Thank You
Becoming Accustomed to Amplification
Thank you for selecting an Interton hearing system. We are proud of our hearing products and are confident you have chosen one of the best products available.
While purchasing a hearing system is a major step, it is only one step in a process toward more comfortable
hearing. Successfully adapting to the amplification your hearing system provides takes time and consistent
You will enjoy more benefits from your Interton hearing system by taking the following actions:
• Wear the system regularly in order to get comfortable with using it.
Please familiarize yourself with the information in this guide. It contains important instructions for proper
use and care, technical performance information, and other general information about your hearing system.
Your hearing system has been adjusted to your particular hearing loss. Your hearing health care professional
will explain these adjustments and the special features of your particular model.
All the key features and functions of your hearing system are explained in
video tutorials. To watch them simply scan QR codes and watch the videos
on your smartphone. If you do not have scanning application installed yet you
can go to on your mobile browser to download free application. (ScanLife® is one of the free applications you can use to play QR codes,
you can also use any other QR scanner to play the videos).
• It takes time to get used to a hearing aid. It may help to begin by wearing your hearing aid for short
periods – even as little as 15 minutes – and then gradually building up your wearing time. In a way, it’s
no different than adjusting to contact lenses. Speak to you hearing care professional, who can design
a schedule tailored just for you.
• As you get more comfortable with the system, increase the wearing time and wear your hearing system
in multiple types of listening environments.
It may take as long as several months for your brain to get used to all the “new” sounds around you. Following these suggestions will give your brain time to learn how to interpret amplification and increase the
benefits you get from using an Interton hearing system.

On&Off function
1. When the battery door is closed,
the hearing instrument turns on, and the
default program will be activ­ated.
2. To turn off the hearing instrument, open the battery
door. Many individuals can use their fingernail to pull it
Whenever the hearing instruments are not in use, remember to turn them off
to avoid unnecessary battery consumption.
Delayed activation
Hearing instruments can be turned on once you have placed them on your ears. If you prefer to turn them
on just prior to placing them on your ear, your hearing care professional can activate a function called
Delayed on-activation. This function will delay the time in which the hearing instruments turn on by several
seconds after the battery compartment is closed. With Delayed on-activation, a beep will be heard for each
second of the delay period.
Inserting/Replacing the battery
1. Open the battery door completely by using your
2. Remove the used battery if present. Insert the new
battery with the positive side in the correct position.
3. Gently close the battery door.
Always use new Zinc-Air batteries that have a minimum remaining shelf-life
of 1 year.
Scan a QR code with your
smart phone and watch a
instruction video.
1. Remove the batteries to prevent leakage when the hearing instruments are not in use for an extended
period of time.
2. Do not attempt to recharge batteries (Zinc Air) which are not specifically designated as rechargeable
because they may leak or explode.
3. Do not place batteries in your mouth. Consult a physician immediately if a battery has been swallowed,
as they can be harmful to your health.
4. Keep batteries away from pets, children and individuals who are mentally challenged.
5. Do not attempt to dispose of batteries by burning them. Used batteries are harmful to the environment.
Please dispose of them according to local regulations or return them to your hearing care practitioner.
Low battery indicator
Your hearing care professional can set your hearing instrument to give an acoustical indication when the
battery is reaching its end of life. The hearing instrument will reduce amplification and emit a melody if battery power gets too low. This signal will recur every five minutes until the hearing instrument automatically
switches off. It is recommended that you keep spare batteries on hand.
Low battery indicator (instruments paired with accessories only)
Active usage of the Interton wireless accessories (Remote Control, Phone Clip and TV Streamer) requires
more battery power from the hearing instruments than when these are working on their own. When the
battery in the hearing instrument has depleted to a level at which use of the Interton TV Streamer TV and
Phone Clip cannot be supported, the hearing instrument will play two sets of descending tones. After
this, your hearing instrument and Interton Remote Control will continue to work as usual, but you will not
be able to use your Interton TV Streamer and Phone Clip. At some point the battery level will not support
the remote control either and you will once again hear the descending tones. The hearing instruments will
continue to work as usual. Once a new battery is inserted, full operation of the accessories will resume.

Telephone use
Listen to radio or TV
Finding the optimal position for holding a telephone may require practice for some
individuals, and one or more of the following suggestions may be helpful.
1. Hold the telephone as you would normally.
2. Hold the telephone towards the top of the ear (closer to where the microphones
3. If whistling occurs, it may take a few seconds of holding the telephone in the
same position before the hearing instrument eliminates the feedback.
4. Any whistling may also be decreased by holding the telephone slightly away from
the ear.
5. Depending on your individual needs, your hearing care professional may activate
a programme specifically for telephone use.
When listening to the TV or the radio, start out by listening to news commentators since they usually speak
clearly, then try other programmes. If you find it difficult to listen to TV or radio, your hearing care professional will be able to give you advice on available accessories to enhance your listening capabilities for TV
and radio.
Cellular phones
Your hearing instrument is designed to comply with the most stringent Standards of International Electromagnetic Compatibility. However, not all cell phones are hearing instrument compatible. The varying degree of disturbance can be due to the nature of your particular cellular phone or of your wireless telephone
service provider.
If you find it difficult to obtain a good result while using your cellular phone, your hearing care professional
will be able to give you advice on available accessories to enhance listening capabilities.
3. Place the magnets just below the telephone receiver. Make sure not to cover the microphone openings.
If necessary, move the magnet to another position to improve ease of use and comfort while speaking.
4. If you are not satisfied with the strength of AutoPhone, you can reposition the AutoPhone magnet or add
additional AutoPhone magnets.
AutoPhone (optional)
The AutoPhone function, allows your hearing instrument to automatically
switch to your tele­phone programme when a telephone receiver with an AutoPhone magnet is raised to the ear. When the telephone receiver is removed
from the ear, the hearing instrument automatically returns to the previous listening programme.
Only use a recommended cleaning agent to clean the telephone prior to placing the magnet on the
Placement of AutoPhone magnets
Place AutoPhone magnet on your telephone receiver to allow operation of the
AutoPhone function. In order to place AutoPhone magnet properly:
1. Clean the telephone receiver thoroughly.
2. Hold the telephone vertically, in a position similar to when making a telephone call.
Scan a QR code with your
smart phone and watch a
instruction video.
AutoPhone usage
Telephones can be used in a normal manner. A short melody will indicate that the AutoPhone feature has
automatically switched the hearing instrument to your telephone programme. Initially, you may need to
move the telephone receiver slightly to find the best position for reliable AutoPhone activation and good
hearing on the telephone. When you remove the telephone receiver AutoPhone will stay activated for a
few seconds to avoid accidental switching off. After that hearing instrument will switch to previously used
environmental programme.
AutoPhone warnings
1. Keep magnets out of reach of pets, children and mentally challenged persons. If a magnet is swallowed,
please seek advice from a medical practitioner.
2. The AutoPhone magnet may affect some medical devices or electronic systems. The
manufacturer of any magnetically sensitive devices (e.g. pacemakers) should advise
you regarding appropriate safety precautions when using your hearing instrument
and magnet in close proximity to the medical device or electronic system in question.
AutoPhone precautions
1. High distortion during dialing or phoning may mean that the magnet is not in the optimal position relative
to the telephone receiver. To avoid the issue, please move the magnet to another place on the telephone
2. Only use magnets supplied by Interton/GN Hearing.
if the manufacturer cannot issue a statement, we recommend keeping the magnet or a telephone
equipped with the magnet 30 cm (12”) away from magnetically sensitive devices (e.g. pacemakers).
Telecoil (optional)
Direct Audio Input (optional)
If equipped, a telecoil can be activated by your hearing care professional and accessed through one of
the additional programmes. A telecoil picks up a telephone’s magnetic signal and converts it to sound. An
optional telephone programme may help to improve speech understanding on the telephone. When using
a telecoil programme, the receiver of the telephone may need to be held closer to the hearing instrument.
The handset of the telephone may need to be moved to slightly different positions in order to find the best
Use of Direct Audio Input (DAI), which enables a direct connection of the hearing instruments to items such
as television, radio, and remote microphones, may increase speech understanding for some individuals.
The sound source is connected to the hearing instruments by a cable or a wireless FM system to the audio
boot. This accessory connects to the bottom of the hearing instruments, and once properly clicked into
place, the hearing instruments switch to DAI automatically.
Tele-loop systems (optional)
Many places, such as theatres, houses of worship, and schools are equipped with tele-loop systems.
When using a telecoil programme with tele-loop systems, sound is picked up directly and may improve
speech understanding. If there is no sound from the hearing instruments in a tele-loop system and with a
telecoil programme activated, the tele-loop system may not be turned on or is not operating correctly. If
a facility is not equipped with a tele-loop system, sitting as close as possible to the front may be helpful.
Connecting/Disconnecting audio boots
Connecting audio boots
1. Align the tip of the audio boot with the groove just above the battery compartment

Care and maintenance
Proper handling
Your hearing instrument is protected by a layer of protective, hydrophobic nanocoat material.
Please follow the following instructions to prolong the durability of your hearing instruments:
1. Keep your hearing instrument clean and dry. Wipe the case with a soft cloth or tissue after use to remove
grease or moisture. Do not use water or solvents, as these can damage the hearing instrument(s).
2. Never immerse hearing instruments in water or other liquids, as liquids may cause permanent damage
to the hearing instruments.
3. Avoid rough handling of hearing instruments or dropping them on hard surfaces or floors.
4. Do not leave hearing instruments in or near direct heat or sunlight, such as in a hot, parked car, as
excessive heat can cause damage or deform the casing.
5. Do not wear your instrument while showering, swimming, in heavy rain or in a moist atmosphere such
as a steam bath or sauna.
6. If your instrument does get wet, or if it has been exposed to high humidity or perspiration, it should be
left to dry out overnight with the battery out and the battery compartment open. It is also a good idea to
put the instrument and battery in a sealed container together with a drying agent (desiccator) overnight.
Do not use the instrument until it is completely dry. Consult your hearing care professional as to which
drying agent to use.
7. Remove your hearing instrument when applying such things as cosmetics, perfume, aftershave, hair
spray, and suntan lotion. These might get into the instrument and cause damage.
Scan a QR code with your
smart phone and watch a
instruction video.
Cleaning earmoulds
1. Remove the earmould and attached tubing from the
hearing instruments prior to cleaning.
2. Clean the earmould using a mild soap, and rinse with
lukewarm water.
3. After cleaning, dry earmoulds thoroughly and remove
any residual water and debris from the tubing utilising
an air bulb and wire loop.
Cleaning thin tubes and domes
1. Remove thin tubes from hearing instruments before cleaning by unscrewing
them counter clockwise.
2. Wipe down thin tubes and domes with a damp cloth.
3. In order to clear the thin tube of moisture and debris, push the black cleaning
rod through the thin tube, beginning at the end opposite the dome.
Thin tube and dome systems should be changed every three months or
sooner, should the components become stiff or brittle.
Earmould tubing may become stiff, brittle, or discoloured over time. Contact your hearing care professional regarding tube changes.
How to apply domes
It is recommended that your hearing care professional change domes, as incorrect dome re­place­ment
could result in the dome falling out in the ear.
Mini domes
1. Push the new dome over the flanges on the thin tube.
2. Make sure that the new dome is properly and securely mounted.
Standard domes
Standard domes are mounted in a similar manner to mini domes, but a few extra steps are required. Tulip
domes consist of two “petals”. It is important to note that the largest petal is the outermost petal.
To ensure this:
1. Push the largest petal away from the thin tube using a finger. This bends the petal forward.
2. Then push the largest petal back, and it will be placed on top of the smaller petal.
Only applicable to wireless devices
General precaution (wireless hearing instrument): When the wireless function is activated, the device uses
a low-powered digitally coded transmissions in order to communicate with other wireless devices. Although unlikely, nearby electronic devices may be affected. In that case, move the hearing instrument
away from the affected electronic device.When using wireless functionality and the devices are affected
by electromagnetic interference, move away from the source of interference.
General warnings (hearing instrument): Be careful when boarding flights, to remember to deactivate the
wireless functionality.Turn off your wireless functionality by using the flight mode in areas where radio frequency emission is prohibited.

General warnings
1. Consult a hearing care professional if you discover a foreign object in your ear canal, if you experience
skin irritation, or if excessive ear wax accumulates with the use of the hearing instrument.
Different types of radiation, e.g. from NMR, MRI or CT scanners, may damage the instrument. Therefore, do not wear the instrument during these or other corresponding scanning procedures. Other
types of radiation (burglar alarms, room surveillance systems, radio equipment, mobile telephones
etc.) will not damage the instrument. They could, however, momentarily affect the sound quality or
create strange sounds from the instruments.
Do not wear hearing instruments in mines, oil fields, or other explosive areas unless those areas are
certified for hearing instrument use.
Do not allow others to use your hearing instruments. This may cause damage to the hearing instruments or to the hearing of the other individual.
Instrument usage by children or mentally challenged persons should be supervised at all times to
ensure their safety.The hearing instrument contains small parts that could be swallowed by children.
Please be mindful not to leave children unsupervised with this hearing instrument.
Hearing instruments should be used only as prescribed by your hearing care professional. Incorrect
use may result in sudden and permanent hearing loss.
Special care should be exercised in selecting and fitting a hearing instrument(s) whose maximum
sound pressure level exceeds 132 dB SPL (with an IEC 60711:1981 occluded ear simulator), because
there may be a risk of impairing the remaining hearing of the hearing instrument user.
External devices connected to the electrical input must be safe according to the requirements of IEC
60601-1-1, IEC 60065, or IEC 60950-1, as appropriate.
