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.

11

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

device for several days.

■ Always carry spare batteries.

■ Remove empty batteries immediately and follow your

local recycling rules for battery disposal.

12

REPLACING BATTERIES

Removing the battery:

XOpen the battery compartment.

XUse the magnet ick to pull out the

battery. The magnet ick is available

as an accessory.

Inserting the battery:

XIf the battery has a protective lm, remove it

only when you are ready to use the battery.

XInsert the battery with the "+" symbol

facing up (refer to the picture).

Carefully close the battery compartment. If you feel

resiance, the battery is not inserted correctly.

XDo not attempt to close the battery compartment by

force. It can be damaged.

13

DAILY USE

TURNING ON AND OFF

You have the following options to turn your device on or

o.

Via battery compartment:

SWITCHING TO STANDBY MODE

Via remote control or smartphone app, you can switch

your device to andby mode. This mutes the device.

When you leave andby mode, the previously used

volume and hearing program are set.

Note:

■ In andby mode, the device is not turned o

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 (via rocker switch or by opening and closing

the battery compartment). In this case, the default

volume and hearing program are set.

15

INSERTING AND REMOVING THE TRANSMITTER

Colored markers indicate the side:

■ red marker = right ear

■ blue marker = left ear

Inserting:

XFor Click Sleeves, take care that the

bend of the Click Sleeve is in line with

the bend of the receiver cable.

Correct:

Incorrect:

16

XHold the receiver cable at the bend closer to the

ear piece.

XCarefully push the ear piece in

the ear canal ➊.

XTwi it slightly until it sits well.

use the other hand to gently pull your earlobe

downwards. This opens the ear canal and eases

insertion of the ear piece.
