MICROPHONE & AUDIO ISSUES
Q: Why is my microphone audio is low?
A: Here's are some suggestions:
1) Talk directly into the radio, within one inch.
2) Confirm the audio is set to Wide Band. 5 kHz (Menu 5 = W)
3) Try an external spkr/mic to confirm problem is the mic.
4) Blow compressed air into the spkr/mic jack.
5) If you have an external spkr/mic, plug it in and out a few times.
The issue might be a dirty connector.
Note: Some have reported the need to open up the microphone hole in the plastic case.
This can be done by CAREFULLY using a 3/64" drill bit and twisting it slowly by
hand to clear out the opening, but avoid touching the microphone.
There is approx 1/16" clearance between the inside of the case and the microphone
element.
