Becoming Accustomed to Amplification
While purchasing a hearing system is a major step, it is only one step in a process towards more
comfortable hearing. A hearing loss is usually acquired gradually over many years. Successfully
adapting to the amplification your hearing system provides takes time and consistent use. You will
enjoy more benefits from your Interton® hearing system by wearing the system regularly in order to
get comfortable with using it.

On/Off Function
Switch your hearing instrument on by closing the battery door.
Switch your instrument off by a small movement of the battery
door till you feel a click. After switching on, your hearing
instrument will always start in program 1.
Read more on this subject on page 7.
• Switch your instrument off if you are not using it.
This will increase the battery life.
• At night, switch off your instrument and open the battery door
completely. It allows moisture in your instrument to evaporate
and will increase the instrument’s life span.
During the fitting of the hearing instrument, your hearing care
practitioner will have chosen an optimal volume setting for you.
Please note the setting of that particular level.
Your volume control has numbers on it to indicate the sound level.
Changing Memory Programs
Your hearing instrument has a push button allowing you to use
up to three different listening programs, each of them suitable
for certain situations.
After pressing the program button, the instrument will switch
program. If it was in program 1 it will switch to program 2, if it
was in program 2 it will switch to program 3, if it was in program
3 it will switch back to program 1.
Note: Models ISG173-V, ISG273-V and ISG283-V have only 2
programs (Basic and Noise). Models ISG373-V and ISG383-V
have 3 programs (Basic, Noise and Telecoil).
Your instru­ment will give an audible signal after pressing the program button. A little
later, the instrument will give:

When you close the battery door and switch the instrument on it will start in program 1,
confirmed by one single beep.
Press the program button if you want to move to a different listening program.
Proper Placement in the Ear
Inserting the instrument
• With the battery door opened in the off position take the
earmould between thumb and index finger and position its
‘point’ in your ear canal. Now, slide the earmould all the way
into your ear with a gentle, twisting movement. Insertion can
be easier if you gently pull your auricle backwards with your
other hand.
• Turn the top-part of the earmould gently backwards and forwards so that it fits behind the fold of skin above your ear
• Place the hearing instrument behind your ear. Move the earmould up and down and press gently to ensure it is positioned correctly in the ear. Opening and closing your mouth can
ease insertion. You will feel when the earmould is positioned correctly.
• When correctly positioned switch on your instrument by
closing the battery door.
• You can also insert the hearing instrument while in
the on position. However you might experience some
feedback (whistling) during the operation.
• Switch off the instrument by pressing the battery door in the ‘off’ position.
• Lift the hearing instrument from behind the ear. For a moment, let it hang beside your
• Using your thumb and index finger, gently pull the earmould (not the instrument or the
tubing) loose from the ear.
• Remove the earmould completely by gently twisting it.
Recognising left and right instrument
If you have two hearing instruments, they may be tuned differently. One for your left ear,
the other for your right. Do not swap them. Please pay attention to this when cleaning,
storing and inserting the instruments.
• You might want to ask your hearing care practitioner to mark your instruments with
a coloured Left and Right indication: Left is blue and Right is red.
Using the Telephone While Wearing your Hearing System
Close proximity to a telephone can sometimes cause hearing instruments to make a squealing sound, also known as feedback.
To reduce the potential for this problem, position the phone close
to the hearing instrument, but not directly on the instrument. This
technique may require practice.
The Telecoil Feature (For models ISG373-V and ISG383-V)
Your hearing system has a built-in telecoil. When a telecoil is
activated, the hearing instrument will only detect and process
sounds coming from the telephone.
To activate the telecoil choose memory 3 with the Program button.
To use the telephone while the telecoil is activated, position the telephone near, but not
directly on the instrument. You may need to re-position to find the best reception.
Cellular Phone and Hearing Instrument Compatibility
Hearing instrument performance with cellular phones may vary based on the individual
hearing system or the cell phone being used. If your hearing system and cell phone are
not compatible you may experience a buzzing or clicking noise while using the two in
conjunction. If this is the case with your current hearing system and cell phone, consult
with your hearing healthcare professional to see if there are options to improve the sound
Measures you can take to prevent this situation:
• When purchasing a hearing system, be sure to test it with your existing phone to
determine compatibility.
• When shopping for a new cell phone, be sure to test it with your hearing system
before purchasing.
For additional guidance, please consult your cell phone provider.
Using Assistive Listening (Tele-Loop) Systems
Many gathering places are equipped with assistive listening (tele-loop) systems, for
example, in schools, theaters and houses of worship. To take advantage of a tele-loop
system, select the telecoil program (program 3). When the telecoil program has been
selected, you will be able to hear a clean sound signal via the tele-loop system. If the
instrument goes dead in the telecoil program, this may be because the loop system
is not operating.
Changing batteries
When the hearing instrument generates a warning signal it’s advisable to change your
battery as soon as possible. The signal will continue as long as the battery is not changed
or unless it does not run out of power, and therefore it is
advisable to keep an extra battery at hand.
If a school, theater or house of worship does not have a tele-loop system, try and sit
as close as possible to the front and use one of the microphone programs.
Open the battery door by placing your fingernail or a pencil on
the edge of the battery door and gently pull it down. When
opened, remove the dead battery by sliding it out as shown
in the drawing.
Removing/Inserting the Battery
The replacement battery has to be of type: 13 zinc-air. Remove the protective seal from
the fresh battery and insert it in the battery door, with the plus side facing up. You will
recognize the plus side of the battery because marked with a +. Check whether the +
symbols on the battery and on the battery door are on the same side. Close the battery
door. This should go smoothly, so never force it as this could damage your instrument.
• Keep batteries away from children and mentally challenged persons.
• Batteries can be harmful if swallowed. If you do, seek medical attention immediately.
• Do not attempt to recharge the batteries, as they could explode.
• Do not burn the batteries, as they could explode.
• Replace spent batteries and do not leave them in the instrument for a prolonged
• Used batteries are harmful to the environment. Please dispose of them according to
local regulations or return them to your hearing care practitioner.
Maintenance and cleaning
Earwax (cerumen) can accumulate in and on the earmould during use. Therefore, clean
your earmould regularly. Failure to do so can lead to an accumulation of earwax, impair­
ing sound quality.
Keep your hearing instrument clean and dry. Wipe the case with a soft cloth or tissue
after use to remove grease or moisture. You should avoid exposing your instrument
directly to moisture such as rain or water from the shower. 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 them in a sealed container together with a drying agent (dessicator) overnight.
Consult your hearing care professional as to which drying agent to use.
Storing your instrument
When you are not using your instrument, keep or transport it in the box supplied. Leave
the battery door open. Keep your instrument in a dry place, not in a bathroom or other
humid place. Alternatively, you could store the instrument in a dessicator available from
your hearing care practitioner.
Cleaning the earmould
• First, remove the tubing and earmould from the hearing instrument. Keep left and right instrument separated.
• Remove earwax with the cleaning brush and a soft cloth. If
need­ed, use a mild solution of soft soap and water or a special
clean­ing solution. Ask your hearing care practitioner for detailed
• Rinse the earmould with water.
Note: Do not use water or other liquid on the hearing instrument
• Dry the earmould with a cloth.
• Blow possible water drops from tubing and earmould. A special
device is available for this from your hearing care practitioner.
• Ensure that the earmould and tubing are completely dry before attaching them to the hear­
ing instrument. Take care with left and right instruments, check the figures on page 8.
Replacing the tube
Ask your hearing care practitioner to replace the tubing from the instrument to the earmould
if it turns stiff or changes colour.
General warnings
• Do not leave your hearing instrument in the sun, near an open fire or in a hot, parked car.
• Do not wear your instrument while showering, swimming, in heavy rain or in a moist
atmosphere such as steam bath or sauna.
• Should your instrument become moist, put it in a dessicator. Your hearing care practitioner
will be happy to counsel on this.
• Remove your instrument when applying cosmetics, e.g. perfume, aftershave, hair spray,
suntan lotion.
• Hearing instruments should be used only as prescribed by your hearing care practitioner.
Incorrect use may result in sudden and permanent hearing loss.
• Do not allow others to use your hearing instrument. It may cause permanent damage.
• Hearing instrument usage by children or mentally challenged persons should be supervised at any time.
• Do not take your instrument into rooms where you receive treatment with X-rays or MRI.
• Wearing a hearing instrument might cause an increased pro­duction of earwax. In rare
cases, the anti-allergenic materials may cause skin irritation. If so, or if in doubt, consult
your physician or ENT consultant.

Eight steps towards better hearing
You need to get used to your new hearing instrument. Sounds seem new and different.
That is because you grew accustomed to your diminished hearing. Therefore, familiar sounds
seem strange or unnatural at first. Every first-time user of a hearing instrument responds
differently to this. Some can wear the new instrument a whole day right from the start while
others find it hard to get used to.
After a while, you will notice you appreciate hearing with a hearing instrument and that you
will find it quite normal. Below, eight steps are described that will guide you through the initial
period. If you are not satisfied or keep experiencing problems, please consult your hearing
care practitioner.
1. Get used to familiar sounds at home
Try to get used to the new sounds from a familiar environment. Listen to the different (background) sounds and try to recognise them. When you are tired from listening, remove your
instrument and pause for a while. Talk or read aloud for a while. In that way you will familiarise
yourself with the sound of your own voice. Gradually, you will learn to use the instrument for
longer and become more comfortable with it.
2. Listen outside - quiet & traffic
Go outside, to a quiet place, e.g., the park or woods. Listen to the environmental sounds.
Do you recognise them?Please, be careful with sounds from heavy traffic at this stage of
getting used to your instrument. Sometimes they sound very loud; try not to get frightened.
3. Have a conversation with a single person
Use your instrument in conversation with one person; a family member or a friend. Move to
a quiet spot. Explain that you are now wearing a hearing instrument; ask the other person to
talk normally. Look at your conversation partner. If your instrument is tuned to your requirements you will be able to communicate better than before.
4. Listen to radio or television
Listen to the radio or television. Start with the news, then turn to another program. Ask a
‘normal hearing’ person to set the volume of your radio or television to a comfortable level. If
necessary, adjust the volume on your hearing instrument.
If you cannot understand the radio or television, ask your hearing care practitioner to
adjust your hearing instrument. He or she is able to inform you on other facilities such as an
induction loop at home for radio or television.
5. Get used to conversation in a group
Following conversations in a group is often difficult because of the background noise. Listen
to the different voices. Try to recognise them by timbre or rhythm and link each voice to a
person.Focus your attention on the person you want to understand. Practice this regularly. If
you did not understand something that was said, please ask for it to be repeated.
Ensure that you can see the face of your conversation partner(s) clearly and that there is sufficient light. This will help you to lip-read. Avoid ‘looking into the light,’ position yourself with
your back towards the window so that you can see the other person(s) better.
Ask others to talk slowly and clearly. Talking louder does not help.
6. Visit public buildings
Visit public buildings. Try to sit near the speaker; try to be seated in the front rows in a show.
Avoid a seat behind a pillar or in an alcove, you will be in a ‘sound shadow.’ In a restaurant, sit
with your back towards the wall. This avoids disturbing noises coming from behind you.
Some public buildings have an inductive loop system. In these buildings use your telecoil
program, if activated. However, not every position in the building will have good sound
reception. Watch for signs at the location or try a different seat.
7. Use your telephone
Often, you can hear the telephone clearly with your hearing instrument in the microphone
program. Hold the telephone handset 1 inch (2-3cm) from your ear and tilt the receiver
outwards a little.
Your hearing instrument meets strict international regulations. Therefore, it should be
possible to use a GSM telephone in most cases. However, in some circumstances,
disturbance might be audible through your hearing instrument.
8. Use your instrument all day
Using your hearing instrument and practising with it is the best way to learn to hear again.
Even if you can hear without an instrument in some cases. Try to wear your instrument all
day. In that way you will benefit the most.
Of course, a hearing instrument cannot restore natural hearing, but it will help you make the
most of your hearing as it is today.
Go beyond these eight steps and discover the world of sound around you. Do the things
you enjoy and listen to the sounds from your environment.
Hearing instrument identification
Your hearing care professional place a check mark in the below table to identify the
model you have received.
Model receivedHearing care professional
Serial number Right:
Serial number Left:
If your Interton® hearing instrument malfunctions, it must be repaired by a qualified
technician. Do not attempt to open the case of the hearing instrument since this would
invalidate the warranty. If your Interton® hearing instrument requires service, please
contact your hearing care professional for assistance.
General Precautions
• Consult a physician if you find 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 or CT scanners, may damage the hearing
instrument. Therefore, do not wear the hearing instrument during these or other corresponding scanning procedures. Other types of radiation (burglary alarms, room surveillance systems, radio equipment, mobile telephones, etc) contain less energy and
will not damage the hearing instrument. They could however momentarily affect the
sound quality or create strange sounds from the hearing instruments.
• Warning: Do not wear the hearing instrument in mines or other explosive areas,
unless those areas are certified for hearing instrument use.
Warning to the hearing care practitioner
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.
