Troubleshooting Tips
Whistling
("Feedback")
24 Troubleshooting Tips
Your Tweak has a best-in-class feedback management
system. However, when your hand is near the device,
you may hear a whistling noise, which is called
"feedback." This may be caused by amplified sound
bouncing off your hand back into the instrument. The
noise usually quits when you take your hand away.
If the whistling doesn't stop once you've moved
your hand away, ensure that the amplifier case is
positioned properly behind the ear, and that the tip is
positioned properly in the ear canal.
Try adjusting the volume. Tap the lower portion of the
rocker switch to decrease volume.
Your Tweak may need to be reset. See page 26
for instructions. Once reset, repeat steps on page
12 (Basic model) or page 14 (Focus model) and
choose a lower Amplification Setting. (Example: If
you're currently on Amplification Setting 3, consider
Amplification Setting 2.)
If the above fails to reduce feedback, contact your
place of purchase.

Replace the battery.
Make sure the tube and tip are not clogged.
(Refer to page 19.)
Make sure the amplifier is clean and dry. We
recommend nightly use of a Dry & Store appliance to
remove moisture and prevent corrosion.
If you are near an electromagnetic field (e.g. near a
computer screen or fluorescent lights), step away to
see if the static clears.
