VOICE OPERATED TRANSMISSION (VOX)
VOX can be activated or deactivated by your dealer. VOX
operation allows you to transmit hands-free. This feature can
only be used if you are using a supported headset.
When operating VOX, you must set a VOX Gain level. This
setting allows the transceiver to recognize sound levels. If the
microphone is too sensitive, it will begin transmitting when
there is noise in the background. If it is not sensitive enough,
it will not pick up your voice when you begin speaking. Be
sure to adjust the VOX Gain level to an appropriate sensitivity
to allow smooth transmission.
To set the VOX Gain level, perform the following steps:
1 Connect the headset to the transceiver.
• The VOX function does not activate when a headset is not
connected to the accessory terminal of the transceiver.
