The device consists of:
• A triangular amplifier unit, which holds the
microphones and the battery. The amplifier unit
sits comfortably and discreetly behind the ear.
• A speaker unit where a thin tube connects the
speaker with the amplifier. The speaker sits in the
ear canal and delivers sound directly into the ear.
• An optional ear grip, which follows the contour of
the ear and ensures that the speaker and the whole
device is securely fastened.
• An ear piece, a dome (A) or a custom made Micro
Mould (B), which holds the speaker comfortably in
the ear. It also protects the speaker against ear wax.

Product case
When you are not using your devices, place them in
the product case. Ensure that the battery doors are
open, when you place the devices in the case.

10 11
Putting on the devices
Turn the device on. Place the speaker, with the ear
piece attached, into your ear first and then place the
amplifier behind your ear. If the instrument comes
with a Micro Mould, make sure that the coloured
dot (blue or red) on the mould is facing towards the
amplifier unit (upwards) to ensure a correct position
in the ear canal.
Make sure that the ear piece is placed so that the
tube follows the contour of the skin.
If the instrument has an ear grip, place it in the con-
cha as indicated in drawing 4.
Alternatively place the amplifier behind your ear.
Put the speaker into your ear canal.

Daily maintenance – Domes
Clean the speaker unit daily. Use a dry cloth and rub
off any earwax.
The dome should not be cleaned. When you require
a fresh, clean dome, remove the existing one and put
on a fresh one.
We recommend the dome to be replaced at least
once a month or as directed by your Hearing Care
Professional.

14 15
Changing the dome
The dome is easy to replace. Replace it whenever
needed. Use a fingernail and hold the bottom of
the dome. Then pull it off. Place the new dome on
the speaker and ensure that it is fastened securely.
Throw out the old dome.
Under the dome you will notice a white wax filter
attached to the end of the speaker. This is a wax filter
that will keep debris from damaging the speaker. If
this filter becomes clogged, contact your Hearing
Care Professional for service and replacement of the
filter.
Note: The dome is made of a soft, medically approved rubber
material. If the dome comes off in the ear canal, it will not
cause any harm. If you can – carefully take it out. Maybe
let another person help you. Do not push the dome into the
ear canal. If you have any doubts, contact your Hearing Care
Professional.

Daily maintenance – Micro Moulds
Clean the speaker unit and Micro Moulds daily.
Use a dry cloth and rub off any ear wax.
Note. The hearing devices and the Micro Moulds
must never be washed.
Your ear canal produces ear wax (cerumen) which
may clog up the sound outlet or the ventilation
opening. Therefore your hearing devices contain
filters to prevent wax accumulation.
Clean away any traces of wax from around the
ventilation opening. Use the special cleaning tool
provided by your Hearing Care Professional.

Warnings
You should familiarize yourself fully with the
following general warnings and the entire contents
of this booklet before using your hearing devices.
Hearing devices can be dangerous if used improperly.
Such actions can result in severe injury, permanent
hearing loss, or can even be fatal.
Hearing devices and batteries can be dangerous
if swallowed
• Hearing devices, their parts, and batteries are not
toys and should be kept out of reach of children
and anyone who might swallow these items or
otherwise cause injury to themselves.
• Never change the battery or adjust the controls
of the hearing devices in front of infants, small
children or people with learning difficulties.

• Discard batteries carefully in a place where infants,
small children or people with learning difficulties
cannot reach them.
• Batteries have occasionally been mistaken for pills.
Therefore carefully check your medicine before
swallowing any pills.
• Never put your hearing devices or batteries in your
mouth for any reason, as they are slippery and
could be swallowed by accident.
• Some Oticon hearing devices can be supplied
with a tamper-resistant battery compartment
upon request. This is strongly recommended for
infants, small children, and people with learning
difficulties.
• If a battery or hearing device is swallowed, see a
doctor immediately.
Use the device as instructed by your Hearing
Care Professional
• Hearing devices should be used only as directed
and adjusted by your Hearing Care Professional.
Misuse could result in sudden and permanent
hearing loss.
Battery use
• Always use batteries recommended by your
Hearing Care Professional. Batteries of low quality
may leak and cause bodily harm.
• Never attempt to recharge your batteries. They may
explode and cause serious injury.
• Never dispose of batteries by burning them. There
is a risk that they will explode and cause serious
injury.

Dysfunction in hearing devices
• Hearing devices may stop functioning, for instance
if the batteries have expired or if the receiver/loud-
speaker is blocked by moisture or earwax. You
should be aware of this possibility, in particular
when you are in traffic or otherwise dependent on
warning sounds.
Interference
• Your hearing devices have been thoroughly tested
for interference, according to the most stringent
international standards. But new technical
developments constantly bring new products
into society, and some may emit electromagnetic
radiation, leading to unforeseen interference in
hearing devices. Examples include induction
cooking appliances, shop alarm systems, mobile
telephones, fax machines, personal computer
devices, X-rays, Computer tomography, etc.
Possible side effects
• Hearing devices may cause an accelerated
accumulation of cerumen (earwax).
• The otherwise non-allergenic materials used in
hearing devices may in rare cases cause a skin
irritation.
Consult a doctor if you experience any of these side
effects.

Wax protection system
• Always visually inspect your hearing devices to
ensure that there is no gap between the wax
protection flange and the tip of the Micro Mould.
If you are in any doubt about the use or replacement
of your wax protection system, contact your Hearing
Care Professional.

Replace the wax protection system
1. Remove the tool from the shell. The tool has two
ends, one with the new filter (A) and one with the

3. Pull the used wax filter out slowly keeping the tool
straight.
4. Turn the tool 1800.

The wax filter should be changed:
• When you can see that the filter placed in the
Micro Mould is clogged,
or
• When the hearing device does not sound normal.
(If this is the case, please check the filter in the
Micro Mould to see if it is clogged.)
DO NOT USE OTHER WAX PROTECTION
SYSTEMS ON THE DEVICES.

22 23
Changing batteries
When the batteries is low, you will hear a short
series of beeps. Remove the sticky label from a fresh
battery. Insert the new battery with the +marking
facing the +marking on the battery door. Close the
battery door. It will take a few seconds before the
battery works to full capacity.

24 25
Daily use and care
The devices are designed to deliver improved
understanding, especially in noisy surroundings.
We do recommend that you wear them all day. In the
beginning, you will hear new sounds that you have
not heard for a while. You quickly get used to your
devices, and in quiet surroundings, they should not
be uncomfortable or loud.
In group situations, try to focus on the person you
want to hear. Position yourself in front of the person
you want to communicate with. If you miss a word,
ask the person to repeat it.
Using the telephone
If your instruments have domes, you may place the
receiver directly over your ear canal to let the sound
from the phone enter directly into your ear.
If you are using devices with Micro Moulds you
should tilt the receiver edge lightly on your cheek-
bone in order to let the sound flow directly into the
hearing device’s microphone opening.
Even though your new devices are designed to
comply with the strictest “Standards of International
Electromagnetic Compatibility”, not all mobile
phones are fully compatible and might introduce
some interference.
Avoid heat, humidity and chemicals. Your devices
should not be exposed to extreme heat, e.g. left
inside a car parked in the sun. They should not be
worn in the shower, during swimming or in heavy
rain. And they should not be dried in a microwave
or normal oven. Please be aware that chemicals used
in cosmetics, hair spray, perfume, after shave and
suntan lotion, etc. may damage your devices.
