8. Press the [ MODE ] button to select the desired oper-
ating mode.
Repeated presses of the [ MODE ]
button step through the available se-
lections.
Pressing and holding the [ MODE ]
button will toggle to the alternate mode.
For example, In the LSB or USB modes, pressing
and holding the [ MODE ] button toggles between
"LSB" and "USB" mode.

 By convention in the Amateur bands, LSB is
used on the 7 MHz and lower bands (with the
exception of 60 meters), while USB is utilized on
the 14 MHz and higher bands.
 When changing modes from SSB to CW, you
will observe a frequency shift on the display.
This shift represents the BFO offset between the
"zero beat" frequency and the audible CW pitch
(tone) you can hear (the pitch is programmed via
the Menu item "064 CW FREQ DISPLAY"),
though the actual tone that you hear is not chang-
ing.
 When operating on the FM mode, rotate the [ RF/
SQL ] (Squelch) knob clockwise to the point
where the background noise is just silenced. This
is the point of maximum sensitivity to weak sig-
nals. Excessive advancement of the [ RF/SQL ]
knob will decrease the ability of the receiver to
detect weak signals.
You may switch the [ RF/SQL ] knob from the RF
Gain Function to the Squelch Function via Menu
item "036 RF/SQL
VR".

9. Rotate the Main Tuning Dial knob to tune around the
band, and begin normal operation.

 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
even
engages the "Fast" tuning selection (see chart be-
low).
 The tuning steps for the Main Tuning Dial knob
are set, at the factory, to 10 Hz (SSB, CW), 50
Hz (RTTY/DATA) and 100 Hz (AM/FM) per
step. Via Menu items "151 CW DIAL STEP"
to "155 SSB DIAL STEP", however, you may
change these settings from 10 Hz to 1 or 5 Hz
(SSB, CW), 5 Hz to 1 or 10 Hz (RTTY, DATA),
100 Hz to 10 Hz (AM, FM) instead.

 If you want to effect rapid frequency
there are several techniques available:
 Direct keyboard entry of the frequency.
 Use the [ CLAR/VFO-B ] knob to tune in 1
 Use the microphone's [ UP ] / [ DWN ] scanning
