Handling batteries
So-called zinc-air batteries are
used today almost exclusively
in hearing instruments to
minimize environmental
damage. These batteries
require oxygen for operation,
which they absorb from the
air. The battery is activated as
soon as the protective foil is pulled off and is used up even
if you do not use your hearing instrument.
You should always pull off the protective foil only if you
actually use the battery. Also, do not leave the batteries
in your hearing instruments if you do not use them over
a longer period. The batteries can leak and damage the
instruments. The batteries keep for from a few days up to
several weeks according to the way they are used. You can
recognize when a change of batteries becomes necessary,
because your hearing instruments become noticeably quieter
towards the end of the battery’s life. Then it is time for new
batteries. Two warning tones sound once per minute, indicating
that you must insert a new battery.
Your hearing instrument specialist can switch off the warning
tones if required.
Zinc-air batteries which are almost completely used up show
the following behaviour: After switching on the instruments
they function completely normally, but then rapidly become
quieter. The more the battery is used up, the faster the gain
falls off. You must then replace such batteries by new ones.

Inserting the battery
Important! Make sure to note the
polarity of the battery!
If the battery is inserted incorrectly,
the battery compartment can be
closed only with considerable
force. This will damage the
instrument.
Closing the battery
compartment
Close the battery compartment by
pressing from below with your
finger tip.
The instrument is switched on.
Up to the first stop = the
instrument is then switched off
Completely open = to change
the battery open the battery
compartment completely by
applying more force
Removing the battery
Open the battery compartment
as shown in the figure.
Normally the battery drops out
when the battery compartment is
completely open.
Should this not be the case, you
can lightly tap the instrument or
push the battery out with a pencil
as shown in the picture.

Three useful tips:
The plus (+) side of the battery is always the smooth
side. You can recognize the minus (–) side by the
coloured ring.
You should always keep spare batteries
at hand.
If you feel you cannot change the battery yourself,
ask someone to help you: a family member, friend
or your hearing instrument specialist.
Please do not throw used batteries into household refuse.
Return them to your hearing instrument specialist for
environmentally correct disposal.
Caution!
Please keep batteries out of the reach of children. They
are damaging to health when swallowed.

Your hearing instrument specialist can program the possible
adjustment range for you. If you do not want to use the
volume control, then your hearing instrument specialist can
also switch it off. Turning the volume control then does not
change the adjustment of your PRISMA 2 D SP hearing
instrument.
PRISMA 2 D SP hearing
instruments are fully automatic. It is therefore not
necessary for you to change
the loudness manually.
However, if you still wish
to do so, PRISMA 2 D SP
offers you a volume control.

For the most frequently required hearing situation e.g. at
home or work place
Switch position 2 - Program "2"
For special situations according to your individual needs, e.g.
music.
Switch position T - Program "3"
For telephoning and for using induction loops e.g. in churches,
theatres or lecture rooms.
Using the "T" position for telephoning requires that the telephone is suitable for hearing instruments and emits a corresponding magnetic field. Not all modern phones, especially
cordless telephones and mobile phones produce a magnet
field. In such cases we recommend that you phone, if possible,
with program "1" or "2".
Switching between the positions 1-T-2 is indicated by beep
tones. One beep tone to position "1", two beep tones to
position "2" and three beep tones to position "T".

Make sure that your hearing
instrument is turned off. The
battery compartment must be
opened up to the stop. Grip the
ear mould between your thumb
and index finger and place the
tip carefully into your auditory
canal.
You may find it helpful to pull
your ear slightly upwards or to
the rear. You may want to push
the ear mould very gently
with your index finger.
Once inserted, you should
feel that the ear mould is
correctly placed.
Now place your hearing
instrument behind your ear
and switch it on. Close the
battery compartment fully.

Tip:
Practice inserting and removing your hearing
instruments correctly.
One easy way to practice is to sit down at a table.
Place a mirror in front of you and prop your elbows
on the table so you can guide your hands easily and
safely. This will help you stay relaxed and comfortable
while you practice.

Notes for cleaning
and care
It is essential to detach the ear mould from your behindthe-ear instrument and place it in a cleaning bath for
at least 15 minutes.
Caution: The hearing
instrument itself cannot
tolerate any moisture.
1.
Bring your hearing instruments regularly to your
hearing instrument
specialist, on the schedule
that he or she recommends,
to have the hearing tube
changed and the instrument checked.
2.
Ear wax accumulates on your ear mould. This can lead to
inflammation in your auditory canal if the instruments are
not cleaned regularly. Therefore:
Page 28
28
Two more tips:
You should place your hearing instruments in a
“dry bag“ with a special moisture-attracting capsule
overnight. The drying capsule draws damaging
moisture out of the instruments.
Your hearing instrument specialist stocks the special
care sets and dry bags you need to maintain your
hearing instruments and keep them in good
condition.
Page 29
29
The best way to handle your
hearing instruments
Your new hearing instruments are highly sensitive
instruments.
This naturally requires some care in their handling.
They should then always give you good service.
Caution!
As with all electrical, non gas-encapsulated instruments,
the hearing instruments must not be operated in
explosion-endangered rooms.

Important tips:
How to solve failures
yourself
In selecting your PRISMA 2 hearing instruments you have
chosen extremely dependable devices. However, should a
fault occur, it can usually be corrected quickly.
If the instrument whistles
Test the instrument yourself by closing the sound
outlet opening with your fingertip.
If the whistling disappears, the instrument is in
order.
Check that the ear mould sits properly in your ear.
Also test the hearing tube for leaks.
If the whistling noise is still audible, only your hearing
instrument specialist can provide assistance.
Sound

Some useful tips:
Never expose your hearing instruments to
extreme temperatures or high humidity.
Never let them lie in the blazing sun. Do not
wear them when taking a shower or when using
hairspray.
In short-wave therapy or if you work or are
medically treated with strong magnetic or
high-frequency fields or X-rays, under no
circumstances may you wear the instruments
during the therapy.
Make sure to switch off the instruments when
not in use. This saves the batteries.
If you don’t wear your instruments for a longer
time, remove the batteries. Batteries can leak
out. Replace batteries that have leaked out
without delay.
If the hearing instrument is too quiet
Most likely, you need to insert a new battery. If it
is still too quiet, clean the instrument or the ear
mould and hearing tube, following the directions
in the chapter
“Notes for cleaning and care“.
If neither a new battery nor cleaning helps,
as a precaution you should ask your hearing
instrument specialist to test your hearing again.
If the hearing instrument does not work at all
Is the instrument turned on? Is the battery
compartment completely closed? Is the battery
inserted correctly? Is it possible that the battery is
dead?
If none of these hints help, you should visit your
hearing instrument specialist.

2nd step
1st step
Hearing training made easy
Hearing instruments reproduce an abundance of sounds
which frequently haven’t been experienced for many years.
Every person reacts differently the first time he or she wears
a hearing instrument. The familiarisation phase therefore
differs from person to person. There are people who are
quite happy to wear their hearing instruments the whole day
long right from the start. Others will regard it as a foreign
body at first. You’ll notice that even after a relatively short
time the positive new hearing experience prevails and you’ll
find your hearing instruments to be something quite normal.
Hearing training helps you here. You’ll become more and
more perfect, and naturally securer, step by step.
Experience sounds outdoors
First choose quiet surroundings for this. For instance, while
taking a stroll you’ll discover all sorts of sounds in the ”silence”
of the forest.
Discover simple sounds in your direct surroundings
Wear your instruments in different situations in different
rooms. Repeat this exercise and you’ll become more
and more familiar with the sounds.
Page 33
All
33
3rd step
Get used to conversations in a group
Conversation in a group of people speaking among
themselves is one of the most difficult hearing
situations. Try to distinguish between the voices by
noting their specific tonal colour and their characteristic
rhythm, and fit them to the individual persons.
Don’t be discouraged and repeat the exercise – think
about your goal: to be able to take part in conversations
again.
Become familiar with your own voice
You’ve already made remarkable progress! You’ve become
much more familiar with the sounds in your daily environment.
As an exercise read out aloud and concentrate on your own
voice.
4th step
Learn to understand the voices of others
Wear the instrument when you speak with someone in your
family. Make a date with a friend. Explain your new situation
and ask the person you’re talking to to speak at a normal
conversational level.
Exercise: Have sentences read out to you and repeat these
sentences.
5th step
6th step
Visit public events
At lectures or in church find a place as close as possible to
the speaker. Also choose a place at the front in theaters and
concert halls. Avoid niches, boxes and places behind pillars.
Page 34
34
8th step
Go on further voyages of discovery – undertake everything that gives you pleasure and experience the whole
wide world of hearing.
7th step
Telephoning with your hearing instrument
You can telephone in the “normal“ M position. Set the switch on the
hearing instrument to T if you have difficulties in understanding. Place
the telephone receiver behind your external ear against the hearing
instrument and find the most favorable and loudest transmission. You
can activate the telephone coil and the microphone by pressing the
program button so that you can hear the normal surroundings.
Your hearing instrument fulfils the IEC 118-13 standard
with regard to electromagnetic compatibility (concerning
for example interference by external radiotelephones).
If you use a radiotelephone (GSM) yourself, unfortunately
unavoidable disturbances can occur in your hearing
instrument under certain circumstances because of the
high field strengths.
This is certainly unpleasant but no reason for concern.
Your hearing instrument isn’t defective.

We’re happy that you
can hear well again!
Once good hearing returns to
your everyday life – and you can
enjoy both speech and music
again – then we at Siemens are
also satisfied.
Because we’ve put all our
knowledge and skill into developing
your hearing instruments!
