Thank you for choosing our hearing instruments to accompany you through everyday life. Like anything new, it may take you a little time to become familiar with them.

This guide, along with support from your Hearing Care Professional, will help you understand the advantages and greater quality of life your hearing instruments offer.

To receive the most benefit from your hearing instruments, it is recommended that you wear them every day, all day. This will help you get adjusted to them.


It is important to read this user guide and the safety manual thoroughly and completely. Follow the safety information to avoid damage or injury.
Before using your hearing instruments for the first time, fully charge them. Follow the instructions in the charger's user guide.

Your hearing instruments

This user guide describes optional features that your hearing instruments may or may not have.

Ask your Hearing Care Professional to indicate the features that are valid for your hearing instruments.

Instrument type

Your hearing instruments are BTE (Behind-The-Ear) models. A tube delivers the sound from the hearing instrument into the ear. The instruments are not intended for children under the age of 3 years or persons with a developmental age of under 3 years.

A power cell (lithium-ion rechargeable battery) is permanently built into your hearing instrument. This enables easy charging with our inductive charger.

The wireless functionality enables advanced audiological features and synchronization between your two hearing instruments.

Your hearing instruments feature Bluetooth^® low energy* technology allowing for easy data exchange with your smartphone, and for seamless audio streaming with your iPhone**.

* The Bluetooth word mark and logos are owned by the Bluetooth SIG, Inc., and any use of such marks by the legal manufacturer of this product is under licenses. Other trademarks and trade names are those of their respective owners.

Getting to know your hearing instruments

It is recommended to familiarize yourself with your new hearing instruments. With the instruments in your hand try using the controls and note their location on the instrument. This will make it easier for you to feel and press the controls while wearing the hearing instruments.

If you have problems pressing the controls of your hearing instruments while wearing them, you can ask your Hearing Care Professional whether a remote control or a smartphone app to control your instruments is available.

Components and names

Your hearing instruments are either attached to an earhook and a custom-made ear piece or to a standard tube (ThinTube) and a standard ear piece (LifeTip).

Daily use

Charging

Place your hearing instruments in the charger.

• Follow the instructions in the charger's user guide. You can also find useful tips for charging in the charger's user guide.

Low power indication

You will hear an alert signal to indicate the power cell is running low. The signal will be repeated every 15 minutes. Depending on the usage of your hearing instruments, you have approximately 2 hours to charge your hearing instruments before they stop working.

Turning on and off

You have the following options to turn your hearing instruments on or off.

Via charger

• Turning on: Take the instruments out of the charger.
  The startup melody is played in your hearing instruments. The default volume and hearing program are set.
• Turning off: Place the hearing instruments in the charger.

Note that the charger must be connected to the power supply. For details refer to the charger's user guide.

Via push button

• Turning on: Press and hold the push button until the startup melody starts to play. Release the push button while the melody is playing.
  The default volume and hearing program are set.
• Turning off: Press and hold the push button for several seconds.

See also the tips for charging in the charger's user guide.

Switching to standby mode

Via remote control or smartphone app, you can switch your hearing instruments to standby mode. This mutes the hearing instruments. When you leave standby mode, the previously used volume and hearing program are set.

Note:

• In standby mode, the hearing instruments are not turned off completely. They draw some power.
  Therefore we recommend to use standby mode only for a short period of time.
• If you want to leave standby mode, but the remote control or app is not at hand: Turn your hearing instruments off and on again (via push button or by shortly placing them in the charger until one or more orange LEDs light up). In this case, the default volume and hearing program are set.

Inserting and removing the hearing instruments

Your hearing instruments have been fine-tuned for your right and left ear. Colored markers indicate the side:

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

Inserting a hearing instrument:

• Hold the tube close to the ear piece.
• Carefully push the ear piece into the ear canal 1.
• Twist it slightly until it sits well.
  Open and close your mouth to avoid accumulation of air in the ear canal.
• Lift the hearing instrument and slide it over the top of your ear 2.

Risk of injury!

• Insert the ear piece carefully and not too deeply into the ear.

• It may be helpful to insert the right hearing instrument with the right hand and the left hearing instrument 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 position the retention strand:

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

Removing a hearing instrument:

• Lift the hearing instrument and slide it over the top of your ear 1.
• X Hold the tube close to the ear piece and pull the ear piece out carefully 2.

Risk of injury!

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

Clean and dry your hearing instruments after usage.
Read more in section "Maintenance and care".

Adjusting the volume

Your hearing instruments automatically adjust the volume to the listening situation.

• If you prefer manual volume adjustment, press the push button.
  Refer to section "Controls" for the setting of your push button.

An optional signal can indicate the volume change. Once the maximum or minimum volume has been reached, you may hear an optional signal tone.

Changing the hearing program

Depending on the listening situation, your hearing instruments automatically adjust their sound.
Your hearing instruments may also have several hearing programs which allow you to change the sound, if needed. An optional signal tone can indicate the program change.

• To change the hearing program, press the push button briefly.
  
  Refer to section "Controls" for the setting of your controls. Refer to section "Hearing programs" for a list of your hearing programs.

The default volume is applied.

Further adjustments (optional)

You can also use the hearing instrument controls to change other features, for example, the level of the tinnitus therapy signal.

Refer to section "Controls" for the setting of your controls.

Special listening situations

On the phone

When you are on the phone, hold the telephone receiver slightly above your ear. The hearing instrument and telephone receiver have to be aligned. Turn the receiver slightly so that the ear is not completely covered.

Telephone program

You may prefer a certain volume when using the phone. Ask your Hearing Care Professional to configure a telephone program.

• Switch to the telephone program whenever you are on the phone.
  
  If a telephone program is configured for your hearing instruments, it is listed in section "Hearing programs".

Audio streaming with iPhone

Your hearing instruments are Made for iPhone hearing instruments. This means you can get phone calls and listen to music from your iPhone directly into your hearing instruments.

For more information about compatible iOS devices, pairing, audio streaming and other useful functions, contact your Hearing Care Professional.

Airplane mode

In areas where the use of Bluetooth technology is not allowed (e.g. on some airplanes), you can activate the airplane mode. This turns Bluetooth in your hearing instruments off temporarily. The hearing instruments still work without Bluetooth, however direct audio streaming will not be possible and other functions will not be available.

• To activate or deactivate the airplane mode, use the controls of your hearing instruments.
  Refer to section "Controls" for more information.

An alert tone indicates when airplane mode is activated or deactivated.

Maintenance and care

To prevent damage it is important that you take care of your hearing instruments and follow a few basic rules, which will soon become a part of your daily routine.

Hearing instruments

Cleaning

Your hearing instruments have a protective coating. However, if not cleaned regularly you may damage the hearing instruments or cause personal injury.

• Clean your hearing instruments daily with a soft, dry tissue.
• Never use running water or immerse the devices in water.
  
• Never apply pressure while cleaning.
• Ask your Hearing Care Professional for recommended cleaning products, special care sets, or more information on how to keep your hearing instruments in good condition.

Drying

Your charger dries the hearing instruments while charging. You can also use conventional products to dry your hearing instruments. Ask your Hearing Care Professional for recommended drying products and for individual instructions on when to dry your hearing instruments.

Storage

• Short-term storage (up to several days): Turn off your hearing instruments via the push button or place them 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 hearing instruments in the charger, the hearing instruments are not turned off.
  
  Note that when you turn off the hearing instruments via a remote control or smartphone app, the hearing instruments are not turned off completely. They are in standby-mode and still draw some power.
• Long-term storage (weeks, months, ...): First, fully charge your hearing instruments. Turn them off via the push button before storing them. We recommend using drying products while storing the hearing instruments.
  
  At 6 month intervals you will have to charge the hearing instruments to avoid an unrecoverable deep-discharge of the power cell. Deep-discharged power cells cannot be charged anymore and they have to be replaced. We recommend recharging more frequently than 6 month intervals.

Ear pieces and tubes

Cerumen (ear wax) may accumulate on the ear pieces. This may affect sound quality.

• For hearing instruments with a standard tube (ThinTube):
  
  Clean the ear pieces daily, clean the tubes as required.
  
  Exchange the ear pieces and tubes approximately every three to six months, or sooner if you notice cracks or other changes.
• For hearing instruments with earhook:
  
  Clean the ear pieces daily.
  
  Ask your Hearing Care Professional to clean the tubes or to exchange the ear pieces and tubes as needed.

Cleaning ear pieces

• Clean the ear piece upon removal with a soft and dry tissue.
  
  This prevents cerumen becoming dry and hardening.
  
  

• Never use running water or immerse the ear piece in water.

Cleaning tubes

Never use running water or immerse the tube in water.

You can clean standard tubes (ThinTube) using a special cleaning wire. Ask your Hearing Care Professional for suitable cleaning wires.

• Screw off the tube.
  
• Carefully insert the cleaning wire into the tube 1.
• Push the cleaning wire all the way through the tube 2.
• Wipe away any cerumen or debris that is dislodged from the tube.
• Completely remove the cleaning wire from the tube.
• Screw the tube onto the hearing instrument.

Exchanging standard ear pieces (LifeTip)

• Pull off the used ear piece and plug on the new ear piece.
  

Exchanging standard tubes

• Unscrew the used tube from the adapter.
  
• Screw on the new tube.

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.
