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

SIGNAL TONES

Signal tones of the CROS transmitter ‑ like a low battery

beep - are sent to the hearing inrument.

Ask your Hearing Care Professional to congure the

signal tones.

BATTERIES

When the battery is low the sound becomes weaker

or you will hear an alert signal. The battery type will

determine how long you have to replace the battery.

BATTERY SIZE AND HANDLING TIPS

Ask your Hearing Care Professional for recommended

batteries.

Battery size: 312

■ Always use the correct battery size for your device.

■ Remove the batteries if you intend not to use the

facing up into the battery door

(refer to the picture).

Note: Please do not place the battery

directly into the housing.

compartment:

completely. It draws some power. Therefore, we

recommend to use andby mode only for a short

period of time.

■ If you want to leave andby mode, but the remote

control or app is not at hand, turn your device o

and on again (by opening and closing the battery

compartment). In this case, the default volume and

hearing program are set.
