BUTTONS OF THE
MH-31
A8J
The microphone [ UP
]/[
DWN
] keys utilize the tun-
ing steps of the [ MAIN DIAL
] knob on the SSB/
CW/DATA mode, and utilize the tuning steps of
the [
DSP/SEL
] knob on the AM/FM mode.
When the microphone [ FST
] key is pressed, the
tuning rate increases by a factor of ten, in a man-
ner similar to the effect of the transceiver front-
panel [
FAST
] button.

LARIFIER
You may change the receiving frequency only without changing the transmit frequency.
1. Press the [ CLAR
] button to activate the clarifier.
The “ ” icon will appear on the display.
2. Rotate the [ MAIN DIAL
] knob to tune the desired
receive frequency. (Offset of up to ±9.99 kHz may
be set using the clarifier.)
The offset frequency will appear
at the bottom right corner of the
display.
3. Press the [ CLAR
] button again to disable the clari-
fier. The “ ” icon will disappear from the dis-
play.

Clarifier Offset
When the receiving frequency is
higher than transmit frequency,
“+” will be appended to the off-
set frequency.
When the receiving frequency is
lower than transmit frequency, “–”
will be appended to the offset fre-
quency.
You may assign the CLAR function to the [ DSP/
SEL
] knob via the Menu Item “
CLAR
”.
N
OTE
:
Even when the clarifier is disabled, the variance
of the clarifier remains (both TX and RX frequen-
cies).
Press and hold in the [ CLAR
] button for one sec-
ond to clear the clarifier offset, meaning the re-
ceiving frequency is equal to the transmit fre-
quency.
When the [ MAIN DIAL
] knob is rotated to change
the frequency after disabling the clarifier, the clari-
fier offset becomes “zero”, meaning the receiv-
ing frequency is equal to the transmit frequency.
