This item adjusts the VOX gain for the VOX func-
tion. Higher values make the VOX function more 
sensitive to your voice.

While speaking into the microphone with your nor-
mal voice level, rotate the main dial to the point 
where the transceiver is continuously transmitting.

This setting can be adjusted from 0% to 100% in 1%
steps.

This item adjusts the ANTI-VOX gain for the VOX 
function. Higher values make the VOX function less 
sensitive to receiver output audio from a speaker or 
headphones.

During receive, rotate the main dial to the point 
where the transceiver does not switch to transmit 
due to received audio from the speaker.

This setting can be adjusted from 0% to 100% in 1%
steps.

Set the VOX delay for a convenient interval before 
returning to receive within 0.0 to 2.0 sec. range.

Set the VOX voice delay to prevent clipping of the 
first few syllables of a transmission when switching 
to transmit.
OFF, Short, Mid and Long settings are available.

 When using the VOX voice delay, turn the TX 
monitor function OFF to prevent transmitted audio 
from be echoed.
