YOUR CROS TRANSMITTER
WELCOME
Congratulations on your new CROS transmitter.
Use your CROS transmitter and hearing aid regularly, even if it takes some
time getting used to it. Infrequent users don’t usually get the full benefit of a
CROS transmitter and hearing aid.
NOTE
Your CROS transmitter and its accessories may not look exactly as illustrated in
this booklet. We also reserve the right to make any changes we consider neces-
sary.
Your CROS transmitter at a glance
The illustration shows your CROS transmitter without the ear-set. For fur-
ther information on the ear-set, see the ear-set manual. The ear-set consists
of an earwire and an ear-tip, and it is the part of your hearing aid that you
wear inside your ear.

IMPORTANT SAFETY INFORMATION
Read these pages carefully before you begin using your transmitter.
Hearing aids, CROS transmitters and batteries can be dangerous if swal-
lowed or used improperly. Swallowing or improper use can result in se-
vere injury or even fatalities. In case of ingestion, contact a doctor imme-
diately.
Take your hearing aid and transmitter out when you are not using them.
This will help to ventilate the ear canal and prevent ear infections.
Contact your doctor or hearing care professional immediately if you sus-
pect you may have an ear infection.
Remove your transmitter before showering, swimming or using a hair
dryer.
Do not wear your transmitter when applying perfume, spray, gels, lotion
or cream.
Do not dry your transmitter in a microwave oven - this will ruin it.
Never use other people’s transmitters and never allow others to use
yours, as this could damage your hearing.
Never use your transmitter in environments where there may be explo-
sive gases, such as in mines, etc.
Keep hearing aids, their parts, accessories and batteries away from chil-
dren.
5
Never try to open or repair the transmitter yourself. Contact your hearing
care professional if you need to have it repaired.
Your transmitter contains radio communication technology. Always ob-
serve the environment in which you are using it. If any restrictions apply,
you must take precautions to comply with these.
Do not expose your transmitter to extreme temperatures or high humidi-
ty, and dry it quickly if it gets wet, or if you perspire heavily.
Your transmitter should be stored and transported within the temperature
and humidity ranges of -20°C to +55°C (-4°F to 131°F) and 10%-95% rH.
Your transmitter is designed to operate from 0°C (32°F) to 50°C (122°F).

THE TRANSMITTER
Indications for use
Hearing impaired people, who are deaf in one ear and have either normal
hearing or a hearing impairment in the other ear.
Intended use
The transmitter is intended for use as a device that picks up sound at the ear
on which it is worn and transmits it to a hearing aid on the other ear. The
transmitter is worn on the deaf ear like an ordinary “behind-the-ear” hear-
ing aid. It receives sound from the surroundings and transmits it to a wire-
less hearing aid worn on the better ear, via a proprietary wireless technolo-
gy.
NOTE
It is not possible to use an assistive listening device during transmission.
The battery
Use a type 312 zinc-air battery for your transmitter.
Always use a fresh, new battery that is precisely the kind recommended by
your hearing care professional.
NOTE
Check that the battery is completely clean and free of any residue before insert-
ing it in the transmitter. Otherwise your hearing aid may not function as expec-
ted.
7
Never attempt to recharge the batteries, as they could explode.
Never leave a flat battery in the transmitter while storing it. It could leak
and ruin your transmitter.
Dispose of used batteries as indicated on the packaging and take note of
the expiry date.
Changing the battery
To change the battery, do as follows:
Take the adhesive tab off the new battery and make
sure there is no sticky substance left on it. Let it
"breathe" for 60 seconds.
Use the nail grip to gently swing the battery door
open and remove the old battery.
Now place the new battery in the drawer as shown.
Close the drawer. If it doesn't close easily, the bat-
tery is not placed correctly.
If you are not using the transmitter for a few days,
remove the battery.
NOTE
Avoid dropping your transmitter - hold it above a soft surface while changing
the battery.
8
Tamper-resistant battery drawer
If the transmitter aid is going to be used by a child, you must ask your hear-
ing care professional to provide it with a tamper-resistant battery drawer.
To open battery drawer, use the special tool you've
received, and do as illustrated.
How to tell right from left
Your transmitter will be provided with a red mark if you use it on your right
ear. The mark will be blue if the transmitter is for your left ear
Turning the transmitter on and off
To turn the transmitter on, close the battery lid.
To turn off the transmitter, push the battery lid down-
wards.
9
NOTE
Don't forget to turn off the transmitter when it is not in use.
Putting on and removing the transmitter
1
2
1. Insert the ear-set in the ear while holding the lower
part of the tube. Pulling the outer ear upwards and back-
wards at the same time can be helpful.
2. Then place the transmitter behind the ear. The trans-
mitter should rest comfortably on the ear, close to your
head.
Your transmitter can be fitted using different types of ear-sets. See the sep-
arate ear-set manual for more information about your ear-set.
NOTE
If the transmitter doesn't feel comfortable, or if it doesn't fit properly, causing
irritation, redness or the like, contact your hearing care professional.
Transmitting sound to your hearing aid
The transmitter starts streaming sound to your hearing aid immediately af-
ter you turn it on. To stop transmission push the transmission on/off button
or turn off the transmitter.
NOTE
If you have an assistive listening device, you need to turn off transmission by
pressing the transmission on/off button in order to use the it.
10
NOTE
Turn off the transmitter if you want to access different listening programs in the
hearing aid worn on the better ear.

CLEANING
Tools
You will receive the following cleaning tools with your transmitter:
1. 2. 3. 4. 5.
1. Cloth
2. Brush
3. Long wax-removing tool
4. Short wax-removing tool
5. Battery magnet
Cleaning the transmitter
Cleaning your transmitter aid every day will make it more efficient and more
comfortable to wear. Wipe the transmitter with a soft cloth (for example the
cloth you received from your hearing care professio-
nal).
If the microphone openings are still blocked, contact
your hearing care professional.
Dry your transmitter quickly if it gets wet, or if you perspire heavily. Some
people use a special dehumidifier to help keep their transmitter and hearing
aid dry and clean. Ask your hearing care professional for more information.
12
Leave the battery compartment open to ventilate the transmitter. For infor-
mation on how to clean your ear-set, see the ear-set manual.
Do not use any kind of liquid or disinfectant to clean your transmitter.
Clean and inspect your transmitter every day after use to check that it is
not broken. If it breaks while you are wearing it, leaving small fragments
in your ear canal, contact your doctor. Never try to take out the fragments
yourself.
