following general warnings and the entire
contents of this booklet before using your
hearing aid to ensure personal safety and correct
use.
Contact your hearing care professional if you
experience unexpected operations or events with
your hearing aid.
Please note that a hearing aid will not restore
normal hearing and will not prevent or improve a
hearing impairment resulting from organic
conditions. Furthermore, note that in most cases,
infrequent use of a hearing aid does not permit a
user to attain full benefit from it.
28
General warnings
Usage of hearing aids
·· Hearing aids should be used only as directed
and adjusted by your hearing care professional.
Misuse can result in sudden and permanent
hearing loss.
·· Never allow others to wear your hearing aid as
incorrect usage could cause permanent
damage to their hearing.
Choking hazards & risk of swallowing batteries and other
small parts
·· Hearing aids, their parts, and batteries should
be kept out of reach of children and anyone
who might swallow these items or otherwise
cause injury to themselves.
·· Batteries have occasionally been mistaken for
pills. Therefore, check your medicine carefully
before swallowing any pills.

There is a risk that the batteries will explode.
Dysfunction
·· Be aware of the possibility that your hearing aid
may stop working without notice. Keep this in
mind when you depend on warning sounds
(e.g., when you are in traffic). The hearing aids
may stop functioning, for instance if the
batteries have expired or if the tubing is
blocked by moisture or ear wax.
Active implants
·· Caution must be taken with active implants. In
general, follow the guidelines recommended by
manufacturers of implantable defibrillators and
pacemakers regarding use with mobile phones
and magnets.
·· If you have an active brain implant, please
contact the manufacturer of your implantable
device for information about the risk of
disturbance.
30
General warnings
X-ray, CT, MR, PET scanning, electrotherapy and surgery
·· Remove your hearing aid before X-ray,
CT/MR/PET scanning electrotherapy,
surgery etc. as your hearing aid may be
damaged when exposed to strong fields.
Heat and chemicals
·· The hearing aid must never be exposed to
extreme heat, for example, left inside a parked
car in the sun.
·· The hearing aid must not be dried in microwave
ovens or other ovens.
·· The chemicals in cosmetics, hairspray, perfume,
aftershave lotion, suntan lotion and insect
repellent can damage the hearing aid. Always

For information on whether your hearing aid is
a power instrument, please ask your hearing
care professional.
31
General warnings
Possible side effects
·· Hearing aids or domes may cause an
accelerated accumulation of ear wax.
·· The otherwise non-allergenic materials used in
hearing aids may in rare cases cause a skin
irritation or other side effects.
Please seek consultation with a physician
if these conditions occur.
Interference
·· The hearing aid has been thoroughly tested for
interference, according to the most stringent
international standards. However, interference
between the hearing aid and other devices
(e.g. some mobile telephones, citizens band
systems, shop alarm systems, and other
devices) may occur. If this occurs, increase the
distance between the hearing aid and the
interfering device.
32
General warnings
Connection to external equipment
·· The safety of the use of the hearing aid when
connected to external equipment (via auxiliary
input cable, via USB cable, or directly), is
determined by the external equipment. When
connected to external equipment plugged into
a wall outlet, this equipment must comply with
IEC-60065, IEC-60950 or equivalent safety
standards.
Safety information
·· Hearing aids should be adjusted by a hearing
care professional.
·· Never insert cleaning tools into the sound
outlet or microphone inlet. This could damage
the hearing aid.
·· Remove your hearing aid before sleeping.
·· Keep your hearing aid in the case for protection
when you are not wearing it.
·· Be aware of the possibility that the directional
microphone in your hearing aid may reduce the
volume of some warning sounds coming from
behind you.
33
Warning to hearing care
professionals
A hearing care professional should advise a
prospective hearing aid user to consult promptly
with a licensed physician (preferably an ear
specialist) before dispensing a hearing aid if the
hearing care professional determines 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
onset 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
accumulation or a foreign body in the ear
canal.
viii. Pain or discomfort in the ear.
34
Special care should be exercised in selecting and
fitting a hearing aid whose maximum sound
pressure level exceeds 132 decibels because
there may be risk of impairing the remaining
hearing of the hearing aid user. (This provision is
required only for those hearing aids with a
maximum sound pressure capability greater than
132 decibels [dB SPL].)
Important notice for prospective hearing aid 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 aid. Licensed physicians
who specialize in diseases of the ear are often
referred to as otolaryngologists, otologists or
otorhinolaryngologists. The purpose of medical
evaluation is to assure that all medically treatable
conditions that may affect hearing are identified
and treated before the hearing aid 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 aid. The physician will refer you to an
audiologist or a hearing care professional, as
appropriate, for a hearing aid evaluation.
35
The audiologist or hearing care professional will
conduct a hearing aid evaluation to assess your
ability to hear with and without a hearing aid.
The hearing aid evaluation will enable the
audiologist or hearing care professional to select
and fit a hearing aid to your individual needs. If
you have reservations about your ability to adapt
to amplification, you should inquire about the
availability of a trial-rental or purchase-option
program. Many hearing care professionals now
offer programs that permit you to wear a hearing
aid for a period of time for a nominal fee after
which you may decide if you want to purchase
the hearing aid. Federal law restricts this device
to sale by or on the order of a doctor, audiologist
or other hearing care practitioner licensed to
dispense hearing aids in your state-in accordance
with all applicable rules and regulations.
36
Children with hearing loss
In addition to seeing a physician for medical
evaluation, 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 and
educational and social growth of a child.
An audiologist is qualified by training and
experience to assist in the evaluation and
rehabilitation of a child with a hearing loss.
Federal law restricts this device to sale by or on
the order of a doctor, audiologist or other
hearing care practitioner licensed to dispense
hearing aids in your state-in accordance with all
applicable rules and regulations.
37
International warranty
Your hearing aid is covered by an international
limited warranty issued by the manufacturer for a
period of 12 months from the date of delivery.
This limited warranty covers manufacturing and
material defects in the hearing aid itself, but not
in accessories such as batteries, tubing,
speakers, earpieces and filters, etc. Problems
arising from improper/incorrect handling or care,
excessive use, accidents, repairs made by an
unauthorized party, exposure to corrosive
conditions, physical changes in your ear, damage
due to foreign objects entering the device or
incorrect adjustments are NOT covered by the
limited warranty and may void it.
The above warranty does not affect any legal
rights that you might have under applicable
national legislation governing sale of consumer
goods. Your hearing care professional may have
issued a warranty that goes beyond the clauses
of this limited warranty. Please consult him/her
for further information.
If you need service
Take your hearing aid to your hearing care
professional, who may be able to sort out minor
problems and adjustments immediately.

Mobile phone
Some hearing aid users have reported a buzzing
sound in their hearing aid when they are using
mobile phones, indicating that the mobile phone
and hearing aid may not be compatible.
The ANSI C63.19 standard determines the
prediction of compatibility between a specific
hearing aid and a mobile phone by adding the
numerical value of the rating for the hearing aid
immunity to the numerical value of the rating for
the mobile phone emissions.
A sum of 4 would indicate that the combination
of wireless device and hearing aid is usable; a
combined rating that equals 5 would provide
normal use; a combined rating of 6 or greater
would indicate excellent performance.
Whereas all hearing aids have acoustic coupling,
only the larger hearing aids have the physical
space for telecoil (inductive) coupling. These two
types of coupling have different rating scales
(M1 – M4 for acoustic coupling and T1 – T4 for
telecoil coupling, respectively) and both ratings
are therefore relevant when predicting the
compatibility of a particular hearing aid.
For a hearing aid with both acoustic coupling
and telecoil coupling with a rating of M4/T2 and
with a telephone rating of M3/T3, the combined
rating is 7 (M4 + M3) for the acoustic coupling
and 5 (T2 + T3) for the telecoil coupling.
40
According to the guideline given above, both
types of coupling will thereby be acceptable, with
the acoustic coupling indicating excellent
performance and the telecoil coupling indicating
normal use. The equipment performance
measurements, categories and system
­classifications are based upon the best
information available, but it cannot be guaranteed
that all users will be satisfied.
The immunity of this hearing aid is at least M2/T2.
The equipment performance measurements,
categories and system classifications are based
upon the best information available but cannot
guarantee that all users will be satisfied.
I M P O R TA N T N OT I C E
The performance of individual hearing aids may
vary with individual mobile phones. Therefore,
please try this hearing aid with your mobile
phone or, if you are purchasing a new phone,
be sure to try it with your hearing aid prior to
purchase. For additional guidance, please ask
your mobile phone provider for the booklet
entitled “Hearing Aid Compatibility with Digital
Wireless Cell Phones”.
41
Technical information
The hearing aid contains a radio transmitter
using short range magnetic induction technology
working at 3.84 MHz. The magnetic field strength
of the transmitter is very weak and is always
below –40 dBμA/m at 10 meter distance.
The emission power from the radio system is well
below international emission limits for human
exposure. For comparison, the radiation of the
hearing aid is lower than unintended
electromagnetic radiation from for example
halogen lamps, computer monitors, dishwashers,
etc.
The hearing aid complies with international
standards concerning radio transmitters,
electromagnetic compatibility and human
exposure.

Additional Information
Technical data measured with expansion, corresponding to
the test box measurement settings.
“2cc” refers to a coupler according to IEC 60318-5:2006.
Applied versions: ANSI S3.22-2014, IEC 60118-0:2015.
Full-on gain is measured with the gain control of the
hearing aid set to its full-on position minus 20 dB and with
an input SPL of 70 dB. This is to obtain a gain response
equal to the full-on gain response from e.g.
ANSI S3.22-2014, but without influence of feedback.
