The pictures below show the models described in this user
guide. You can identify your personal model by:
• Checking “Your CROS device” on page 3.
• Or comparing your CROS device with the following
shown models. Pay attention to the shape of the CROS
device and if a volume control is present.
The Phonak CROS device is an application for single-
sided deafness, one-sided hearing loss or asymmetrical
hearing loss. It is placed on the impaired ear and
wirelessly transmits sound to the Phonak hearing aid
on the other ear.

The intended use of a
CROS device is to transmit
sound to a hearing aid on
the better hearing ear and
hereby compensate for
impaired hearing. The
CROS system (specially
programmed for each
hearing loss) must only
be used by the intended
person. They should not
be used by any other
person as they could
damage hearing.
Changes or modications
to the CROS device that
were not explicitly approved
by Phonak are not permitted.
Such changes may damage
your ear or the CROS device.
Do not use the CROS
device in explosive areas
(mines or industrial areas
with danger of explosions,
oxygen rich environments
or areas where ammable
anesthetics are handled).
Hearing aid batteries are
toxic if they are swallowed!
Keep out of reach of children
under 3 years. If batteries
are swallowed, consult your
physician immediately!
If you feel pain in or behind
your ear, if it is inamed or if
skin irritation and accelerated
accumulations of earwax
occur, please check with
your hearing care
professional or physician.
15.1 Hazard warnings
32
Please read the information on the following pages before
using your CROS device.
A CROS device will not restore normal hearing and will not
prevent or improve a hearing impairment resulting from
organic conditions. Infrequent use of a CROS device does
not permit a user to attain full benet from it. The use of
a CROS device is only part of hearing habilitation and may
need to be supplemented by auditory training and
instruction in lipreading.
15. Important safety information

35
the manufacturer of the
active implant. Please, note
that interference can also
be caused by power lines,
electrostatic discharge,
airport metal detectors etc.
Keep magnets (i.e. battery
handling tool, EasyPhone
magnet, etc.) at least
15 cm (6 inches) away
from the active implant.
34
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 CROS device is not for
children below 36 months.
It contains small parts that
can cause choking, if
swallowed by children.
Keep out of reach of
children under 3 years.
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 following is only
applicable for persons with
active implantable medical
devices (i.e. pacemakers,
debrillators, etc.):
Keep the wireless hearing
aid or CROS device at least
15 cm (6 inches) away
from the active implant.
If you experience any
interference, do not use the
wireless hearing aids or
CROS device and contact

37
Do not drop your CROS
device! Dropping onto a
hard surface can damage
your CROS device.
Always use new batteries
for your CROS device. In
case a battery is leaking,
replace it immediately
with a new one to avoid
any skin irritation. You
can return used batteries
to your hearing care
professional.
The batteries used in the
CROS device should not
exceed 1.5 Volts. Please do
not use silver-zinc or Li-ion
(lithium-ion) rechargeable
batteries as these may
cause severe damage to
your CROS device. The
table in chapter 5 explains
exactly which type of
battery your particular
CROS device requires.
Remove the battery if
you are not using your
CROS device for a long
period of time.
36
Never immerse your CROS
device in water! Protect it
from excessive moisture.
Always remove your CROS
device before showering,
bathing, or swimming, as
the CROS device contains
sensitive electronic parts.
15.2 Information on product safety
Protect your CROS device
from heat (never leave near
a window or in the car).
Never use a microwave
or other heating devices
to dry your CROS device.
Ask your hearing care
professional about suitable
drying methods.
When you are not using
your CROS device, leave
the battery door open so
that any moisture can
evaporate. Make sure that
you always completely dry
your CROS device after use.
Store the CROS device in a
safe, dry and clean place.

Some hearing aid users have reported a buzzing sound
in their hearing aids when they are using cell phones.
According to the ANSI 63.19 (American National
Standard Methods of Measurement of Compatibility
between Wireless Communications Devices and Hearing
Instruments) standard, the compatibility of a particular
hearing aid and cell phone can be predicted by adding
the rating for the hearing aid immunity to the rating for
the cell phone emissions. The sum of the hearing aid
rating (e.g. M2/T2=2) and the telephone rating
(e.g. M3/T3=3) is 5, and any combination that equals
5 will provide “normal use”; a sum of 6 or greater would
indicate “excellent performance”. The equipment
performance measurements, categories and system
classications are based upon the best information
available but cannot guarantee that all users will be
satised. The immunity of this hearing aid is at least
M2/T2.

Special medical or dental
examination including
radiation described below,
may adversely aect the
correct functioning of your
CROS device. Remove and
keep them outside the
examination room/area
before undergoing:
Medical or dental
examination with X-ray
(also CT scan).
Medical examinations with
MRI/NMRI scans, generating
magnetic elds.
CROS devices don’t need to
be removed when passing
security gates (airports
etc.). If X-ray is used at all,
it will be in very low doses,
and will not aect the
CROS devices.
Do not use your CROS
device in areas where
electronic equipment
is prohibited.
