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.
2.1Hazard warnings
Use only hearing aids that have been specially pro-
grammed for you by your hearing care professional.
Other hearing aids may be ineffective and may, in
certain cases, damage your hearing.
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.

Hearing aid batteries are toxic if they are swallowed!
Keep out of reach of children and 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.
The hearing aid contains small parts which can be
swallowed by children.

External devices may only be connected if they
have been tested in accordance with corresponding
IECXXXXX standards. Only use accessories approved
by Phonak AG.
2.2 Information on product safety
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 rinsed in fresh water and dried.
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.

Do not drop your hearing aid! Dropping onto a hard
surface can damage your hearing aid.
Always use new batteries for your hearing aid.
You can return used batteries to your hearing care
professional.
Remove the battery if you are not using your hearing
aid for a long period of time.
X-ray radiation (e. g. CT scans, MRI scans) may
adversely affect the correct functioning of your
hearing aids. We recommend that you remove
them before undergoing X-ray procedures and
keep them outside the room.
Do not use your hearing aid in areas where electronic
equipment is prohibited.
