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.

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

user guide.
