1. The operating mode is selected using the [MODE]
buttons to the left of the Main Tuning Dial knob, and
the VFO (A or B) to which the selection is applied is
selected by the [A] or [B] button above the [MODE]
buttons. Usually, the [A] button glows Red, signifying
that the Main band (VFO-A) is be-
ing adjusted. Similarly, pressing the
[B] button will cause its indicator to
blink Orange for five seconds, sig-
nifying Sub band (VFO-B) adjust-
ment. Therefore, press the [A] or [B]
button to select the desired VFO,
then press the [LSB] or [USB] but-
ton to select one of the SSB modes.
For AM operation, press the [AM/
FM] button repeatedly until the im-
bedded LED glows red.

4. In the SSB mode, adjust the microphone amplifier gain
to match the microphone and your
voice level, set the [METER]
switch to the “ALC” position,
close the PTT switch, speak into
the microphone in a normal voice
level, and adjust the [MIC] (gain) knob
so that the ALC voltage (displayed on
the right meter) stays within the ALC
zone of the meter (up to 2/3 of full scale
deflection) on voice peaks.

The microphone
ga in of the A M
mode has been pro-
grammed, at the
factory, to a level
that should be satisfactory for most situations. How-
ever, using Menu item “050 A3E MICGAIN,” you may
set a different fixed value, or choose the “Ur” option,
which then lets you use the front panel [MIC] knob to
set the microphone gain in the AM mode. In this case,
the [MIC] knob should not be advanced to the point
where the ALC meter deflects. In many cases, the same
setting as used on SSB will be satisfactory.
