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.
This booklet & your instrument
In this booklet you will find explanations on controlling your instrument, on the daily
handling of it, and on its use. Furthermore, you can read what to do if things do not live
up to your expectations. We will also give a few practical steps towards better hearing.

Switching on and off
Your hearing instrument is switched off by opening the battery
door.
Off-open
Switch your instrument on by closing the battery door.
After your instrument is switched on, the volume will always be On-close
as set by your hearing care professional. Read more on this on
page 15.
Changing batteries.
When the hearing instrument generates a warning signal it’s
advisable to change your battery as soon as possible. The sig­
nal 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.
Your instrument can have a push button to switch programs. However, if you close the
battery door your instrument will always start in program number 1. Read more on this
subject on page 16.
Open the battery door by placing your fingernail or a pencil un­
der the edge of the battery door and gently push it backwards.
When opened, remove the dead battery. The end of the clean­
ing brush is magnetic. It allows for easy battery removal/inser­
tion.
At night, leave the battery door open. It increases battery life and allows moisture in your
instrument to evaporate and increases the instrument’s life span.
The replacement battery type and size depends on your hearing instrument. Please
consult your hearing aid professional.

Remove the protective seal from the fresh battery and insert it
in the battery door, with the plus side facing up. You will recog­
nize the plus side of the battery because it is marked with a +.
• Keep batteries away from children and mentally challenged persons.
Always insert a battery in the opened door, never directly into
the instrument.
• Batteries can be harmful if swallowed. If you do, seek medical attention immedi­
ately.
Close the battery door. This should go smoothly, so never force
it as this could damage your instrument.
• Do not attempt to recharge the batteries, as they could explode.
Warnings
• Do not burn the batteries, as they could explode.
• Replace spent batteries and do not leave them in the instrument for a prolonged
period.
• Used batteries are harmful to the environment. Please dispose of them according
to local regulations or return them to your hearing care professional.

Inserting and removing the instrument
Inserting
• The insertion process varies with the shape of your ear
canal. A fairly straight ear canal allows easy insertion. How­
ever, some ear canals have sharper curves and may require
more care.
• Take the hearing instrument between thumb and index finger
and position its ‘point’ in your ear canal.
• Now slide the instrument all the way into your ear canal with
a gentle, twisting motion. Insertion can be easier if you gently
pull your auricle backward with your other hand.
• Move the instrument up and down with your index finger and
press gently to ensure it is positioned correctly. Opening and
closing your mouth can aid insertion. You will feel when the instrument is inserted cor­
rectly.
• When correctly positioned switch on your instrument by closing the battery door.
12
• You may insert the hearing instrument while in the on position. However you might
experience some feedback (whistling) during the operation.
Removing your instrument
• Using your thumb and index finger gently pull the hearing instrument (not the bat­
tery door) from your ear. CIC instruments and MC instru­
ments often have a removal cord which should be utilized to
remove your hearing instrument. Never pull the battery door.
• Removal may be easier if you open and close your mouth
while simultaneously pulling your hearing instrument back­
ward with your other hand.
• Consult your hearing care professional if you have difficulties
­removing the hearing instrument.
Take some time at home to practice how to insert and remove your instrument.
13
Recognizing left and right instruments
Your hearing instrument is custom-made to fit your ear. Therefore, right and left instru­
ments differ in shape.
Do not swap your hearing instruments. Please pay attention to this during cleaning,
storing, and inserting.
Setting the volume on STAGE (optional)
Your instrument has an optional volume control. Your hear­
ing instrument professional will have chosen an optimal
volume setting for you and explain at what level that is.
In difficult situations some people can benefit for adjusting the
volume from this setting. On the MC, ITC and ITE a volume
wheel is available and can provide you with the ability to adjust
the volume to your liking. This volume wheel is not available
on CIC hearing instruments.
Use your index finger to turn the volume wheel. Turn the wheel forwards to increase and
turn it backward to decrease the volume.
14
15
Program button (optional)
Your hearing instrument can be equipped with three different
listening programs. Each program will have the most suitable
settings for certain situations.
When you close the battery door and switch the instrument on it will start in program
1, confirmed by one single beep.
After pressing the program button, the instrument change pro­
grams. If it was in program 1 it will switch to program 2, if it
was in program 2 it will switch to program 3.
Let your hearing care professional fill out the following table:
If programs 2 or 3 are not activated, nothing will happen.
Press the program button if you want to move to a different listening program.

Telecoil program (optional)
Your ITC instrument or ITE instrument may have a built in function, the telecoil,
enabling in many cases an improved use of the telephone and better hearing in
those churches or halls where an induction loop system is installed.
In order to activate this function, the telecoil program has to be selected. In this pro­
gram you will hear no sounds from the microphone, therefore most environmental
sounds will be lost.
Using the telephone
• Switch your instrument to the telecoil program.
• Hold your telephone handset behind your ear, close to the
hearing instrument, approximately 1 inch, and slightly tilt the
telephone receiver outwards.
• Listen to the dialing tone and move the handset around to
find the position that give the best reception.
18
• If needed, and if your hearing instrument has it, turn the volume wheel up or down.
• After completing the phone call, switch your instrument back to the microphone
program.
If the phone used has poor telecoil signal, use the microphone program. Do not hold
the handset too tightly against your ear since this might cause ‘whistling’.
Hearing through an induction loop
More and more public places, churches, theatres and cinemas, have induction loop sys­
tems. In these particular rooms, they transmit, wirelessly, the sound of the presenter or
show. At home, radio or television can be connected to an induction loop. Sound quality
through an induction loop is often better because noises from the environment are not
transmitted.
• Switch your instrument to the Telecoil program (if available), using the program
button.
• Reception is not clear at all locations; it depends on the position of the induction loop.
19
• If needed, adjust the volume up or down.
• After utilizing the telecoil program, switch your instrument back to a microphone pro­
gram by pushing the program button. You will now hear through the microphone
again.
• Your hearing care professional will gladly provide you with advice regarding an induc­
tion loop system at home.
i
Maintenance and cleaning
Your hearing instrument is protected by a layer of protective, hydrophobic
nanocoat material.
2. Never immerse hearing instruments in water or other liquids,
as liquids may cause permanent damage to the hearing in­
struments.
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.
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).
6. If your instrument does get wet, or if it has been exposed to high humidity or per­
spiration, 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.
20
7. Remove your hearing instrument when applying such things as cosmetics, perfume,
21
Please follow the following instructions to prolong the durability of your hearing instru­
ments:
aftershave, hair spray, and suntan lotion. These might get into the instrument and
cause damage.
8.Earwax (cerumen) will accumulate on your hearing instru­
ment during use. If earwax enters the instrument it can
damage it. The instrument has a protection system, the wax
guard. Clean the instrument and replace the wax guard filter
regularly. Failure to do so can lead to an accumulation of ear­
wax impairing sound quality.
Cleaning is easier when accumulated earwax is dry; e.g., in the morning, before you
insert the instrument into your ear.
Cleaning the vent
Your hearing instrument may have a vent, a small canal through
the entire instrument. If so, clean it regularly.
• Insert the vent-cleaning tool – plastic line with handle – into
the vent. Push the cleaning line completely through the vent.
22
• Wipe off any collected earwax.
• Pull the line out and wipe off again.
• Repeat this until all the earwax has been removed.
Wax guard
Your hearing instrument is usually equipped with a wax guard system. This prevents
earwax entering the instrument. Replace the wax guard every two weeks or sooner,
depending on earwax accumulation. Please consult your hearing professional for infor­
mation on the wax protection selected for your custom hearing instrument.
Storing your instrument
When you are not using your instrument, keep or transport it in the case 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 hearing aid dryer
from your hearing care professional.
Cleaning the microphone opening
Your instrument will not work properly if the microphone opening is dirty. Ask the hear­
23
ing care professional to clean the opening. Never try this yourself.
i
General warnings and precautions
• 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 hearing aid dryer. Your hearing care
professional 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 profes­
sional. 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 su­
pervised at any time.
24
• 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.
• 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 hear­
ing 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.
25
Intended Use
Generic air-conduction hearing instruments are wearable sound-amplifying devices
intended to compensate for impaired hearing. The fundamental operating principle of
hearing instruments is to receive, amplify, and transfer sound to the ear drum of a hear­
ing impaired person.
Notice:
1. A hearing aid will not restore normal hearing and will not prevent or improve a hearing
impairment resulting from organic conditions.
2. Consistent use of the aid is recommended. In most cases, infrequent use does not
permit you to attain full benefit from it.
3. The use of a hearing aid is only part of hearing rehabilitation and may need to be
supplemented by auditory training and instructions in lip-reading.
Important Notice for Prospective Hearing Aid Users
Good health practice requires that a person with a hearing loss have a medical evaluation
by a licensed physician (preferably a physician who specializes in diseases of the ear)
before purchasing a hearing aid. Licensed physicians who specialize in diseases of the
26
ear are often referred to as otolaryngologists, otologists or otorhinolaryngologists. The
purpose of the medical evaluation is to assure that all medically treatable conditions that
may affect hearing are identified and treated before the hearing aid is purchased.
Following the medical evaluation, the physician will give you a written statement that
states that your hearing loss has been medically evaluated and that you may be con­
sidered a candidate for a hearing aid. The physician will refer you to an audiologist or a
hearing aid dispenser, as appropriate, for a hearing aid evaluation.
The audiologist or hearing aid dispenser will conduct a hearing aid evaluation to assess
your ability to hear with and without a hearing aid. The hearing aid evaluation will enable
the audiologist or dispenser to select and fit a hearing aid to your individual needs.
If you have reservations about your ability to adapt to amplification, you should inquire
about the availability of a trial-rental or purchase-option program. Many hearing aid dis­
pensers now offer programs that permit you to wear a hearing aid for a period of time
for a nominal fee after which you may decide if you want to purchase the hearing aid.
Federal law restricts the sale of hearing aids to those individuals who have obtained a
medical evaluation from a licensed physician. Federal law permits a fully informed adult
27
to sign a waiver statement declining the medical evaluation for religious or personal be­
liefs that preclude consultation with a physician. The exercise of such a waiver is not in
your best health interest and its use is strongly discouraged.
(ii)History of active drainage from the ear within the previous 90 days.
Children with Hearing Loss
In addition to seeing a physician for a medical evaluation, a child with a hearing loss
should be directed to an audiologist for evaluation and rehabilitation because hearing
loss may cause problems in language development and the educational and social
growth of a child. An audiologist is qualified by training and experience to assist in the
evaluation and rehabilitation of a child with hearing loss.
(v)Unilateral hearing loss of sudden or recent onset within the previous 90 days.
i
(iii)History of sudden or rapidly progressive hearing loss within the previous 90 days.
(iv)Acute or chronic dizziness.
(vi)Audiometric air-bone gap equal to or greater than 15 decibels at 500 hertz (Hz),
1,000 Hz, and 2,000 Hz.
(vii)Visible evidence of significant cerumen accumulation or a foreign body in the ear
canal.
(viii) Pain or discomfort in the ear.
Warning to Hearing Aid Dispensers
A hearing aid dispenser should advise a prospective hearing aid user to consult promptly
with a licensed physician (preferably an ear specialist) before dispensing a hearing aid if
the hearing aid dispenser determines through inquiry, actual observation, or review of
any other available information concerning the prospective user, that the prospective
user has any of the following conditions:
(i)Visible congenital or traumatic deformity of the ear.

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 professional.
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 recognize them. When you are tired from listening, re­
move your instrument and pause for a while. Talk or read aloud for a while. In that way
you will familiarize yourself with the sound of your own voice. Gradually, you will learn
to use the instrument for longer and become more comfortable with it.
30
2. Listen outside; quiet & traffic
Go outside to a quiet place, e.g., the park or woods. Listen to the environmental sounds.
Do you recognize them? Please be careful with sounds from heavy traffic at this stage
of getting used to your instrument. Sometimes it sounds very loud.
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 professional to
adjust your hearing instrument. He or she is able to inform you on other facilities, such
as an induction loop system at home for your radio or television.
31
5. Get used to conversations in a group
Following conversations in a group is often difficult because of the background noise.
Listen to the different voices. Try to recognize 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. 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.
7. Use your telephone
Often, you can hear the telephone clearly with your hearing instrument in a micro­
phone program. Hold the telephone handset approximately 1-inch from your ear and
tilt the receiver outwards a little. See whether or not the telephone sounds better
if you switch your hearing instrument to the Telecoil program. Read about this on
page 18.
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.
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 res­
taurant, sit with your back towards the wall. This avoids disturbing noises coming from
behind you. If an induction loop is present, and your instrument has a telecoil, use the
telecoil program. However, not every position will have good sound reception. Watch for
signs at the location or try a different seat.
8. Use your instrument all day
Using your hearing instrument and practicing 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. Of course, a hearing instrument cannot restore
natural hearing, but it will help you make the most of your hearing as it is today.
32
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.
33
Solving small problems
Your Interton instrument is a reliable one. In case of minor problems or malfunctions, you may be able to solve them yourself.
