The T2000-50 handsfree kit is designed for use with all T2000 Series II mobiles, and
allows communication through the normal PTT microphone, or ‘handsfree’ operation
through a directional microphone.
When ‘handsfree’ operation is being used, the transmitter is activated either by the foot-
switch (Manually Operated Transmit) or automatically, by detecting the sound of a
voice. The latter is known as the Voice Operated Transmit (VOX) mode. VOX operation
is only intended for use in quiet modern vehicles.
With trunked radios, a call needs to be established before VOX or footswitch
becomes operative. Normal handsfree operation can be used on a conventional
channel.
