Please read the information on the following pages
before using your hearing system.
2.1Hazard warnings
Use only hearing systems that have been specially
programmed for you by your hearing care pro-
fessional. Other systems may be ineffective and
may, in certain cases, damage your hearing.
Changes or modifications to the hearing system that
were not explicitly approved by Phonak are not
permitted. Such changes may damage your ear or
the hearing system.
Hearing system batteries are toxic if they are
swallowed! Keep out of reach of children and pets.
If batteries are swallowed, consult your medical
practitioner immediately!
2. Important information
7
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 system contains small parts which can
be swallowed by children.
External devices may only be connected if they have
been tested in accordance with corresponding IEC
standards. Only use accessories approved by
Phonak AG.
2.2 Information on product safety
Never immerse your hearing system in water!
Protect it from excessive moisture. Always remove
your hearing system before showering, bathing,
or swimming.
8
Protect your hearing system from the heat (never
leave it near a window or in the car.) Never use
a microwave or other heating devices to dry your
hearing system. Ask your audiologist about suitable
drying methods.
When you are not using your hearing system, leave
the battery compartment open so that any moisture
can evaporate. Make sure that you always completely
dry your hearing system after use. Store the hearing
system in a safe, dry and clean place.
Do not drop your hearing system! Dropping onto a
hard surface can damage your hearing system.
Always use new batteries for your hearing system.
Your audiology department can advise you on where
old batteries should be disposed of.
2. Important information

Remove the battery if you are not using your hearing
system for a long period of time.
X-ray radiation (e. g. CT scans, MRI scans) may
adversely affect the correct functioning of your
hearing systems. We recommend that you remove
them before undergoing X-ray procedures and
keep them outside the room.
Do not use your hearing system in areas where
electronic equipment is prohibited.
