NOTE
In addition to these user instructions, a separate user manual is
provided describing the various ear-set solutions available for
your transmitter.
WARNING
This booklet and the manual “Ear-sets for Widex BTE hearing
aids” contain important information and instructions. Read
these booklets carefully before you start using the transmitter.
NOTE
Your transmitter and ear-set may not look exactly as illustrated
in this booklet. We also reserve the right to make any changes
considered necessary.
Intended use
The transmitter is intended for use as a device that
picks up sound at the ear on which it is worn and trans-
mits it to a hearing aid on the better ear.

6
Indications for use
The WIDEX CROS solution is indicated for individuals
who are deaf in one ear and have normal or impaired
hearing in the other.
It is to be programmed by licensed hearing care profes-
sionals (audiologists, hearing aid specialists, otolaryn-
gologists) who are trained in hearing (re)habilitation.
Description of device
The transmitter is worn on the deaf ear like an ordinary
“behind-the-ear” hearing aid. It receives sound from
the surroundings and transmits it to a Widex wireless
hearing aid worn on the better ear, via a proprietary
wireless technology called WidexLink.
Note that you cannot use an assistive listening device
during transmission.

7
The battery
We recommend zinc-air batteries. Use a size 312 bat-
tery for the transmitter.
To obtain replacement batteries, please consult your
hearing care professional. It is important to take note
of the expiry date and the recommendations on the
battery pack regarding disposal of used batteries.
Inserting the battery
Before inserting a new battery, remember
to remove the adhesive tab. Once the tab
has been removed, the battery will start
functioning after a few seconds.
CAUTION
Do not use batteries if there is a sticky residue from the tab
or other unwanted substance, as this can cause the device to
malfunction.
Use the nail grip to gently swing the
battery drawer completely open. Do
not press the drawer beyond the open
position.

8
Place the battery in the drawer, so that the plus (+) sign
on the battery faces upward. You can use the battery
magnet provided to steer the battery into place.
If the battery drawer does not close easily, the battery
is incorrectly inserted.
Battery drawer without a nail grip
The device may be provided with a
battery drawer without a nail grip. This
type of drawer can be a good choice if
the device is worn by a child. A tool for
opening the drawer may be included
with this drawer.

WARNING
• Never leave an exhausted battery in the transmitter.
Exhausted batteries may leak, damaging the device.
• Your transmitter may stop functioning, for instance if the bat-
tery is exhausted. You should be aware of this possibility, in
particular when you are in traffic or are otherwise dependent
on warning signals.
Right/left identification
Your transmitter can be provided
with a coloured mark for right/left
identification (red mark = right and
blue mark = left).
The arrow shows the position of the
identification mark.

10
Positioning the transmitter
Insert the earpiece in the ear canal while holding the
lower part of the tube. It may help to pull the outer ear
backwards and upwards with the opposite hand.
Place the transmitter behind the ear, so that the device
and tube rest comfortably on the ear, close to your
head.
The illustrations show an open ear-tip. For further infor-
mation on ear-tip types, anchors and procedures, see
the separate ear-set user manual provided.
If the ear-set does not fit or sit properly, causing dis-
comfort, irritation, redness or the like, contact your
hearing care professional.

11
Removing the transmitter
Remove the transmitter from its position behind the
ear.
Carefully pull the earpiece out of the ear canal, while
holding the lower part of the tube. If the earpiece is
provided with an extraction cord, take hold of this and
carefully pull the ear-tip out of the ear canal.

12
Turning the transmitter on and off
Close the battery drawer to turn on
the transmitter.
To turn it off, open the battery drawer
slightly to the first position where a
click is felt.
Please remember to turn off the
transmitter when it is not in use.
Remove the battery if the device will
not be used for several days.
Transmission
With the transmitter turned on, press the program but-
ton to start transmitting sound to the hearing aid on the
better ear. Make sure the hearing aid is also turned on.
To stop transmission, press the program button again.
You will hear a sound when transmission is started, and
a message when transmission is stopped, unless this
function has been disabled.

13
NOTE:
If you have a DEX device, you need to turn off transmis-
sion by pressing the program button in order to use the
DEX.

listening programs in the hearing aid worn on the bet-
ter ear.

CARING FOR YOUR TRANSMITTER
The transmitter is a valuable object and should be
treated with care. Here are some things you can do to
prolong the life of your device:
CAUTION
• Turn off your transmitter when it is not in use. Remove the
battery if the device will not be used for several days.
• When the transmitter is not in use, keep it in its case in a dry
location out of reach of children and pets.
• Do not expose it to extreme temperatures or high humidity.
Make sure to dry it thoroughly after heavy perspiration such
as that which may occur during intense physical activity, e.g.
playing sports.
• Avoid dropping your device – perform cleaning and battery
changes while holding it above a soft surface.
• Do not wear your transmitter while in the shower or swim-
ming, or when using a hair dryer, and avoid letting the hearing
aid come into contact with sticky or greasy substances, such
as hair spray or sunscreen.

18
WARNINGS
WARNING
The transmitter and batteries can be dangerous if swallowed
or used improperly. Swallowing or improper use can result in
severe injury or even fatalities. In case of ingestion, contact a
physician immediately.
• Keep the transmitter and its parts and batteries out of reach
of children and anyone else who might swallow such items or
otherwise cause injury to themselves. Do not change batter-
ies in front of them and do not let them see where you keep
your battery supply. Discard used batteries carefully.
• Batteries are very small and can easily be mistaken for pills or
the like. Never put a battery or device in your mouth for any
reason as you may risk swallowing it.
• Clean and inspect your transmitter after use to check that it is
intact. If the ear-set breaks while in the ear canal, contact your
hearing care professional immediately. Do not try to remove
the parts yourself.
• Risk of explosion if battery is replaced by an incorrect type
or recharged. Dispose of used batteries according to the
instructions.
• The device is made of modern non-allergenic materials. None-
theless, in rare cases skin irritation may occur. If you notice
skin irritation in or around your ear or ear canal, contact your
hearing care professional.

19
WARNING
• Please note that when using the transmitter, you must allow
regular ventilation of the ear. If the ear is not adequately
ventilated, there may be a slightly increased risk of infection
or disease in the ear canal. We therefore recommend that you
remove the device and ear-set from your ear when you go to
bed, to allow the ear canal to be ventilated. If possible, you
should also remove your device and ear-set during the day if
there are any periods when you do not need them. Make sure
that you clean and inspect your transmitter and ear-set as
required. If an ear infection or disease occurs, you should seek
medical attention and contact your hearing care professional
for advice on how to disinfect the various device parts. Do
not under any circumstances use alcohol, chlorine or similar
substances for this purpose.
• Regular use of a de-humidifier is recommended to help avoid
malfunction of the device.
• Do not use the transmitter in mines or other areas with explo-
sive gases.
• Do not wear your transmitter during radiation, X-rays,
MRIs, CT or other similar medical treatments and scans. The
emissions from these procedures as well as from other types
of radiation, such as that in a microwave oven, can damage
your device and it can become very hot. Radiation from, for
example, room surveillance equipment, burglar alarms and
mobile phones is weaker and will not damage the device, but
may create audible interference.

20
WARNING
Interference with active Implants
• In order to show caution, we advise to follow the guidelines
recommended by manufacturers of defibrillators and pace-
makers regarding use of mobile phones:
• If you wear an active implantable device keep the Wireless
Hearing Aids and Hearing Aid Accessories such as wireless
remote controls or communicators at least 15 cm/6 inches
away from the implant.
• If you experience any interference, do not use the hearing aids
and contact the manufacturer of the implant. Please note that
interference can also be caused by power lines, electrostatic
discharge, airport metal detectors etc.
• If you have an active brain implant, please contact the manu-
facturer of the implant for risk evaluation.
If you have an implantable device, we advise to keep magnets*
at least 15 cm/6 inches away from the implant. (*= can be speci-
fied as Autophone magnet, hearing instrument case, magnet
in a tool, etc.)
