VOICE OPERATED TRANSMISSION (VDX)

VDX operation allows you to transmit hands-free. This feature must first be 
activated by your dealer and can only be used if you are using a supported 
headset.
When operating VDX, you must set a VDX 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 VDX Gain level to an appropriated sensitivity to allow smooth 
transmission.
To activate VDX and set the VDX Gain level, perform the following steps:

1. Connect the headset to the 
transceiver (page 4)

The VDX 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 while 

tuning the transceiver power ON.

3. Continue to hold the 

Side 1

 key until 

a beep sounds.

The LED indicator lights orange.

When the 

Side 1

 key is released the 

transceiver announces the VDX Gain 
level

4. Press the 

Side 1

 key to increase the 

VDX Gain level and the 

Side 2

 key to 

decrease the level

The VDX Gain can be adjusted from 
levels 1-10 and OFF

The transceiver announces the VDX 
Gain level as you adjust it. If OFF is 
selected, a beep sounds

5. Press the 

PTT

 switch to save the 

setting

A beep will sound.

The transceiver announces the new 
VDX Gain level.
