VOX DESCRIPTION
The VOX system on your new ChatterBox® enables the microphone to be
voice activated. This means that when you speak the microphone will open
automatically and transmit your voice. It is best to think of the VOX as the
microphone sensitivity setting.
Turn the power switch to on. If you turn the VOX sensitivity dial clockwise
and speak through the microphone, the VOX operates and automatically trans-
mits. You will know you are transmitting when you hear yourself in the head-
set speakers. Operation is totally automatic, no external controls are required.
To receive, just listen in silence. If your mic is activated, you cannot receive.
Simultaneous transmission is not possible. You cannot talk (activate your
VOX) and hear a transmission from another ChatterBox at the same time.
VOX FUNCTION
The VOX adjustment knob on the front of your ChatterBox® is the single most
important control on the unit. When set on “Hi” (high) the microphone will
easily pick up a normal speaking voice. Never begin riding with the VOX set
on “Hi”. This will cause the microphone to constantly open and thus prevent
proper communications.
When set between the “Hi” (high) and “Lo” (low) the microphone sensitivity is
reduced thus requiring a louder voice to activate. This is necessary to prevent
the microphone from opening due to wind noise or loud exhaust systems, both
of which can prematurely open the microphone. When the microphone opens
prematurely the channel is held open which causes a hissing noise in every-
body’s headset and prevents users from communicating. This is a situation
many first time users experience while learning to properly adjust the VOX.
(To eliminate this situation, it is strongly recommended that first time users use
a PTT “push to talk” button.) At the full “Lo” (low) setting the microphone is
actually shut off so no transmission is possible.
HOW TO TRANSMIT AND RECEIVE
VOX ADJUSTMENT PRACTICE
It is highly suggested that each new user practice adjusting their radio before
riding. It’s simple, quick and effective.
A. With the helmet off, turn the VOX knob to the “Hi” (high) sensitivity
position.
B. Place the helmet on your head (with the ChatterBox® fully installed).
C. Speak into the microphone in a normal voice. You should hear your voice
in the speakers. Adjust the volume to a comfortable setting. If you don’t
hear anything turn the volume up. If you still don’t hear anything check
all the wire connections and make sure the VOX is set to the full “Hi”
position.
D. Next, continue to speak while turning the VOX knob towards the “Lo”
setting. As you do this you’ll notice that you must speak louder to activate
the microphone.
E. When the knob is turned almost to “Lo”, you’ll find that you must talk
very loud to activate the microphone. This is where the VOX must be set
during high speed riding or in very loud wind condi-
tions.
F. Next, turn the VOX knob to the full ”Lo” position.
When the VOX is set at this position the microphone is
off and no transmitting is possible.
It is highly suggested that you always begin your rides with
the VOX set close to the full “Lo” setting. Once under way you can then fine
tune the sensitivity.
