Thank you for selecting an Interton ITE (In-the-Ear) hearing system!
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 instruments have been adjusted to your particular hearing
loss.
Your hearing healthcare professional will explain these adjustments and the special features of
your particular model.
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.

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.
Open the battery door by placing your fingernail or a pencil
under the edge of the battery door and gently push it back-
wards. When opened, remove the dead battery. The end of the
cleaning brush is magnetic. It allows for easy battery removal/
insertion.
The replacement battery type and size depends on your hearing instrument:
Instrument type Battery type
CIC HPG-P 10A zinc-air
MC HPG-P/U 10A zinc-air
ITC/ITC HPG-P/U 312 zinc-air
ITE HPG-P 13 zinc-air
Switching on and off
Your hearing instrument is switched off by opening the battery
door.
Switch your instrument on by closing the battery door.
After your instrument is switched on, the volume will always be
as set by your hearing care practitioner. Read more on this on
page 9.
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 11.

to local regulations or return them to your hearing care practitioner.
Remove the protective seal from the fresh battery and insert
it in the battery door, with the plus side facing up. You will re-
cognize 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.
Always insert a battery in the opened door, never directly into
the instrument.
Close the battery door. This should go smoothly, so never force
it as this could damage your instrument.

• Youcanaswell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 nger gently pull the hearing
instrument (not the battery door) from your ear. CIC instru-
ments and MC instruments often have a thin plastic pullout
cord. Use this. Never pull the battery door.
• Removalmaybe easier ifyou open andcloseyour mouth
while simultaneously pulling your auricle backward with your
other hand.
Take some time at home to practice how to insert and remove your instrument. Work
conveniently positioning your elbows on a table and maybe using a mirror.
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. Howe-
ver, some ear canals have sharper curves and may require
more care.
• Takethehearinginstrumentbetweenthumbandindexnger
and position its ‘point’ in your ear canal. If available the colour
dot must point upwards on CIC instruments and on MC instru-
ments.
• 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nger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 correctly.

Setting the volume on STAGE (optional)
Your instrument has an optional volume control. Your hear-
ing instrument practioner 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.
Recognising left and right instruments
Your hearing instrument is custom-made to fit your ear. Therefore, right and left instru-
ments differ in shape.
Your hearing instrument is marked with either a left or right indication:
•Aleftinstrumenthasabluewaxguardorbluedot;
•Arightinstrumenthasaredwaxguardorreddot.
This is easy to remember: Red = Right.
The colour dot must point upwards on the CIC and on MC instruments.
Do not swap your hearing instruments. Please pay attention to this during cleaning,
storing, and inserting.

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.
Let your hearing care practitioner fill out the following table:
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.
After pressing the program button, the instrument will switch
pro-gram. 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 programs 2 or 3 are not activated, nothing will happen.
Your instrument will give an audible signal after pressing the
program button. A little later, the instrument will give:

receiver outwards.
• Listentothedialing toneandmovethehandset alittleto

• 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’.
T-program (optional)
- ITC/ITC HPG and ITE HPG
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.
