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.

Your Hearing Instruments
Instrument Type
Your hearing instruments are a RIC (Receiver-in-Canal) model. The receiver is placed within the ear canal and connected to the instrument via a receiver cable. 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.

Contact your Hearing Care Professional for downloading and installing the smartphone app.
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 20 minutes. Depending on the usage of your hearing instruments, you have approximately 1.5 hours to charge your hearing instruments before they stop working.
Note that the power cell runtime is reduced if too many features are used simultaneously.
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 Rocker Switch:
▶️ Turning on: Press and hold the lower part of the rocker switch until the startup melody starts to play. Release the rocker switch while the melody is playing. The default volume and hearing program are set.
▶️ Turning off: Press and hold upper or lower part of the rocker switch for several seconds. A power down melody is played.
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 rocker switch 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
▶️ For Click Sleeves, take care that the bend of the Click Sleeve is in line with the bend of the receiver cable.
Correct:
Incorrect:
▶️ Hold the receiver cable at the bend closer to the ear piece.
▶️ Carefully push the ear piece in the ear canal ❶.
▶️ 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 ❷.
⚠️ CAUTION: Risk of injury! Insert the ear piece carefully and not too deeply into the ear.
ℹ️ It may be helpful to insert the right hearing instrument with the right hand and the left hearing instrument with the left hand.
ℹ️ 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 ❶.
▶️ If your hearing instrument is equipped with a custom shell or a Click Mold, remove it by pulling the small removal cord toward the back of your head.
▶️ For all other ear pieces: Grip the receiver in the ear canal with two fingers and pull it carefully out ❷. Do not pull the receiver cable.
⚠️ CAUTION: 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 upper part of the rocker switch to increase the volume or press the lower part to decrease the volume.
Refer to section "Controls" for the setting of your rocker switch.
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 rocker switch briefly.
Refer to section "Controls" for the setting of the rocker switch. 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 Function.
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.
Bluetooth
Your hearing instrument is equipped with Bluetooth wireless technology to enable audio streaming from mobile phones or other compatible devices.
In an airplane, the use of Bluetooth functionality may be restricted, especially during take-off and landing. If this is the case, you can switch off Bluetooth wireless technology in your hearing instruments via the smartphone app.
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 rocker switch 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 rocker switch 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.
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:
▶️ Clean the ear piece right after removal with a soft and dry tissue. This prevents that cerumen becomes dry and hard.
For Click Domes or Click Sleeves:
▶️ Squeeze the tip of the ear piece.
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.
Exchanging Click Domes
▶️ To remove the old Click Dome, follow the instructions on the packaging of the Click Domes. Be careful not to pull the receiver cable.
▶️ Take particular care that the new Click Dome clicks noticeably in place.
▶️ Check the firm fit of the new Click Dome.
Exchanging Click Sleeves
▶️ Turn the Click Sleeve inside out.
▶️ Grasp the Click Sleeve and the receiver (not the receiver cable) with your fingers and pull the Click Sleeve off.
▶️ Take particular care that the new Click Sleeve clicks noticeably in place.
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.
