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:
zzCROS 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.
zzBiCROS 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 separate user guide.
