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.
CROS transmitter hearing in󰘵rument

67
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

Batteries
When the battery is low the sound becomes weaker
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.

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.

de ese lado y lo transmite al audífono del otro oído. E󰘵o
permite al usuario del audífono escuchar los sonidos de
ambos lados.
