How to Transmit and Receive
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 clock-
wise and speak through the microphone, the VOX operates and automati-
cally transmits. You will know you are transmitting when you hear your-
self in the headset 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 micro-
phone 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 sensitiv-
ity 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 everybody’s headset and prevents users from communicat-
ing. This is a situation many first time users experience while learning to
properly adjust the VOX. (To eliminate this situation, it is strongly recom-
mended 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 transmition is
possible.
