Troubleshooting Sound is distorted or intermittent.
• Trapped moisture may be distorting
the sound. Consider using a hearing
aid dehumidifier overnight.
• Lower the volume.
• Replace the battery with a fresh one
(see page 5).
• Remove tubing from AMP body
(see page 14) and rotate volume dial
to four (4). If it whistles, your AMP is
working and wax or debris may be
blocking the sound.
• Clean tubing/tip (see page 11) and
ear canal. Replace tubing/tip if they
appear worn.
For optimal performance, tubing and tips should be replaced every three
(3) months. To order replacements and additional cleaning accessories,

Device has a weak or no sound.

Device makes a whistling sound.
• Whistling (feedback) occurs when
amplified sound returns to the
microphone and is re-amplified.
• Most amplifiers whistle when not
inserted properly. Try reinserting the
ComfortTIP™into your ear canal so it
fits better.
• Lower the volume.
• If whistling occurs when raising the
volume, you might need more gain
and should try our closed ComfortTIP.
Call us at 800-823-9819.
• Wax or debris can cause whistling.
Clean tubing/tip and ear canal, and
replace tubing/tip if they appear worn.
Please note: When an object (hand, hood, person, wall, etc.) comes close to your
ear while wearing amplifiers, you may experience whistling. This is normal for all
microphones, not just microphones in amplifiers.
