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 audiologist. Other sy-
stems 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 doctor
immediately!
2. Important information
Your Audiology Department will advise you on
where old batteries should be disposed of.

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 remains in
your ear canal, it is strongly recommended to see a
doctor 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.
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.
Protect your hearing system from heat (never leave
it near a window or in the car.) Never use a micro-
wave 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.

Always use new batteries for your hearing system.
Remove the battery if you are not using your hearing

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.
