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.
Remove ‘dead’ battery
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.
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 down. 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.

Inserting and removing the instrument
(standard earmould)
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 canal.
• Placethehearinginstrument
behind your ear. Move the ear-
mould 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aswellinsertthehearinginstrumentwhileinthe
on position. However you might experience some feedback
(whistling) during the operation. This feedback can be prevented
by enabling ”Delayed Activation”. Ask your hearing care
practitioner about this feature.
Removing your instrument
• Switchofftheinstrumentbypressingthebatterydoortothe
‘off ’ position.
• Liftthehearinginstrumentfrombehindtheear.Foramoment,
let it hang beside your ear.

(not the instrument or the tubing) loose from the ear.
• Removetheearmouldcompletelybygentlytwistingit.
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
(ThinTube)
Inserting the instrument
• Hangtheinstrumentoverthetop
of the ear.
• Graspthesoundtubewhere
it bends. The dome should be
placed far enough into the ear that
the sound tube lies flush with your
head. When the dome is placed
appropriately, you should not see
the sound tube sticking out when
you look directly into a mirror.
• Ifthedevicewhistles,themost
likely reason is that the dome is not
placed correctly in the ear canal.
Other reasons can be buildup of
earwax in the ear canal, or that
the sound tube connection to the
instrument has become loose, in
which case the sound tube must
be changed. It is also possible that
the instrument settings are not
optimal. If you have ruled out other
reasons for the instrument squea-
ling, it is recommended to contact
your hearing care professional.

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.

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 etc. If
program 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:
•onesinglebeepifsetinprogram1
•twobeepsifsetinprogram2
•threebeepsifsetinprogram3
When you close the battery door

Letyourhearingcarepractitionerlloutthefollowingtable:
Directional microphone
BTE and Power BTE can have a directional microphone function.
If you want to listen to a person in a noisy environment, the micro-
phone in these hearing instruments can help you to concentrate
on the speech. If the microphones are in the directional mode the
background noise will be suppressed. In this mode the sounds in
front of you will be enhanced, so you can hear better the speech
of the person you look at. Your hearing care practitioner can
program the device in the required modes.

T-program
Your hearing instrument has 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 (often available in program 2). In this program you will hear
no sounds from the microphone, therefore most environmental
sounds will be lost. If you wish, your hearing care practitioner can
change the setting in such a way that you hear the microphone and
the telecoil simultaneously.
Using the telephone
• Switchyourinstrumenttothetele-
coil program.
• Holdyourtelephonehandsetbe-
hind your ear, close to the hearing
instrument (2-3 cm.) and slightly
tilt the receiver outwards.
• Listentothedialingtoneand
move the handset a little to find
the position that gives the best
reception.
• Ifneeded,turnthevolume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’.

17
Hearing through an induction loop
More and more public places, churches, theatres and cinemas,
have induction loops systems. 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 system.
Sound quality through induction loop is often better because noises
from the environment are not transmitted.
• Switchyourinstrumenttothetelecoilprogram.
• Chooseagoodspot.Receptionisnotclearinalllocations;
it depends on the position of the induction loop. Watch for signs
or try a different seat yourself.
• Ifneeded,adjustthevolumeupordown.
• Aftertheserviceorshow,switchyourinstrumentbacktothe
microphone program. You will now hear through the microphone
again.
• Ifthesoundofyourhearinginstrumentinthetelecoilprogramis
very soft all the time, ask your hearing care practitioner to make
an adjustment.
• Yourhearingcarepractitionerwillgladlyprovideyouwithadvice
regarding an induction loop system at home. Ask for it.

18
Audio input
Your hearing instrument is equipped with a direct audio input
facility. Direct audio input allows direct connection of sound sour-
ces, a radio, television or even school equipment, to your hearing
instrument. Often, this will improve sound quality.
• Thesoundsourceisconnected
to your instrument with a cable or
a wireless FM system to an audio
shoe.
• Theaudioshoeattacheswitha
’click’. When attached, the instru-
ment will automatically switch to
Direct Audio Input program. When
in the is program and the audio
shoe is removed, it will automati-
cally switch to Program 1. You can manually switch away from
this program by pushing the Program Button.
• Inthisprogramyouwillhearnosoundsfromthemicrophone,
therefore most environmental sounds will be lost. If you wish,
your hearing care practitioner can change the setting in such
a way that you hear the microphone and the direct audio input
simultaneously.
Safety regulations
External equipment, connected to the mains and to the audio input
must comply with these safety regulations: IEC-65, IEC-601 or
comparable.

19
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, impairing 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 compart-
ment 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 earmold
• First,removethetubingandear-
mold 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 instructions.
• Rinsetheearmoldwithwater.
Note: Do not use water or other liquid on the hearing instrument
itself.
• Drytheearmoldwithacloth.
• Blowpossiblewaterdropsfrom
tubing and earmold. A special
device is available for this from
your hearing care practitioner.
• Ensurethattheearmoldand
tubing are completely dry before
attaching them to the hearing
instrument. Take care with left and
right instruments, check the figures on page 12.
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.
