Welcome

This guide, along with support from your Hearing Care Professional, will help you understand the advantages and greater quality of life this accessory offers.

It is important to read this user guide thoroughly and completely. Follow the safety information to avoid damage or injury
It is also important to read and follow the user guide and safety manual for the hearing instrument you use with this accessory.

Your CROS transmitter

CROS solutions are designed for people with profound hearing loss in one ear which can not be aided with a hearing instrument. A CROS transmitter worn on this ear captures sound from this side and transmits it to the hearing instrument on the other ear. This allows the wearer of the hearing instrument 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:
  CROS 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 instrument processes and amplifies the sounds from both sides.

The CROS transmitter works with our specific wireless hearing instruments. Your Hearing Care Professional will advise you on the compatible models.

NOTICE
This user guide only applies to the CROS transmitter. Your hearing instrument has a separate user guide.

Inserting and removing the transmitter

Colored markers indicate the side:

• red marker = right ear
• blue marker = left ear

Inserting the device:

• For Sleeves, take care that the bend of the Sleeve is in line with the bend of the receiver cable. See the following illustrations.
  
• Hold the receiver cable at the bend closer to the ear piece.
• Carefully push the ear piece in the ear canal .
  
• Twist it slightly until it sits well.
  Open and close your mouth to avoid accumulation of air in the ear canal.
• Lift the device and slide it over the top of your ear .

Risk of injury!

• Always wear the receiver cable with an ear piece.
• Make sure that the ear piece is completely attached.

Risk of injury!

• 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.
• If you have problems inserting the ear piece, use the other hand to gently pull your earlobe downwards. This opens the ear canal and eases insertion of the ear piece.

The optional retention strand helps to securely retain the ear piece in your ear. To attach the optional retention strand:

• Align the end of the retention strand with the flat end of the receiver.
  
• Then press the retention strand towards the receiver until it clicks into place.
  

To position the retention strand:

• Bend the retention strand and position carefully into the bottom of the bowl of your ear (refer to the picture).
  

Removing a device:

• If the device is equipped with a custom shell or a mold, remove it by pulling the small removal cord toward the back of the head.
• For all other ear pieces: Grip the receiver in the ear canal with two fingers and pull it carefully out .
  Do not pull the receiver cable.

Risk of injury!

• In very rare cases the ear piece could remain in your ear when removing the device. If this happens, have the ear piece removed by a medical professional.

Clean and dry the device after usage. Read more in section "Maintenance and care".

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.

• Clean your device daily with a soft, dry tissue.
• Never use running water or immerse the device in water.
  
• Never apply pressure while cleaning.
• Do not use alcoholic solvent on the charging contact.
• 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.
• Ask your Hearing Care Professional for recommended cleaning products, special care sets, or more information on how to keep your device in good condition.

Drying

You can use conventional products to dry your device. 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 via the rocker switch or place it in the powered charger.
  The charger must be connected to the power supply. If the charger is not connected to power supply and you place your device in the charger, the device is not turned off.
  Note that when you turn off the device via a remote control or smartphone app, the device is not turned off completely. Is is in standby-mode and still draws some power.
• Long-term storage (weeks, months, ...): First, fully charge your device. Turn it off via the rocker switch before storing it. 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. Deep-discharged batteries cannot be charged anymore and they have to be replaced. We recommend recharging more frequently than 6 month intervals.
  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 pieces daily.

For all types of ear pieces:

• Clean the ear piece right after removal with a soft and dry tissue.
  This prevents that cerumen becomes dry and hard.
  

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.

• To remove the old Eartip or Sleeve, follow the illustration below. Be careful not to pull the receiver cable.
  
• Take particular care that the new Eartip or Sleeve covers the retention rings of the receiver fully.
  
• 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.
