To use the VOX feature with an external microphone, make sure the PTT/VOX switch is switched
to “VOX” before the radio is powered on and the VOX feature is enabled.
The VOX feature will be enabled for all the channels.
The VOX feature settings will not remain unchanged when the radio is powered on and off.
After the VOX feature is enabled, switching the PTT/VOX switch to “PTT” will disable the feature.
In such case, switching the PTT/VOX switch to “VOX” will keep the radio transmitting. To make
the radio function properly, reattach the earpiece to enable the feature again.
Operation
Activating or deactivating the VOX feature
Go to “Menu -> Setting -> Radio Set -> VOX” to enable or disable this feature.
Press the programmed
VOX
key.
Adjusting the VOX Gain Level
Go to “Menu -> Settings -> Radio Set -> VOX -> Gain Level” to adjust the transmission sensitivity.
Higher gain level can bring lower sensitivity and thus larger voice volume.
Note
Please adjust the VOX Gain Level properly to avoid unexpected VOX triggering due to high
sensitivity or triggering failure due to low sensitivity.
