might swallow these items
Discard batteries safely. Keep discarded
batteries out of sight of infants, small children,
vulnerable persons, and pets.
Clean your hearing aid (including parts) on a
regular basis, as recommended by your hearing
care professional. Microorganisms from an
unclean hearing aid may cause skin irritations.

of the hearing aid, in front of infants, small
children, and vulnerable persons
Be aware of the possibility that your hearing aid
may stop working without notice. Keep this in
mind when you depend on warning sounds
(e.g., when you are in trafc).
Be aware of the possibility that the directional
microphone in your hearing aid may reduce the
volume of some warning sounds coming from
behind you
Remove your hearing aid before applying
aftershave, hairspray, oils, perfume, mosquito
repellent, lotions, etc. If your hearing aid is
exposed to such a product, allow the product to
dry before you put your hearing aid on.

Warnings to Hearing Care Professionals
and Users
Take special care when tting and using a
hearing aid with maximum sound pressure
capability in excess of a maximum of 132 dB SPL
(IEC 60318-4). In this case, there may be a risk
of damaging the hearing aid user’s hearing.
Only connect hearing aids with Direct Audio
Input (DAI) to electrically powered devices
that comply with EN 60601-1-1, EN 60065 or
equivalent safety standards. The external signal
source determines the safety of hearing aids
with DAI.

Step 3a: Inserting Your Hearing Aid with an
Earmold
·When inserting the right earmold, hold it with the
right hand. When inserting the left earmold, hold it
with the left hand.
·Hold the earmold so that the canal part is pointing
at the ear canal entrance and the frame of the
earmold is pointing straight up
·Insert the canal part into the ear canal aiming
slightly up and back, not straight into the ear.
Then twist back slightly to press the frame of the
earmold into the hollow part of the ear.

20
·Run your nger down the skin just in front of your
ear. If you feel any plastic parts of the earmold, it is
not inserted correctly. Gently push the plastic back
and behind the top fold of your ear. The earmold
should seal into all folds of the ear.
·Then tuck the hearing aid over/behind your ear,
making sure that the tubing is not twisted
