15.2 Information on product safety
Never immerse your hearing
aid in water! Protect it from
excessive moisture. Always
remove your hearing aid
before showering, bathing,
or swimming, as the hearing
aid contains sensitive
electronic parts.

Protect your hearing aid
from heat (never leave near
a window or in the car).
Never use a microwave
or other heating devices
to dry your hearing aid.
Ask your hearing care
professional about suitable
drying methods.
When you are not using
your hearing aid, leave the
battery door open so that
any moisture can evaporate.
Make sure that you always
completely dry your
hearing aid after use. Store
the hearing aid in a safe,
dry and clean place.
Do not drop your hearing
aid! Dropping onto a hard
surface can damage your
hearing aid.
Always use new batteries
for your hearing aid. In
case a battery is leaking,
replace it immediately
with a new one to avoid
any skin irritation. You
can return used batteries
to your hearing care
professional.
The batteries used in these
hearing aids should not
exceed 1.5 Volts. Please do
not use silver-zinc or Li-ion
(lithium-ion) rechargeable
batteries as these may
cause severe damage to
your hearing aids. The
table in chapter 5 explains
exactly which type of
battery your particular
hearing aids require.
Remove the battery if
you are not using your
hearing aid for a long
period of time.
