Caring for your hearing instrument
Your ear canal produces ear wax (cerumen) which
may clog up the earpiece. Therefore your hearing
instrument contains
a filter to prevent wax accumulation. Consult your
Hearing Care Professional for instructions about the
specific wax protection system in your hearing
instrument and how it can be replaced.
When handling a hearing instrument, keep it over a
soft surface to avoid damage if you drop it.
Before retiring at night:
Make sure that there is no ear wax in any of the•
earmold openings since it may reduce the hearing
instrument’s efficiency.
Open the battery door to allow air to circulate.•
Cleaning the instrument
A range of dedicated cleaning tools is prepared for the
special purpose of cleaning the instrument. These
should be used to ensure the best care and perform-
ance of your hearing instruments.
Use the cloth to wipe clean the surface of the
instruments.
Replace the brush when necessary. Just pull it out of
the tool and insert a new fresh brush. Press the new
one firmly into the handle.

Warnings
Hearing instruments and batteries can be dangerous
if swallowed or used improperly. Such actions can
result in severe injury, permanent hearing loss, or
can even be fatal.
You should familiarize yourself fully with the follow-
ing general warnings and the entire contents of this
booklet before using your hearing instruments.
Hearing instruments should be used only as•
directed and adjusted by your trained Hearing
Specialist. Misuse can result in sudden and
permanent hearing loss.
Hearing instruments, 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 instrument 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 instruments or batteries in•
your mouth for any reason, as they are slippery
and could be swallowed by accident.
Most hearing instruments can be supplied with a•
tamper-resistant battery compartment upon
request. This is strongly recommended for infants,
small children, and people with learning difficulties.
Never allow others to wear your hearing instru-•
ments as incorrect/wrongful usage could cause
permanent damage to their hearing.
If a battery or hearing instrument is swallowed, see a
doctor immediately and call the National Poison
Center, collect [phone].
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 instruments
Hearing instruments may stop functioning, for•
instance if the batteries have expired or if the
tubing 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.
Warning to hearing instrument dispensers
A hearing instrument dispenser should advise a
prospective hearing instrument user to consult
immediately with a licensed physician (preferably an
ear specialist) before dispensing a hearing instru-
ment. If the hearing instrument dispenser deter-
mines through inquiry, actual observation, or review
of any other available information concerning the
prospective user, that the prospective user has any
of the following conditions:
(i) Visible congenital or traumatic deformity of the
ear.
(ii) History of active drainage from the ear within
the previous 90 days.
(iii) History of sudden or rapidly progressive hearing
loss within the previous 90 days.

(iv) Acute or chronic dizziness.
(v) Unilateral hearing loss of sudden or recent nset
within the previous 90 days.
(vi) Audiometric air-bone gap equal to or greater
than 15 decibels at 500 Hertz (Hz), 1,000 Hz,
and 2,000 Hz.
(vii) Visible evidence of significant cerumen accu-
mulation or a foreign body in the ear canal.
(viii) Pain or discomfort in the ear.
Special care should be exercised in selecting and
fitting a hearing instrument whose maximum sound
pressure capability exceeds 132 dB SPL as there may
be risk of impairing the remaining hearing of the
hearing instrument user.
Important notice for prospective
hearing instrument users
Good health practice requires that a person with a
hearing loss have a medical evaluation by a licensed
physician (preferably a physician who specializes in
diseases of the ear) before purchasing a hearing
instrument. Licensed physicians who specialize in
diseases of the ear are often referred to as Otolaryn-
gologists, Otologists or Otorhinolaryngologists. The
purpose of medical evaluation is to ensure that all
medically treatable conditions that may affect
hearing are identified and treated before the hearing
instrument is purchased. Following the medical
evaluation, the physician will give you a written
statement that states that your hearing loss has
been medically evaluated and that you may be
considered a candidate for a hearing instrument.
The physician will refer you to an audiologist or a
hearing instrument dispenser, as appropriate, for a
hearing instrument evaluation.
The audiologist or hearing instrument dispenser will
conduct a hearing instrument evaluation to assess
your ability to hear with and without a hearing instru-
ment. The hearing instrument evaluation will enable
the audiologist or dispenser to select and fit a
hearing instrument to your individual needs. If you
have reservations about your ability to adapt to
amplification, you should inquire about the avail-
ability of a trial, rental or purchase-option program.
Many hearing instrument dispensers now offer
programs that permit you to wear a hearing instrument
for a period of time for a nominal fee, after which
you may decide if you want to purchase the hearing
instrument. Federal law limits the sale of hearing
instruments to those individuals who have obtained
a medical evaluation from a licensed physician.
Federal law permits a fully informed adult to sign a
waiver statement declining the medical evaluation
for religious or personal beliefs that preclude
consultation with a physician.

The exercise of such a waiver is not in your best
health interest and its use is strongly discouraged.
A hearing aid will not restore normal hearing and will
not prevent or improve a hearing impairment result-
ing from organic conditions. A hearing aid is only
part of hearing rehabilitation and may need to be
supplemented by auditory training and lip reading.
Interference
Your hearing instrument has been thoroughly•
tested for interference, according to the most
stringent international standards. But new techni-
cal developments constantly bring new products
into society, and some may emit electromagnetic
radiation, leading to unforeseen interference in
hearing instruments. Examples include induction
cooking appliances, shop alarm systems, mobile
telephones, fax machines, personal computer
devices, X-rays, computer tomography etc.
Your hearing instruments are designed to comply•
with the most stringent Standards of International
Electromagnetic Compatibility. However, your
hearing instrument may cause interference with
other medical devices. Such interference can also
be caused by radio signals, power line disturbanc-
es, airport metal detectors, electromagnetic fields
from other medical devices and eletcrostatic
discharges.
Possible side effects
The hearing aid or earmold is a custom-made
product. If you are experiencing discomfort, see your
audiologist or hearing instrument dispenser immedi-
ately for modification of the hearing instrument or
earmold at the point of irritation. A hearing instru-
ment or earmold may cause an accelerated accumu-
lation of cerumen (earwax). Also in rare cases, the
otherwise non-allergenic material may cause a
discharge from the ear, allergic reaction, or any other
unusual condition. Please seek immediate consulta-
tion with a physician if these conditions occur.
Children with hearing loss
In addition to seeing a physician for medical evalua-
tion, a child with a hearing loss should be directed
to an audiologist for evaluation and rehabilitation,
since hearing loss may cause problems in language
development, educational and social growth of a
child. An audiologist is qualified by training and
experience to assist in the evaluation and rehabilita-
tion of a child with a hearing loss. If the user is an
infant, small child or person of mental incapacity, it is
recommended that the hearing instrument be modi-
fied with a tamper-resistant battery compartment.

Wax protection system
Always visually inspect your hearing instruments•
to ensure that there is no gap between the wax
protection flange and the tip of the Mold.
Improper placement of your wax protection system
may cause it to become dislodged or fall out in your
ear.
If you are in any doubt about the use or replacement
of your wax protection system, contact your Hearing
Care Professional.

Daily maintenance with domes
Clean the speaker unit daily. Use the cloth and rub
off any earwax.
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.

Changing the dome
The dome is easy to replace. Use a finger nail 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.

 
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 replace-
ment of the filter.
Important Notice
The dome is made of a soft, medically approved
material. If the dome comes off in the ear canal, it
will not cause any harm. If you can – carefully take
it out. If necessary, let another person help you. Do
not push the dome into the ear canal. Do not push
the speaker unit into the ear again before the dome
is removed from the ear. If you have any doubts,
contact your Hearing Care Professional.
Avoiding heat, humidity and chemicals
Your hearing instrument must never be exposed to
extreme heat e.g. left inside a parked car in the sun.
They must never be exposed to a lot of moisture e.g.
steam baths, showers or heavy rain. Nor must they
be dried in microwave ovens or other ovens.
Wipe the batteries carefully if moisture is present
as it may affect their performance. Using an anti-
humidity kit can help to avoid these problems and
may even extend the life of your hearing instrument.
Consult your Hearing Care Professional for further
advice.
The chemicals in cosmetics, hairspray, perfume,
aftershave lotion, suntan lotion and insect repellant
can damage your hearing instrument. You should
always remove your hearing instrument before
applying such products and allow time for the
product to dry before reinserting your hearing
instrument. If you use lotion, be sure to wipe your
hands dry before putting on your hearing instrument.

Using your hearing instrument
It takes time to adjust to a new hearing instrument.
How long this adjustment takes differs from person
to person. It will depend on a number of factors,
such as whether you have had a hearing instrument
before and the degree of your hearing loss.
Six easy steps to better hearing
1. In the quiet of your home
Try to accustom yourself to all the new sounds.
Listen to the many background sounds and try to
identify each sound. Bear in mind that some sounds
will seem different from what you are used to. You
may have to learn to identify them again. Note that
in time you will get accustomed to the sounds in
your environment – if not please contact your
Hearing Care Professional.
If using the hearing instrument makes you tired, take
them off for a little while and have a rest. Gradually,
you will begin to be able to listen for longer periods
of time. Soon, you will be able to wear your hearing
instrument comfortably all day long.
. Conversation with another person
Sit with someone else in a quiet room. Face each
other so you can read facial expressions easily. You
may experience new speech sounds, which can
seem a little disturbing in the beginning. However,
after the brain has adapted to the new speech
sounds, you should hear speech more clearly.
. Listen to radio or TV
When listening to the TV or the radio, start out by
listening to news commentators since they usually
speak clearly, then try other programs.
If you find it difficult to listen to TV or radio, your
Hearing Care Professional should be able to give you
advice on available accessories to enhance your
listening capabilities for TV and radio.
4. In group conversations
Group situations are usually accompanied by a
greater degree of background noise and are naturally
more difficult to cope with. In such situations, focus
your attention on the person you want to hear. If you
miss a word, ask the speaker to repeat.

 
6. Using the telephone
When using the telephone tilt
the receiver edge lightly on your cheek-bone and
position the phone slightly over the ear close to the
hearing instrument’s microphone. The sound then
flows directly into the hearing instrument’s micro-
phone opening. This way, the hearing instruments
will not whistle and you ensure the best conditions
to understand the conversation. When you have the
receiver in this position, remember to speak directly
into the mouthpiece on the telephone in order to
ensure good understanding on the other “end of the
line”.
Your hearing instrument has an AutoPhone. Your
instrument can be set to automatically switch into a
phone program in order to improve the sound
reception further.
Remember that the telecoil in hearing instruments
may pick up unwanted signals from electronic
devices, such as fax machines, computers or
televisions. Make sure that the hearing instrument is
 to 10 feet from such devices when using the
telecoil program.
6. Wireless and cell phones
Your hearing instrument is designed to comply with
the most stringent Standards of International
Electromagnetic Compatibility. However not all cell
phones are hearing instrument compatible. The
varying degree of disturbance can be due to the
nature of your particular cell phone.
If you find it difficult to obtain a good result while
using your cell telephone, your Hearing Care Profes-
sional should be able to give you advice
on available accessories to enhance listening
capabilities.
