For information on obtaining more wax guards contact your hearing care professional to ensure you get
the correct wax guards for your hearing aids.
CAUTION: Use only original consumables from the manufacturer e.g. wax guards.
Replacement of the filter ring
The push button is surrounded by a replaceable filter ring. See "Getting to know your hearing aid", page 8.
The filter ring is to be replaced at regular intervals. If you think your filter ring needs replacement, e.g. because
the sound quality has deteriorated, please consult your hearing care professional.
Storing your rechargeable hearing aids
When not in use, place your hearing aids in the plugged-in charger and charge them, so they are ready for use
when you need them.
If the hearing aids are not to be used for some time, place them in the charger while it is plugged into a power
outlet. Then remove the charger from the power outlet. Both the charger and the hearing aids will turn off.
If you don't want to store the hearing aids in the charger, you can also just turn them off manually.
