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 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
batteries are swallowed, consult your physician
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.

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.
