written
into the CPU
and maintained
until a new offset
frequency is reset.
NOTE:
OFFSET WRITE can be reset on FM mode only in
10KHz
steps,
however
if the
TUNING
RATE
SWITCH
has been pushed ON, OFFSET WRITE
can be reset on any mode with 1KHz steps.
What to do if you want to operate repeaters that have a
frequency
separation other than 7.6MHz
(U.S.A. version:
5.0MHz) (for example; 4.6MHz).
FOR
EXAMPLE:
Select
VFO
A and
FM
mode,
then push the OFFSET
WRITE
button, and the FREQUENCY
DISPLAY
shows
. "07.600".
While
pushing the
OFFSET
WRITE
button,
turn the tuning control counterclockwise to show "04.600"
on the display, then release the OFFSET WRITE button.
Displayed while push-
ing the OFFSET
WRITE button.
Displayed by turning
the TUNING CON-
TROL while the OFF-
SET WRITE button is
pushed.
Push the —DUPLEX
button
to show
'—DUP"
on the
display and tune to 437.725MHz.
''437.725.0"
will be
shown
on
the
display
during
receive
and
''433.125.0"
during transmit.
You
are now
receiving on 437.725MHz
and transmitting
on
433.125MHz,
so
you
can
access
a 433.125/437.725
repeater.
Receiving
Transmitting
If you change the receiving frequency from 437.725MHz to
437.675MHz,
the transmitting frequency will change from
433.125MHz
to 433.075MHz,
so now
you can access
a
433.075/437.675 repeater.

DIAL
FUNCTION
SELECT
SWITCH
(IN VFO
MODE)
In the VFO mode, by pushing the DFS (DIAL FUNCTION
SELECT) switch in, the operating frequency is locked on
the displayed frequency and by turning the TUNING CON-
TROL,
the MEMORY
CHANNEL
NUMBER
displayed on
the frequency display can be changed.
This is very con-
venient to memorize
the operating frequency and modes
into
a memory
channel,
or to change the operating fre-
quency and modes to ones in a memory channel.
FOR
EXAMPLE:
Now
you
are
operating on 432.471MHz
and
USB,
and
memory channel number "07" is displayed.
If you want to
memorize
these into memory
channel
27, push the DFS
switch
in and
you
can
change
the
displayed
memory
channel number by turning the tuning control.
Turn
the
tuning
control
to obtain
the desired
memory
channel
number
(at this
time
"27"),
then
push
the
MEMORY
WRITE
button,
and the operating
frequency
"432.471MHz"
and
mode
"USB'
are memorized
into
memory
channel
27.
To change the operating frequency
again, push and release the DFS switch.
On the display
Pushing the DFS
switch and turning
the TUNING CONTROL.
By pushing the MEMORY
WRITE
button, the frequency
and mode are memorized
into the MEMORY
CHANNEL
27.
FOR
EXAMPLE:
Now you are operating on 432.471MHz
USB and memory
channel 7 memorizes "438.725MHz"', "FM" and "—DUP".
If you wish to operate with the frequency and modes which
are memorized
in the memory
channel 7, push the DFS
switch in and turn the tuning control to display memory
channel
number
"07".
Then
push
the
FREQUENCY
TRANSFER
button, and "438.725.0", "FM'' and "—DUP"
appeare on the frequency
display.
Now you can operate
on this frequency and modes, and by pushing and releasing
the DFS switch, the displayed frequency can be changed
by turning the tuning control.
Contents of the:
memory
channel 7.
Pushing the DFS switch
and turning the TUNING
CONTROL.
