Warnings
Changes or modications to the hearing
aids that are not explicitly approved by
the manufacturer are not permitted. Such
changes may damage your ear or the hearing
aids.
The intended use of hearing aids is to
amplify and transmit sound to the ears and
hereby compensate for impaired hearing.
The hearing aids (specially programmed for
each hearing loss) must only be used by the
intended person. They should not be used
by any other person as they could damage
hearing.
Hearing aids should only be used as
directed by your physician or hearing care
professional.
Hearing aids will not restore normal
hearing and will not prevent or improve a
hearing impairment resulting from organic
conditions.
Do not use your hearing aids in explosion
hazard areas.
Allergic reactions to hearing aids are
unlikely. However, if you experience itching,
redness, soreness, inflammation or a burning
sensation in or around your ears, inform your
hearing care professional and contact your
physician.
In the unlikely case that any parts remain in
the ear canals aer the removal of the hearing
aids, contact a physician immediately.
Hearing programs in the directional
microphone mode reduce background noises.
Please be aware that warning signals or
noises coming from behind, e. g. cars, are
partially or entirely suppressed.
These hearing aids are not for children
below 36 months. The usage of this device
by children and individuals with cognitive
impairment should be supervised at all times
to ensure their safety. The hearing aids are
small devices and contain small parts.

6 7
Do not leave children and individuals with
cognitive impairment unsupervised with
these hearing aids. If swallowed, consult
a physician or hospital immediately as
the hearing aids or their parts can cause
choking.
Do not make a wire connection from your
hearing aids to any external audio sources
like radio etc. That could cause injuries on
your body (electric shock).
The following is only applicable for persons
with active implantable medical devices
(i.e. pacemakers, debrillators, etc.):
- Keep the wireless hearing aids at least 15
cm (6 inches) away from the active implant.
- If you experience any interference, do not
use the wireless hearing aids and contact
the manufacturer of the active implant.
Please note that interference can also
be caused by power lines, electrostatic
discharge, airport metal detectors etc.
Special medical or dental examination
including radiation described below, may
adversely aect the correct functioning of
your hearing aids. Remove and keep them
outside the examination room/area before
undergoing:
- Medical or dental examination with X-ray
(also CT scan).
- Medical examinations with MRI/NMRI
scans, generating magnetic elds.
- Hearing aids don’t need to be removed
when passing security gates (airports etc.).
If X-ray is used at all, it will be in very low
doses, and will not aect the hearing aids.
Use of this equipment adjacent to or
stacked with other equipment should be
avoided because it could result in improper
operation. If such use is necessary, this
equipment and the other equipment should
be observed to verify that they are operating
normally.

8 9
Use of accessories, transducers and cables
other than those specied or provided
by the manufacturer of this equipment
could result in increased electromagnetic
emissions or decreased electromagnetic
immunity of this equipment and result in
improper operation.
Your hearing aids operate in the frequency
range of . GHz–.8 GHz. When flying
please check if flight operator requires
devices to be switched into flight mode.
Portable RF communications equipment
(including peripherals such as antenna
cables and external antennas) should be
used no closer than 30 cm (12 inches) to
any part of the hearing aids, including
cables specied by the manufacturer.
Otherwise, degradation of the performance
of this equipment could result.
Special care should be exercised in wearing
hearing aids when maximum sound
pressure levels exceed 132 decibels. There
may be a risk of impairing your remaining
hearing. Speak with your hearing care
professional to ensure the maximum output
of your hearing aids is suitable for your
particular hearing loss.
Note to hearing care professional
Domes should never be tted on clients with
perforated eardrums, exposed middle ear
cavities, or surgically altered ear canals. In
the case of such a condition, we recommend
to use a customized earmold.
Battery warnings
Never leave hearing aids or batteries
where small children and pets can reach
them. Never put hearing aids or batteries
in your mouth. If a hearing aid or battery is
swallowed, call a physician immediately.

10 11
Precautions
These hearing aids are water resistant
and not waterproof. They are designed to
withstand normal activities and occasional
accidental exposure to extreme conditions.
Never immerse your hearing aids in water.
These hearing aids are not specically
designed for extended periods of water
submersion on a continual basis, that is
worn in activities such as swimming or
bathing. Always remove your hearing aids
before these activities, as the hearing aids
contain sensitive electronic parts.
Protect your hearing aids from heat (never
leave near a window or in the car). Never
use a microwave or other heating devices
to dry your hearing aids (due to risk of
re or explosion). Ask your hearing care
professional about suitable drying methods.
The dome should be changed every three
months or when it becomes sti or brittle.
This is to prevent the dome from detaching
from the tube spout during insertion into or
removal from the ear.
Do not drop your hearing aids. Dropping
onto a hard surface can damage your
hearing aids.
The use of hearing aids is only part of
hearing rehabilitation; auditory training and
lip reading instruction may be required as
well.
In most cases, infrequent use of hearing
aids does not provide full benet. Once you
have become accustomed to your hearing
aids, wear your hearing aids everyday all
day.
Your hearing aids use the most modern
components to provide the best possible
sound quality in every listening situation.
However, communication devices such
as digital mobile phones can create

12 13
interference (a buzzing sound) in hearing
aids. If you experience interference from a
mobile phone being used close by, you can
minimize this interference in a number of
ways. Switch your hearing aids to another
program, turn your head in a dierent
direction or locate the mobile phone and
move away from it.
Labeling
The serial number and year of manufacture are
located inside the battery door.
Mobile phone compatibility rating
Some hearing aid users have reported a buzzing
sound in their hearing aids when they are using
mobile phones, indicating that the mobile
phone and hearing aids may not be compatible.
According to the ANSI C63.19 standard (ANSI
C63.19-2011 American National Standard
Methods of Measurement of Compatibility
Between Wireless Communications Devices and
Hearing Aids), the compatibility of particular
hearing aids and a mobile phone can be
predicted by adding the rating for the hearing
aid immunity to the rating for the mobile phone
emissions. For example, the sum of the hearing
aid rating of 4 (M4) and a telephone rating of 3
(M3) would result in a combined rating of 7. Any
combined rating that equals at least 5 would
provide “normal use”; a combined rating of 6 or
greater would indicate “excellent performance.”
The immunity of these hearing aids is at least
M4. The equipment performance measurements,
categories and system classications are based
upon the best information available but cannot
guarantee that all users will be satised.

14 15
The performance of the individual hearing
aids may vary with individual mobile phones.
Therefore, please try these hearing aids with
your mobile phone or, if you are purchasing a
new phone, please be sure to try it with your
hearing aids prior to purchase.
Tinnitus masker
Tinnitus masker uses broadband noise to
provide temporary relief of tinnitus.
Tinnitus masker warnings
The tinnitus masker is a broadband sound
generator. It provides a means of sound
enrichment therapy that can be used as
part of a personalized tinnitus management
program to provide temporary relief from
tinnitus.
The underlying principle of sound
enrichment is to provide supplementary
noise stimulation which can help defocus
your attention from your tinnitus and avoid
negative reactions. Sound enrichment,
coupled with instructional counseling, is an
established approach to managing tinnitus.
Air conduction hearing aids with the tinnitus
masker are to be tted by a hearing care
professional familiar with the diagnosis and
management of tinnitus.

16 17
Should you develop any side eects
while using the tinnitus masker, such as
headaches, nausea, dizziness or heart
palpitations or experience a decrease
in auditory function such as decreased
loudness tolerance, worsening of tinnitus, or
speech not as clear, you should discontinue
use of the device and seek medical
attention.
The volume of the tinnitus masker can be
set to a level which could lead to permanent
hearing damage when used for a prolonged
period of time. Should the tinnitus masker
be set to such a level in your hearing aids,
your hearing care professional will advise
you of the maximum amount of time per day
you should use the tinnitus masker.
The tinnitus masker should never be used at
uncomfortable levels.
Important information
The tinnitus masker generates sounds
that are used as part of your personalized
temporary tinnitus management program
to provide relief from tinnitus. It should
always be used as prescribed by a hearing
care professional who is familiar with the
diagnosis and treatment of tinnitus.
Good health practice requires that a person
reporting tinnitus have a medical evaluation
by a licensed ear physician before using
a sound generator. The purpose of such
an evaluation is to ensure that medically
treatable conditions, which may be causing
tinnitus, are identied and treated prior to
using a sound generator.
The tinnitus masker is intended for adults
18 years of age or older who have both
hearing loss and tinnitus.

Battery information
Low battery warning
Two long beeps indicate the hearing aid battery
is low. Aer the low battery warning, sounds
may not be as clear. This is normal and can be
xed by changing the batteries.
If you can’t hear the low battery warning, your
hearing care professional can change its pitch
or loudness. If you prefer, it can be turned o
entirely.
Your hearing aids are designed to generate a
low battery warning every 30 minutes until you
change the batteries, but depending on the
condition of the batteries, they may die before
another low battery warning occurs. Therefore,
it is recommended that the batteries are
replaced as soon as possible once you hear the
low battery warning.

20 21
Replacing the battery
1. Gently swing out the battery
door with your ngernail.
2. Push the battery with your
thumb and index nger towards
the open side, and remove or
pull the battery straight out,
depending on your style of
hearing aid.
3. Insert the new battery into the
battery compartment with the
plus (+) sign on the battery
facing the same way as the
battery symbol on the battery
door. This will ensure that the
battery door closes properly.
Note: If the battery is inserted
incorrectly, the hearing aid will not
turn on.
4. Close the battery door.
