Caring for your hearing aids
Protecting your hearing aids
•
Diligent and routine care of your hearing aids
contribute to outstanding performance and
a long service life. To ensure a long service
life, Sonova AG provides a minimum of a five
year service period after phase out of the
respective hearing aid.
•
Open the battery doors when not in use.
•
Always remove your hearing aids when
using hair care products. The hearing aids
can become clogged and cease to function
properly.
•
Do not wear your hearing aids in the bath or
shower or immerse them in water.
•
If your hearing aids do become wet, do not
attempt to dry them in an oven or microwave.
Do not adjust any controls. Open the battery
doors immediately, remove the batteries and
allow your hearing aids to dry naturally for
24 hours.
