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.
CROS transmitter hearing aid

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 aid processes and amplifies the
sounds from both sides.
The CROS transmitter works with our specific wireless
hearing aids. Your Hearing Care Professional will
advise you on the compatible models.
NOTICE
This user manual only applies to the CROS
transmitter. Your hearing aid has a separate user
manual.

use the other hand to gently pull your earlobe
downwards. This opens the ear canal and
eases insertion of the ear piece.

your device to standby mode. This mutes the device.
When you leave standby mode, the previously used
volume and hearing program are set.
Note:
■In standby mode, the device is not turned off
completely. It draws some power.
Therefore we recommend to use standby mode
only for a short period of time.

control or app is not at hand: Turn your device off
and on again (by shortly placing it in the charger
until the green LED lights up). In this case, the
default volume and hearing program are set.

Depending on the listening situation, your device
automatically adjust their sound.
Your device may also have several hearing programs
which allow you to change the sound, if needed. An
optional signal tone can indicate the program change.
XTo change the hearing program, refer to section
“Hearing programs” for a list of your hearing
programs.
The default volume is applied.
Bluetooth

technology.
In an airplane, the use of Bluetooth functionality may
be restricted, especially during take-off and landing.

You can also find useful tips for charging in the
charger’s user manual.
Low power indication
You will hear an alert signal in your hearing aid to
indicate that the lithium-ion rechargeable battery
of your transmitter is running low. The signal will be
repeated every 20 minutes. Depending on the usage
of your hearing aids, you have approximately 1.5 hours
to charge your hearing aids before they stop working.
Note that the power cell runtime is reduced if too many
features are used simultaneously.

16
Maintenance and care
To prevent damage it is important that you take care
of your device and follow a few basic rules, which will
soon become a part of your daily routine.
Transmitter
Cleaning
Your device has protective coating. However, if not
cleaned regularly you may damage the device or cause
personal injury.
XClean your device daily with a soft, dry tissue.
XNever use running water or immerse
the device in water.
XNever apply pressure while cleaning.
XDo not use alcoholic solvent on the charging
contact.
XTo avoid corrosion, use a soft and dry tissue to wipe
off sweat or liquid from the charging contact or
device before inserting this in the charger.
XAsk your Hearing Care Professional for
recommended cleaning products, special care sets,
or more information on how to keep your device in
good condition.

17
Drying
You can use conventional products to dry your device
or the optional MECHARGE™Dry & Clean Charger.
Ask your Hearing Care Professional for recommended
drying products and for individual instructions on
when to dry your device.
Storage
■Short-term storage (up to several days):
Turn off your device by placing it in the powered
charger.
The charger must be on. If the charger is not on
and you place your devices in the charger, the
devices are not turned off. Note that when you
turn off the CROS transmitter via a remote control
or smartphone app, the device is not turned off
completely. It is in standby-mode and still draw
some power.
■Long-term storage (weeks, months, ...):
First, fully charge your CROS transmitter. Leave
it in the MECHARGE™iRIC AX Charger with the
lid closed. Once the device is fully charged, the
charger and the CROS transmitter are turned off
automatically.
We recommend using drying products while storing
the device.
At 6 month intervals you will have to charge the
device to avoid an unrecoverable deep-discharge
of the rechargeable lithium-ion battery.

18
Deep-discharged batteries cannot be charged
anymore and they have to be replaced. We
recommend recharging more frequently than at
intervals of 6 months.
Observe the storage conditions in section
“Operating, transport and storage conditions”.
Ear pieces
Cleaning
Cerumen (ear wax) may accumulate on the ear pieces.
This may affect sound quality. Clean the ear pieces
daily.
For all types of ear pieces:
XClean the
ear piece
right after
removal with
a soft and dry
tissue.
This prevents
that cerumen
becomes dry
and hard.

19
Exchanging
Exchange standard ear pieces approximately
every three months. Replace them sooner if you
notice cracks or other changes. The procedure for
exchanging standard ear pieces depends on the type
of ear piece. In section “Components and names”, your
Hearing Care Professional has marked your type of
ear piece.
XTo remove the old Eartip or Sleeve, follow the
illustration below. Be careful not to pull the receiver
cable.

20
XTake particular care that
the new Eartip or Sleeve
covers the retention rings
of the receiver fully.
XCheck the firm fit of the
new Eartip or Sleeve.
Professional maintenance
Your Hearing Care Professional can perform a
thorough professional cleaning and maintenance.
Custom-made ear pieces and wax filters should
be exchanged as needed by your Hearing Care
Professional.
Ask your Hearing Care Professional for your individual
recommendation of maintenance intervals and for
support.
