VOX OPERATION
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 activate VOX and 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.
2 With the transceiver power OFF, press and hold the Side 1
key for 2 seconds while turning the transceiver power ON.
• The LED flashes red and green.
3 Press the Side 1 key to increase the VOX Gain level and
the Side 2 key to decrease the level.
• The VOX Gain can be adjusted from levels 1 to 10 and OFF.
4 While adjusting the gain level, speak into the headset
microphone as you would while under normal operation, to
test the sensitivity level.
• When the microphone recognizes a sound, the LED lights
orange. This allows you to determine a suitable level where
background noise will not activate VOX operation while
speaking into the microphone will.
• The transceiver does not transmit your voice during this test
procedure.
