Whistling (“feedback”)
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 the
volume.
Your Tweak may need to be reset. See page 28 for instructions. Once reset, repeat
steps on page 16 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.
Sound is Distorted, Unclear, Intermittent or has Static Noise
Replace the battery.
Make sure the tube and tip are not clogged. (Refer to page 21.)
Make sure the amplifier is clean and dry. We recommend nightly use of a TweakDry UV
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.
Your Tweak may need to be reset. See page 28 for instructions. Once reset, repeat
