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.
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.
2. Important safety information

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, mentally challenged
people 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.
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.
This hearing aid is not designed to be used for
children below 36 months. The hearing aid contains
small parts that can cause choking, if swallowed by

2.2 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 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.

2. Important safety information
Always use new batteries for your hearing aid. In case
a battery is leaking, replace it immediately with a
new one to avoid skin irritations. 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 3 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.

11
Special medical or dental examination including
radiation described below, may adversely affect the
correct functioning of your hearing aids. Remove and
keep them outside the examination room/area before
undergoing:
SMedical or dental examination with X-ray (also CT
scan)
SMedical examinations with MRI/NMRI scans,
generating magnetic fields

security gates (airports etc.). If X-ray is used at all, it
will be in very low doses, and will not affect the hearing
aids.
