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.

remove it only when you are ready

to use the battery.

XInsert the battery with the "+" symbol

facing up (refer to the picture).

CAUTION

Risk of injury!

XInsert the ear piece carefully and not too deeply

into the ear.

● It may be helpful to insert the right device with

the right hand and the left device with the left

hand.

use the other hand to gently pull your earlobe

downwards. This opens the ear canal and eases

insertion of the ear piece.

XDry your device overnight.

XAsk your Hearing Care Professional for recommended

drying products.

Ear pieces

Cleaning

Cerumen (ear wax) may accumulate on the ear pieces.
