No Sound or Not
Loud Enough
Ensure that the battery door is closed.
Replace the battery.
Make sure the tip/dome is not clogged.
(Refer to page 20 for cleaning instructions.)
Make sure the amplifier case and tubing are
clean and dry.
Make sure that the amplifier case is
positioned properly behind the ear, and that
the tip/dome is positioned properly in the
ear canal.
Make sure the volume is turned up, by
tapping the upper portion of the rocker
switch.
Remove the 9mm dome tip and attach
one of the larger dome tips. Try a vented
dome first, and if still not enough sound, try
a closed dome. Be sure to secure the tip/
dome. See page 12. If feedback continues,
consider changing to an earhook with a
dome.
Excessive ear wax can prevent sound from
entering the ear. Contact your physician.
Changes in your hearing can affect how
you hear with Tweak. Contact a hearing
healthcare professional if you suspect any
change in your hearing condition.
Your Tweak may need to be reset for more
volume. See page 27 for instructions
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/dome is positioned
properly in the ear canal.
Try adjusting the volume. Tap the lower
portion of the rocker switch to decrease
volume.
If already using amplification setting 4
consider using the larger (12mm) vented
dome instead of the 9mm dome. If feedback
continues, consider using one of the closed
domes or change to an earhook with a
dome.
Your Tweak may need to be reset. See
page 27 for instructions. (For example: If
you’re currently on Amplification Setting 4,
consider Amplification Setting 3.)
If the above fails to reduce feedback, call
Tweak Support at 1-888-815-3240.
