Turn the VOX switch on the front panel to the ON (down) position.
Leaving the T/R
switch in the receive position and without pushing the PTT switch, turn the VOX gain
control clockwise while speaking into the microphone.
At a certain point, the T/R
switching circuit will be activated by your voice.
This is the proper position for the
VOX gain control.
Set the VOX Gain control at a level which provides for T/R switch-
ing at your normal voice level.
Transmit-release time (the time delay before the set
automatically returns to receive when you stop talking) is controlled by the VOX delay
control.
Turning the control counter-clockwise makes the time shorter.
Set it at a
position which is comfortable and which allows for short pauses in normal speech.
Adjust the ANTI VOX control so that the VOX circuit is not activated by sounds from
the speaker by turning the control clockwise while receiving a signal.
