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.

2. Important information

Do not drop your hearing system! Dropping onto a

hard surface can damage your hearing system.

Always use new batteries for your hearing system.

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.

The following user instructions describe three hearing

system models: The standard hearing system the micro

hearing system and the CRT hearing system.

The standard hearing system is adapted with a classic

earmould. The micro and CRT hearing system can be

adapted with a variety of earmoulds.

On the following pages use the labeled drawings to

identify the hearing system and the earmould that

you use.

Your audiologist will tell you what size of battery you

need for your hearing system.
