Intended use
A Hearing aid can be adjusted across all sound frequencies to
help anyone cope with hearing loss. Personal uncomfortable
sound levels are measured so that an individualise setting can be
programmed to enhance speech clarity in both quite and noisy
environment which will greatly reduce listening eort.
The hearing aids are typically designed to last for up to
6 years. Factors aecting the lifespan of the aid are listed in .
the Safety Instructions for use guide.
All Hearing aids including a Tinnitus noiser function must be
individually fitted by a Hearing Care professional or an ENT

 INTRODUCTION
Congratulations on the purchase of your new audifon hearing
aids. Your hearing care professional has set this for your individual
requirements. These instructions are therefore intended to help
you use your audifon hearing aids properly.
Please read through the following operating and care
instructions carefully to avoid malfunctions and damage. If you
follow the instructions, your hearing aids will prove an invaluable
help in day-to-day communication in your surroundings and with
other people.
The specific model of your hearing aids is shown on the sticker on
the packaging, on the warranty card or printed on the the body of
the hearing aid.
A hearing aid cannot restore your hearing to normal or cure
your hearing loss and neither will it make your hearing worse.
However, a hearing aid will go a long way to restoring normal
hearing levels for many of those activities you may have been
missing out on. Hearing aids are the treatment of choice for most
types of hearing loss.
If you have any further questions, please contact your hearing
care professional.

.. Information on battery
A zinc air battery is used to supply power for your hearing aids.
This type of battery is only activated when oxygen comes
through the air holes into the button cell and a chemical
reaction is initiated. During production, the air holes are
sealed with a protective strip. This means that the battery
remains fresh until use, and it lasts longer when it is sealed.
Removing the protective strip allows oxygen to enter and the
chemical reaction is initiated.
Refitting the strip when the battery is not in use will not
extend its service life.
Battery should be stored at room temperature.
Avoid keeping them in hot places or rooms with high
humidity (e.g. bathroom). Storage in a cooled location is not
necessary.
Used batteries are considered hazardous materials and
contain toxic materials, should never be disposed of in the
trash. Ask about recycling programs in your area where
you live or return them to your hearing care professional to
dispose them appropriately.
Further safety instructions can be found on the battery
packaging.
.. Low battery warning
audifon hearing aids are equipped with a low battery signal
which can be heard as a series of beeps approximately
30 minutes before the end of the battery life. The wireless
function will be switched o, when the battery becomes empty.

 CARE INSTRUCTIONS
. General
audifon hearing aids will improve your hearing ability as well
as your quality of life. To ensure your hearing aids function
perfectly and so make hearing a pleasant experience for years
to come, audifon oers special care products designed to enable
optimum cleaning of your devices.
Protect your hearing aids against moisture (e.g. showers, sweat,
rain), and take your hearing aids out before using hairspray or
similar cosmetic products.
No matter what type of hearing aid you use, we also recommend
carrying out daily care on them as these devices are exposed to
moisture and dust through intended use, even when handled
with care: Each one is in direct contact with the skin. Resulting
perspiration may damage your hearing aid in the long term
unless dried on a daily basis. audifon’s behind-the-ear hearing
aids are coated with a water-repellent finish to prevent any
damage from moisture.
Wearing a hearing aid or inserting the ear adapter piece in the
ear canal will always involve soiling with earwax. For this reason
we recommend regular cleaning. Do not use a damp cloth to
clean your hearing aids. Always use a soft, dry cloth.
Should your hearing aid still not function correctly despite
regular care, call on your hearing care professional. Do not try
under any circumstances to repair your hearing aid yourself.
3130
The hearing aids belonging to the lewi and risa families are
compatible with standard smartphones equipped with
Bluetooth version 4.0 or higher. The MULTISTREAMER PRO
accessory may be required for audio transmission
(e.g. for smartphones with an Android operating system).
For a list of smartphones, tablets etc. that are compatible with
the hearing aids in the lewi and risa ranges and the audifon App,
please visit:
www.audifon.com
. Intended use of the dome
audifon domes are an accessory available for audifon hearing
aids and noisers. They are part of the replaceable sound
transmission system (receiver module and ThinTube) and keep
the sound tube and receiver module in position within ear canal,
thereby contributing to securing the hearing aid and noiser
within the ear.

. Cleaning
The ear adapter pieces and the flexible
plastic tubing attached to them must
be detached from the ear hook before
cleaning. Only use the recommended
care products for cleaning the ear adapter
pieces.
In the case of hearing aids with a thin
sound tube, the plug connection between
the tube and hearing aid can be detached.
The dome is removed for cleaning.
Ear adapter piece
UniTip ThinTube
7.4 Daily care
Regular cleaning and care of your hearing aids will significantly
prolong their life and increase the time between repairs.
You can obtain a “pro care” cleaning and care program from your
audiologist; this program will be specially designed for your type
of hearing aid.
We recommend the use of “pro care” cleaning cloths for daily
cleaning of your hearing aid. Be sure to remove any ear wax
adhering to the hearing aid. If you need a clean new dome,
simply replace the old dome with a new one. You can obtain a
suitable dome from your audiologist. For this, see Section 7.3
Changing the dome.
Use an audifon drying system for daily drying of your hearing
aids. This makes an eective contribution to avoiding damage to
your hearing aids.
. Changing the dome
It is easy to change the dome if required.
Use your finger nail to hold the lower end of the dome, and pull
the dome o. Then fit the new dome to the receiver. Make sure
you slide it far enough on to the receiver. Dispose of the old dome.
The dome is made of soft silicone, approved for medical use.
It must be changed regularly, depending on the frequency of use.
We recommend it is changed at least once a month.

 TROUBLESHOOTING
If you experience any malfunctions when using your hearing
aids, this does not necessarily mean that they are faulty.
Therefore please first check your hearing aid to make sure that:
•the hearing aid is switched ON (see
"Switching ON and OFF" Section 3.4),
•the batteries are not weak or dead,
•the volume control is not at the lowest setting
(increase the volume slightly if necessary),
•the right program has been set
(change program if necessary),
•the receiver unit / earwax protection system is not blocked.
If this does not eliminate the fault, consult your hearing
care professional, who will be pleased to help.
Note: Malfunctions!
Your devices may be subject to interference from other
electrical equipment despite their EMC-compatible design.
In this case move away from the source of interference.
Warning: Risk of suocation!
Batteries, hearing aids and other small parts can be
swallowed. For this reason, these hearing aids are not
intended for use by children under 36 months of age.
Never leave children unattended with your hearing aids!
Should a battery, hearing aid or other small parts be
accidentally swallowed, please consult a doctor immediately.
Warning: Risk of injury!
In some very rare cases the dome may remain in the
ear canal on removal. Should this happen, please
contact your doctor or hearing care professional at
once. Please do not try to remove the dome yourself.
Warning: Damage to hearing!
The maximum volume of the noiser modul is in a
range that may lead to hearing loss according to OSHA
regulations. For users without hearing loss, the noiser
modul should not exceed sound pressure levels above
70 dB SPL (as measured at a 2cc coupler). For users
with hearing loss, the hearing loss needs to be taken
into consideration when adjusting the noise levels.
Under no circumstances should the noiser module be
used at a volume that is uncomfortable to the user.
For sound pressure levels up to 80 db SPL (as measured
at the 2cc coupler) the noiser module can be used for
up to 8 hours daily. For higher sound pressure levels,
the uncritical duration of applications is reduced.
The noiser modul should not be used for more than
2 hours daily at higher sound pressure levels.
 SAFETY INFORMATION
. Important warnings
3534

Higher sound levels and/or longer times of application
might harm the hearing ability over time.
Warning: Risk of explosion!
Do not use hearing aids in environments where
there is a risk of explosion (e.g. in mines or
industrial plants subject to such risk).
Warning: Risk of injury!
Hearing aids are adjusted to the individual hearing loss
of each wearer and should therefore only be used by this
person.
If the hearing aid is worn by other persons, this may harm
their hearing.
Warning: Risk of injury!
Please only use genuine consumables specified by the
manufacturer (dome, tubing, etc.) and accessories.
Unauthorised changes or modifications that have not been
explicitly approved may in the worst-case scenario result in
injur y.
Warning: Interference with active and inactive
implants!
If you have an active or inactive implant (e.g. defibrillator,
pacemaker), follow the implant manufacturer's instructions
