TETRA Tip: If your TETRA device is
in the ear and the device whistles,
then something is not correct.
Check the following: 1. Make sure
your ear canal is not blocked with
wax. 2. Make sure the tip is not too
worn or too small. 3. Make sure
the TETRA device is fully seated in
the canal.
TETRA Tip: To check tip fit, hum
or talk with the devices in place.
Your voice should sound noticeably
louder with a proper occluded fit.
