the lip microphone is made more or less sensitive to activation via the user’s voice and/or surrounding
noise levels.
Tip(s):
1) Press (+) as the noise becomes louder (therefore making the microphone less sensitive to outside
noise) and viceversa as noise levels drop.
2) Setting 1 is for low noise applications. Setting 5 is for extreme noise applications. Try different
settings until the optimum setting is found.
3) Setting 1 requires minimal voice level to activate the microphone. Setting 5 requires maximum voice
level to activate the microphone.
4) Do not pause when talking during transmissions, VOX will turn off during pauses
5) Ensure lip microphone is no more than 5mm away from the mouth.
