LARIFIER
The Clarifier (RIT) allows you to set an offset of up to ±9.99
kHz of the receive frequency relative to your transmit fre-
quency. To achieve a wider offset than this, you may use the
"Split" operating mode, described later.

1. Press the CLAR/IF SHIFT button momentarily to acti-
vate the Clarifier function.
2. Turn the CLAR knob, which allows the receiver fre-
quency to be varied over a range of ±9.99 kHz.
3. When the receiving frequency is
higher than transmit frequency, the
" (within 1 kHz)" or " (exceed 1
kHz)" icon will appear at the right
of the frequency display. Similarly,
when the receiving frequency is
lower than transmit frequency, the
" (within 1 kHz)" or " (exceed 1
kHz)" icon will appear at the right
of the frequency display. When the
receiving frequency is equal to trans-
mit frequency (Clarifier offset is
zero) while the Clarifier is activated,
the "–" icon will appear at the right
of the frequency display.
4. To turn the Clarifier off, again press
the CLAR/IF SHIFT button mo-
mentarily. When you turn the Clari-
fier back on, the offset previously
stored will still be applied.
5. To reset the Clarifier offset to zero, turn the Clarifier off,
then turn the DIAL by any amount. The Clarifier will
reset to zero after the first "step" of the DIAL.
1) If you leave the Clarifier on, moving the DIAL
will not cause the offset to be cancelled.
2) You may change the knob that controls the
Clarifier offset from the DIAL to the MEM/VFO
CH knob via Menu Mode No-021 [ CLAR DIAL SEL ] .
