Charging your hearing aids
We recommend that you fully charge your hearing aids before using them. This is just a precaution to make sure
that you don't run out of power unexpectedly. To learn how to charge your hearing aids, please consult the user
guide for your hearing aid charger.
Battery warnings
WARNING:
•Rechargeable hearing aids are supported by a non-removable rechargeable lithium-ion battery cell.
Exposure or ingestion can be seriously harmful.
•Never put your rechargeable hearing aid in your mouth.
•Keep your rechargeable hearing aid away from pets, children and people with cognitive, intellectual or
mental health challenges.
•Never swallow lithium-ion batteries nor place them inside any part of the body, as this may lead to fatal
injuries in two hours or less. If a lithium-ion battery is swallowed or placed inside any part of the body,
or if a rechargeable hearing aid is swallowed, seek immediate medical attention.
•If the outer casing of your rechargeable hearing aid is broken, the rechargeable batteries inside may
leak. In this case, do not attempt to use the hearing aid – contact your hearing care professional.
•Battery leakage can cause chemical burns. If you get exposed to battery leakage material, rinse
immediately with warm water. If you get chemical burns, redness or skin irritation from battery leakage,
seek medical attention.
Charging your hearing aids 9

•Batteries are harmful for the environment. Therefore, never try to burn them – dispose of your used
rechargeable hearing aids according to your country’s regulations or return them to your hearing care
professional.
•For safety reasons, use only the charger provided with your hearing aid.
•When traveling, consult your airline about any rules for transportation of your hearing aid and charger.
