Welcome
Thank you for choosing one of our hearing in󰘵rument
accessories.
This guide, along with support from your Hearing Care
Professional, will help you under󰘵and the advantages
and greater quality of life this accessory o󰘯ers.
CAUTION

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

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

which will soon become a part of your daily routine.
Hearing in󰄋ruments
Cleaning
Your hearing in󰘵ruments have a protective coating.
However, if not cleaned regularly you may damage the
hearing in󰘵ruments or cause personal injury.
XClean your hearing in󰘵ruments daily with a soft, dry
tissue.
XNever use running water or immerse the
devices in water.

Storage
● Short-term 󰘵orage (up to several days): Turn o󰘯 your
hearing in󰘵ruments via the push button or place them
in the powered charger.
The charger mu󰘵 be connected to the power supply.
If the charger is not connected to power supply and
you place your hearing in󰘵ruments in the charger, the
hearing in󰘵ruments are not turned o󰘯.
Note that when you turn o󰘯 the hearing in󰘵ruments
