12 i Care and maintenance
Please follow the instructions below to have the best user experience and to prolong the durability of
your hearing aids:
1. Keep your hearing aid clean and dry. Wipe the case with a soft cloth or tissue after use to remove
grease or moisture. Do not use water or solvents, as these can damage the hearing aid(s).
2. Never immerse hearing aids in water or other liquids, as liquids may cause permanent damage to
the hearing aids.
3. Avoid rough handling of hearing aids or dropping them on hard surfaces or floors.
4. Do not leave hearing aids in or near direct heat or sunlight, such as in a hot, parked car, as exces-
sive heat can cause damage or deform the casing.
5. Do not wear your hearing aid while showering, swimming, in heavy rain or in a moist atmosphere
such as a steam bath or sauna.
6. If your hearing aid does get wet, or if it has been exposed to high humidity or perspiration, it
should be left to dry out overnight with the battery out and the battery door open. It is also a
good idea to put the hearing aid and battery in a sealed container together with a drying agent
(desiccator) overnight. Do not use the aid until it is completely dry. Consult your hearing care
professional as to which drying agent to use.
7. Remove your hearing aid when applying cosmetics, perfume, aftershave, hair spray, and suntan
lotion. These might get into the aid and cause damage.
12.1 i Daily maintenance
It is important to keep your hearing aid clean and dry. On a daily basis, clean the hearing aids using a soft
cloth or tissue. In order to avoid damage due to humidity or excessive perspiration, the use of a drying kit
is recommended.
12.2 Replacing wax filters
Custom hearing aids may have wax filters that protect against wax and moisture. It is recommended that
these are changed as needed.
