Top Pane Access & Contro
The following controls are accessible beneath
the removable panel on the top half of the trans-
ceiver case. Push the slide rearward and pry up
the lid to expose the AbC UNIT circuit board and
potentiometer controls. Most control settings are
preset at the factory for normal operation. Should
you desire to change a particular setting, use a
small insulated screwdriver to rotate the desired
potentiometer.

HPA-M
This control sets the audio level available from
the main receiver to headphone jack A (3.5 mm
plug).
(2)

A-VOX
(ANTI-VOX TRIP)
This control sets the level of negative feedback
of receiver audio to the microphone, to prevent
receiver audio from activating the transmitter (via
the microphone) during VOX operation. Adjust-
ment is described in the Operation chapter.
(9)
DLAY
(VOX Delay)
This control sets the hang time of the VOX\
circuit, between the moment you stop speaking
(or open the CW key during semi break-in opera-
tion) and the automatic switch from transmit back
to receive (during VOX operation). Adjust for
smooth VOX or semi break-in operation (so the
receiver is activated only
J1
when you want to listen).

This control sets the gain of the VOX (voice-ac-
i
tuated 'transmitlreceive switching) circuit, to set
the level of microphone audio needed to activate

VQX
button on the front panel is depressed.

FM MIC
During FM operation, this control adjusts the
microphone gain (and transmitter deviation).
More clockwise settings produce a wider band-
width signal.
NOTE: This control has been preset at the
factory to produce the correct deviation with
standard microphone levels. A deviation meter
should be connected for proper readjustment, as
it is difficult to determine the proper setting by ear.
