action was attempted.
If the main receiver is assigned to VFO A
and the sub receiver is assigned to VFO B
(or vice versa), mode and frequency
information will also be copied between
VFO's when pressing A/B, A>B, B>A. If the
receivers are both assigned to the same
VFO, or either the main receiver or sub
receiver are not assigned to a VFO, then
only frequency information will be copied
between the VFO's. See (8 – 13) VFO
ASSIGNMENTS elsewhere in the manual
for a description of how receivers are
assigned to VFO's.
Additionally, the A/B button is used to
change the default VFO for band changing
with the keypad. Next to the two frequency
displays at the extreme left of the screen are

the "A" and "B" annunciators. One of the
two will be highlighted in reverse text to
indicate it is the entry VFO for the band
change keypad. To change, press and hold
the A/B button for two seconds. Please note
that the default is for VFO A, and powering
off the transceiver will revert it to the default.
