will appear on the LCD, allowing selection and ad-
justment of the various Menu items.

AF GAIN RF GAIN Knobs
AF GAIN Knob
Clockwise rotation of this control increases the Vol-
ume level. Typically, you will operate with this con-
trol set past the 9 o’clock to 10 o’clock position.
RF GAIN Knob
This is the control that adjusts the gain of the VFO-
A’s RF and IF stages. Clockwise rotation increases
the gain level, and this control typically is left in the
fully clockwise position, which provides maximum re-
ceiver gain.
P.BACK Switch
Press and hold in this button for 2 seconds to activate
the recording feature of the internal Digital Voice Re-
corder. The Voice Recorder allows you to record the
VFO-A audio for the most-recent 30 seconds. While
you’re recording the receiver audio, the LED in this
button glows red.
Press and hold in this button for 2 seconds once more
to stop the recording, then press this button momen-
tarily again to play back the receiver audio for the
most-recent 30 seconds of reception before you
stopped the recording.
While playing back the receiver audio, the LED in-
side button will glow umber.
Press and hold in this button for 2 seconds again to
resume recording.
AFL Switch
Pressing this button activates the Audio (AF) Limiter
circuit of the VFO-B. This will protect the audio am-
plifier from distortion, and protect your ears from high
audio levels, caused by sudden peaks in audio input
when the AGC is set to “OFF.” When the Audio Lim-
iter circuit is activated, the LED inside the button will
glow orange.
