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

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 inrument processes and amplies
the sounds from both sides.
The CROS transmitter works with our specic wireless
hearing inruments. Your Hearing Care Professional
will advise you on the compatible models.

This user guide only applies to the CROS
transmitter. Your hearing inrument has a
