Please read the information on the following pages
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 benet 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.

or if skin irritation and accelerated accumulations
of ear wax occur, please check with your hearing care
professional or physician.
!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 does get stuck in
your ear canal, it is strongly recommended to see a
medical practitioner for safe removal.

reduce background noises. Please be aware that
warning signals or noises coming from behind, e. g.

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. The
Phonak CROS transmitter is placed on the unaidable ear
and transmitts sounds to the Phonak hearing aid on the
other ear. The sound is transmitted wireless and can be
heard clearly and directly on the hearing ear.
