Operating Manual
Basic Operation: Receiving on Amateur Bands
7. Rotate the Main Tuning Dial knob to tune around the
band, and begin normal operation.
Advice:
Clockwise rotation of the Main Tuning Dial knob
increases the operating frequency, one “step”
of the synthesizer at a time; similarly, counter-
clockwise rotation of the Main Tuning Dial knob
will decrease the frequency. Two settings, one
“normal” and one “fast”, are available for each
operating mode. Pressing the
FAST
button en-
gages the “Fast” tuning selection (see chart be-
low).
