Your CROS transmitter

CROS solutions are designed for people with profound

hearing loss in one ear which can not be aided with a hearing

aid. A CROS transmitter worn on this ear captures sound

from this side and transmits it to the hearing aid on the

other ear. This allows the wearer of the hearing aid to hear

sounds from both sides.

Two solutions are available:

zCROS 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.

zBiCROS 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 aid

processes and amplies the sounds from both sides.

The CROS transmitter works with our specic wireless

hearing aids. Your Hearing Care Professional will advise

you on the compatible models.

NOTICE

This user guide only applies to the CROS transmitter.

Your hearing aid has a separate user guide.
