before using your Phonak CROS system

A Phonak CROS system will not restore normal hearing

and will not prevent or improve a hearing impairment

resulting from organic conditions. Infrequent use of a

Phonak CROS system does not permit a user to attain

full beneﬁt from it. The use of a Phonak CROS system is

only part of hearing habilitation and may need to be

supplemented by auditory training and instruction in

lipreading.

2.1Hazard warnings

Use only Phonak CROS systems that have been

specially programmed for you by your hearing care

professional. Other systems may be ineffective

and may, in certain cases, damage your hearing.

Changes or modiﬁcations to the Phonak CROS system

that were not explicitly approved by Phonak are

not permitted. Such changes may damage your ear

or the hearing system.

2. Important safety information

Phonak CROS system batteries are toxic if they are

swallowed! Keep out of reach of children and pets. If

immediately!

If you feel pain in or behind your ear, if it is inﬂammed

or if skin irritation and 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.

The Phonak CROS 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

IECXXXXX standards. Only use accessories approved

The Phonak CROS system is a hearing application for

unilateral hearing loss to compensate the head shadow

effect for sounds originating on the unaidable side.

on the other ear. The sound is transmitted wireless and

can be heard clearly and directly on the hearing ear.
