Please read the information on the following pages
before using your hearing aid.
A hearing aid will not restore normal hearing and
will not prevent or improve a hearing impairment
resulting from organic conditions. Infrequent use
of a hearing aid does not permit a user to attain full
benefit from it. The use of a hearing aid is only
part of hearing habilitation and may need to be
supplemented by auditory training and instruction
in lipreading.
2.1 Hazard warnings
The intended use of hearing aids is to amplify and
transmit sound to the ears and hereby compensate
for impaired hearing. The hearing aids (specially
programmed for each hearing loss) must only be
used by the intended person. They should not be
used by any other person as they could damage
hearing.
2. Important safety information

Changes or modifications to the hearing aid that
were not explicitly approved by Phonak are not
permitted. Such changes may damage your ear or
the hearing aid.
Do not use the hearing aids in explosive areas (mines
or industrial areas with danger of explosions).
Hearing aid batteries are toxic if they are swallowed!
Keep out of reach of children and mentally challenged
people or pets. If batteries are swallowed, consult
your physician immediately!
If you feel pain in or behind your ear, if it is inflamed,
if skin irritation or accelerated accumulations of
ear wax occur, please check with your hearing care
professional or physician.
In very rare cases, the dome can remain in your ear
canal when removing the hearing tube from the
ear. In the unlikely case that the dome does get stuck
in your ear canal, it is strongly recommended to
see a physician for safe removal.

Hearing programs in the directional microphone
mode reduce background noises. Please be aware
that warning signals or noises coming from behind,
e. g. cars, are partially or entirely suppressed.

children below 36 months. The hearing aid contains
small parts that can cause choking, if swallowed
by children. Keep out of reach of children and
mentally challenged people or pets. If swallowed,
consult a physician or hospital immediately.

2. Important safety information
For your micro and micro W hearing aid only:
Your hearing aid is resistant to water, sweat and
dust under the conditions listed in chapter 5. After
exposure to any of these elements the hearing aid
must be cleaned and dried, as the hearing aid
contains sensitive electronic parts.
Never wash the microphone inputs. Doing so could
cause it to lose its special acoustic features.
Protect your hearing aid from heat (never leave it
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 compartment 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.

surface can damage your hearing aid.
Always use new batteries for your hearing aid.
In case a battery is leaking, replace it immediately

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
