Your CROS transmitter
CROS solutions are designed for people with profound
hearing loss in one ear which can not be aided with
a hearing in󰘵rument. A CROS transmitter worn on
this ear captures sound from this side and transmits it
to the hearing in󰘵rument on the other ear. This allows
the wearer of the hearing in󰘵rument to hear sounds
from both sides.

Two solutions are available:
● CROS solution:
For people with normal hearing in one ear and
profound hearing loss in the other. Sounds from
the side with hearing loss are captured and
transmitted wirelessly to the good‑hearing side.
● BiCROS solution:
For people with profound hearing loss in one ear
and less severe hearing loss in the other. Sounds
from the more severe hearing loss side are captured
and transmitted wirelessly to the better‑hearing side.
The hearing in󰘵rument processes and ampli󰘰es
the sounds from both sides.
The CROS transmitter works with our speci󰘰c wireless
hearing in󰘵ruments. Your Hearing Care Professional
will advise you on the compatible models.
NOTICE
This user guide only applies to the CROS
transmitter. Your hearing in󰘵rument has a
separate user guide.

or you will hear an alert signal. The battery type will
determine how long you have to replace the battery.
Battery size and handling tips
Ask your Hearing Care Professional for recommended
batteries.
Battery size: 312
● The "battery low" signal of the CROS transmitter and
the "battery low" signal of the hearing in󰘵rument have
di󰘯erent melodies.
● Always use the correct battery size for your device.
● Remove the batteries if you intend not to use
the device for several days.
● Always carry spare batteries.
● Remove empty batteries immediately and follow
your local recycling rules for battery disposal.

Replacing batteries
Removing the battery:
XOpen the battery compartment.
XUse the magnet 󰘵ick to pull out
the battery. The magnet 󰘵ick is
available as an accessory.
Inserting the battery:
XIf the battery has a protective 󰘰lm,
remove it only when you are ready
to use the battery.
XInsert the battery with the "+" symbol
facing up (refer to the picture).
XCarefully close the battery compartment. If you feel
resi󰘵ance, the battery is not inserted correctly.
Do not attempt to close the battery compartment by
force. It can be damaged.

CAUTION
Risk of injury!
XInsert the ear piece carefully and not too deeply
into the ear.
● It may be helpful to insert the right device with
the right hand and the left device with the left
hand.
● If you have problems inserting the ear piece,
use the other hand to gently pull your earlobe
downwards. This opens the ear canal and eases
insertion of the ear piece.
The optional retention 󰘵rand helps to securely retain the
ear piece in your ear. To position the retention 󰘵rand:
XBend the retention 󰘵rand and
position it carefully into the
bottom of the bowl of your ear
(refer to the picture).

૜
૝
XFor all other ear pieces: Grip the receiver in the
ear canal with two 󰘰ngers and pull it carefully out ➋.
Do not pull the receiver cable.
CAUTION
Risk of injury!
XIn very rare cases the ear piece could remain
in your ear when removing the device. If this
happens, have the ear piece removed by a
medical professional.
Clean and dry your device after usage.
Read more in section "Maintenance and care".

Maintenance and care
To prevent damage it is important that you take care of
your device and follow a few basic rules, which will soon
become a part of your daily routine.
Device
Drying and 󰄋orage
XDry your device overnight.
XAsk your Hearing Care Professional for recommended
drying products.
XFor longer periods of non-use, 󰘵ore your device with
open battery compartment and battery removed in a
drying sy󰘵em to avoid the adverse e󰘯ects of moi󰘵ure.
Cleaning
Your device has a protective coating. However, if not
cleaned regularly you may damage the device or
cause personal injury.
XClean your device daily with a soft, dry tissue.
XNever use running water or immerse
the device in water.
XNever apply pressure while cleaning.
XAsk your Hearing Care Professional for recommended
cleaning products, special care sets, or more

Signia CROS Pure EN.indd 17 01.02.2016 12:38:00

18
Ear pieces
Cleaning
Cerumen (ear wax) may accumulate on the ear pieces.
Clean the ear pieces daily.
For all types of ear pieces:
XClean the ear piece
right after removal with
a soft and dry tissue.
This prevents that
cerumen becomes
dry and hard.
For Click Domes:
XSqueeze the tip of the dome.
Signia CROS Pure EN.indd 18 01.02.2016 12:38:00

19
Exchanging
Exchange 󰘵andard ear pieces approximately every
three months. Replace them sooner if you notice
cracks or other changes. The procedure for exchanging
󰘵andard ear pieces depends on the type of ear piece.
In section "Components and names", your Hearing Care
Professional has marked your type of ear piece.
Exchanging Click Domes
If you have problems removing the old Click Dome,
use the removal tool or follow the in󰘵ructions on
the packaging of the Click Domes:
The removal tool is available as an accessory.
