Clean the dome with the wax pick
Make sure the pick is clean.
Pick the built-up wax off the
exterior of the dome. Check
between the spokes of the
dome as well for build-up.
Clean the tube and dome
Remove the tube from the earpiece. Find the part of
the tube that attaches to the earpiece. Gently rotate
this section of the tube so that the sound inlet is
exposed (as shown here).

Once you've removed the tube from the earpiece, use
a soft, moist cloth or mild soap and water to clean
the tube and dome.
If you find larger build-up of wax in certain areas,
such as on the dome or one of the ends of the tube,
use the wax pick to remove the build-up. The pick is
integrated into the handle of the brush included with
the charger.
You can also use the AR PSA accessory cleaning kit,
available through ARHearBetter.com or through the
accessories brochure in this package.
IMPORTANT: Make sure all components are completely dry
before you put them back on the earpiece.
If there's wax in the tube: Use a section of
monofilament fishing line (medium to heavy-gauge)
to clean inside the tube. You can also use the tube-
cleaning rod from the AR PSA cleaning kit, available
from the accessories brochure in this package or on
ARHearBetter.com.

IMPORTANT: DO NOT pull the
tube off at an angle. Doing so
could harm the tube or the
components in your earpiece
and void your warranty.
Clean the microphone and sound inlet
The microphone and sound inlet
on your earpiece are under the
tube connector. To clean these
parts, you must first remove
the tube from the earpiece (see
Cleaning the tube and dome on
the previous page).
Once you've removed the tube
from the earpiece, use the
cleaning brush to gently remove
any particles that may be on the
earpiece's microphone or sound
inlet (shown here). DO NOT use
any liquids or solvents on the
earpiece.
Replace the dome
To remove the dome, hold the end
of the tube between your thumb
and forefinger and pull the dome
off with your other hand.
If you need to order a replacement
dome, use the accessory brochure
included in this package or visit
ARHearBetter.com. To mount the
new dome to the earpiece tube,
push the opening on the back of
the dome gently onto the end of the
tube. Push the dome onto the end
of the tube as far as it will go. Make
sure the dome is securely fastened.
IMPORTANT: The dome attached to the wide
tube works with the wide tube only. Do not try
to use it with one of the thin tubes.
