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 benet 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.
2.1 Hazard 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

7
! Do not use the hearing aids in explosive areas (mines
or industrial areas with danger of explosions).
! Phonak CROS system batteries are toxic if they are
swallowed! Keep out of reach of children and
mentally challenged people or 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.
! 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.
! 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 hearing aid contains small parts that can cause
choking, if swallowed by children. Keep out of reach
of children and mentally challenged people or pets.
If swallowed, consult a physician or hospital
immediately.
! External devices may only be connected if they have
been tested in accordance with corresponding
IECXXXXX standards. Only use accessories approved
by Phonak AG, to avoid any electrical shock.

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.
Phonak CROS transmitter + Phonak hearing aid =
