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.

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