NOTE
In addition to these user instructions, a separate user manual is
provided describing the various ear-set solutions available for
your hearing aid: “Ear-sets for Widex BTE hearing aids”.
WARNING
This booklet and the manual “Ear-sets for Widex BTE hearing
aids” contain important information and instructions. Read
these booklets carefully before you start using the hearing aid.
NOTE
Your hearing aid, ear-set and accessories may not look exactly
as illustrated in this booklet. We also reserve the right to make
any changes considered necessary.
Intended use
The SUPER™ hearing aids are intended as air conduction amplification devices to be used in everyday
listening environments. The SUPER hearing aids may
be provided with the Zen program intended to provide
a relaxing sound background (i.e. music/noise source)
for adults who desire to listen to such a background in
quiet.
Indications for use
The devices are indicated for individuals with a range
of hearing loss severity from moderate (40 dB HL) to
severe-to-profound (120 dB HL) and all hearing loss
configurations.
6
They are to be programmed by licensed hearing care
professionals (audiologists, hearing aid specialists, otolaryngologists) who are trained in hearing (re)habilitation as well as tinnitus management.
Description of device
Your SUPER™ hearing aid is used with an ear-set which
consists of an earwire and an ear-tip or earmold, in
which the receiver is placed. The hearing aid uses a proprietary wireless technology, the WidexLink, to enable
communication between the left and the right hearing
aids, as well as between the hearing aids and the DEX
accessories. Your hearing aid is to be powered by a 675
type battery.
Your hearing aid may be provided with an optional listening program called Zen. It makes musical tones (and
sometimes a rushing noise) in the background. These
sounds are shaped according to your hearing loss.
WARNING
With a custom earmold, this hearing aid is capable of producing a sound pressure level exceeding 132 dB SPL.
There may be a risk of damaging your residual hearing.
7
Right/left identification
The arrow shows the position of the
identification mark (red mark = right
and blue mark = left).
Acoustic indicators
The hearing aid may be set to produce a signal to indicate the use of certain functions. The signal may be a
spoken message or tones adjusted by the hearing care
professional in consultation with you. The signal can
also be deactivated.

The battery
We recommend zinc-air batteries. Use a size 675 battery for the hearing aid.
To obtain replacement batteries, please consult your
hearing care professional. It is important to take note
of the expiration date and the recommendations on the
battery pack regarding disposal of used batteries.
Inserting the battery
Before inserting a new battery into the
hearing aid, remember to remove the adhesive tab. Once the tab has been removed,
the battery will start functioning after a few
seconds.
CAUTION
Do not use batteries if there is a sticky residue from the tab or
other unwanted substance, as this can cause the hearing aid to
malfunction.
Use the nail grip to gently swing the battery drawer completely open. Do not
press the drawer beyond the open position.
9
Place the battery in the drawer, so that the plus (+) sign
on the battery faces upward. You can use the battery
magnet provided to steer the battery into place.
If the battery drawer does not close easily, the battery
is incorrectly inserted.
When changing battery, it is a good idea to hold the
hearing aid over a table.
The hearing aid may be provided with
a battery drawer without a nail grip,
which means that you need a tool to
open the battery drawer. This type
of drawer can be a good choice if the
hearing aid is worn by a child. A special
tool for opening the drawer will be included with this drawer.
10
The battery drawer is opened as illustrated.
Low battery indication
An acoustic indicator will sound when the battery is
nearly exhausted, unless this function has been disabled (see page 8). We recommend that you always
have a spare battery with you.
WARNING
Never leave an exhausted battery in the hearing aid. Exhausted
batteries may leak, damaging the hearing aid.
WARNING
Your hearing aid may stop functioning, for instance if the battery is exhausted. You should be aware of this possibility, in particular when you are in traffic or are otherwise dependent on
warning signals.
11
Turning the hearing aid on and off
The battery drawer of the hearing aid also functions as
the on/off switch.
Close the battery drawer completely to
turn on the hearing aid. An acoustic indicator will indicate that the hearing aid
has been switched on, unless this function has been disabled.
To turn off the hearing aid, open the battery drawer slightly to the first position
where a click is felt.
Please remember to turn off the hearing aid when it is
not in use. Remove the battery if the hearing aid will
not be used for several days.
12
Positioning the hearing aid in the ear
Hold the earmold with your thumb and forefinger and
slowly guide it into your ear canal until you feel resistance. Let go of the earmold and use the tip of your forefinger to gently push it into your ear until it rests comfortably in your ear canal.
To help position the earmold properly you could pull
the outer ear backwards and upwards with the opposite hand.
Place the hearing aid behind the ear, so that the earwire
rests comfortably on the ear, close to your head.
The illustrations show an earmold. For further information on ear-tip/earmold types and procedures, see the
separate ear-set user manual provided.
13
Removing the hearing aid
Remove the hearing aid from its position behind the
ear.
Hold the earmold with your thumb and forefinger and
pull gently.
WARNING
Do not pull the earwire to remove the earmold, as this may
damage the earwire.
If it is difficult, you can try to move the earmold carefully from side to side. It may also help to pull the outer ear backwards and upwards with the opposite hand.
14
Volume adjustment
The hearing aid volume is adjusted automatically in accordance with your sound environment.
Your hearing aid is provided with a volume control,
shaped like a small lever (unless your hearing care professional has removed it for you).
Push the lever upwards to gradually
raise the volume.
Push the lever downwards to gradually lower the volume.
In the default setting, any volume adjustment will affect both hearing aids.
To alter the increments in which the volume is increased
or decreased, consult your hearing care professional.
Each time you operate the volume control, you will
hear a beep-tone, unless this function has been disabled. When the maximum or minimum adjustment level is reached, a steady tone will sound.

18
If your needs change over time, the combination of listening programs can be altered.
CAUTION
When selecting Phone+ as listening program, please remember
that there are situations in which it is particularly important to
be able to hear the surrounding sounds.
Zen program
Your hearing aid may be provided with a unique optional listening program called Zen. It makes musical tones
(and sometimes a rushing noise) in the background using the latest in fractal technology. These sounds are
shaped according to your hearing loss so you can listen to them at any time and at any place with a simple
push of the program button. The Zen program may be
used alone (without amplification) in quiet when you
are not required to hear surrounding sounds. Or, it may
be used with another program so both the surrounding
sounds and the generated sounds (fractal tones and
noise) are heard together.
The duration of the Zen play time can be set by your
hearing care professional according to your needs.
19
Benefits
The Zen program may provide a relaxing listening
background for some people. When the Zen program
is used in a tinnitus management program, its wearer
may experience some relief from tinnitus.
Indications for use
The Zen program is intended to provide a relaxing
sound background (i.e., music/noise source) for adults
who desire to listen to such a background in quiet. It
may be used as a sound therapy tool in a tinnitus treatment program that is prescribed by a hearing care professional (audiologists, hearing aid specialists, otolaryngologists) who is trained in tinnitus management.
Directions for use
The Zen program can be activated with a simple push
of the program button on the hearing aid (or on the
remote control). Depending on how your hearing care
professional has set up the program, you can access
the Zen program by a “short-press” of the program
button or a “long-press” of the program button.
• “Short-press” option – the program button is pressed
for less than a second. At most two listening programs can be programmed for Zen.
20
• “Long-press” option – the program button is pressed
and held for more than 1 second. Up to three Zen
styles are available. A “short-press” of the program
button in the long-press mode will allow you to cycle through the available Zen styles. You can exit the
“long-press” mode by pressing and holding the program button for more than a second.
Because of the unique ways in which Zen is programmed in your hearing aid, please follow the recommendations of your hearing care professionals as to
how to use the program, when to use the program and/
or how long to use the program.
Precautions
To ensure the safety and effectiveness of the Zen program when used as a sound therapy tool for tinnitus,
the tinnitus management program must be designed
and conducted by hearing care professionals who are
trained in tinnitus management. A tinnitus management program should include a complete audiological
evaluation, tinnitus diagnosis, counseling, use of proper amplification and/or sound therapy tools.
Prior to any tinnitus management program, it is advisable that you seek medical attention to exhaust any
medical or surgical treatment options.
21
Use your hearing aid and the Zen program according
to the directions and schedule recommended by your
hearing care professionals.
Risks
There are no known risks or side effects associated with
the use of the Zen program. However, consistent with
our recommendations on the use of conventional hearing aids, stop using the hearing aids (and the Zen program) and seek attention from your hearing care professional if any of the following symptoms are noted:
• Skin irritation
• Perceived decrease in loudness, tolerance of sounds,
speech not as clear, or worsening tinnitus
CAUTION
Use of the different Zen programs may interfere with hearing
surrounding sounds including speech. The programs should not
be used when hearing such sounds is important. Switch the
hearing aid to a non-Zen program in those situations.
CAUTION
If you perceive decrease in loudness, tolerance of sounds,
speech not as clear, or worsening tinnitus, contact your hearing
care professional.

CARING FOR YOUR HEARING AID
The hearing aid is a valuable object and should be
treated with care. Here are some things you can do to
prolong the life of your hearing aid:
CAUTION
• Turn off your hearing aid when it is not in use. Remove the
battery if the hearing aid will not be used for several days.
• When the hearing aid is not in use, keep it in its case in a dry
location out of reach of children and pets.
• Do not expose the hearing aid to extreme temperatures or
high humidity. Make sure to dry the hearing aid thoroughly after heavy perspiration such as that which may occur during intense physical activity, e.g. playing sports.
• Avoid dropping your hearing aid – perform cleaning and battery changes while holding the hearing aid above a soft surface.
• Do not wear your hearing aid while in the shower or swimming,
or when using a hair dryer, perfume, hair and body sprays or
gels such as suntanning lotions or creams.
• In environments with high humidity, a drying kit may be used
daily to reduce the amount of moisture inside the hearing aid.
See the instructions enclosed with the drying kit.
31
WARNINGS
WARNING
Hearing aids and batteries can be dangerous if swallowed or
used improperly. Swallowing or improper use can result in
severe injury or even fatalities. In case of ingestion, contact a
physician immediately and the 24 Hour National Button Battery Ingestion Hotline at (202) 625-3333.
• Keep hearing aids and their parts, accessories and batteries out
of reach of children and anyone else who might swallow such
items or otherwise cause injury to themselves. Do not change
batteries in front of them and do not let them see where you
keep your battery supply. Discard used batteries carefully.
• Batteries are very small and can easily be mistaken for pills or
the like. Never put a battery or hearing aid in your mouth for
any reason as you may risk swallowing it.
32
WARNING
• Risk of explosion if battery is replaced by an incorrect type or
recharged. Dispose of used batteries according to the instructions on the battery pack.
• Never allow others to wear your hearing aid, as this could cause
permanent damage to their hearing.
• When selecting a listening program, please remember that there
are situations in which it is particularly important to be able to
hear the surrounding sounds (e.g. traffic, warning signals).
• The hearing aid is made of modern non-allergenic materials.
Nonetheless, in rare cases skin irritation may occur. If you notice skin irritation in or around your ear or ear canal, contact
your hearing care professional.
• Please note that when using any type of hearing aid, you must
allow regular ventilation of the ear. If the ear is not adequately ventilated, there may be a slightly increased risk of infection
or disease in the ear canal. We therefore recommend that you
remove the hearing aid and ear-set from your ear when you go
to bed, to allow the ear canal to be ventilated. If possible, you
should also remove your hearing aid and ear-set during the day
if there are any periods when you do not need them. Make sure
that you clean and inspect your hearing aid and ear-set as required. If an ear infection or disease occurs, you should seek
medical attention and contact your hearing care professional for advice on how to disinfect the various hearing aid parts.
Do not under any circumstances use alcohol, chlorine or similar
substances for this purpose.
• Regular use of a de-humidifier is recommended to help avoid
malfunction of the hearing aid.
• Do not use Widex hearing aids in mines or other areas with explosive gases.
33
WARNING
• Do not wear your hearing aid during radiation, X-rays, MRIs,
CT or other medical treatments and scans. The emissions
from these procedures as well as from other types of radiation,
such as that in a microwave oven, can damage your hearing
aid. Radiation from, for example, room surveillance equipment,
burglar alarms and cell phones is weaker and will not damage
the hearing aid but may create audible interference.
CAUTION
• Your hearing aid has been tested for interference according
to international standards. Nevertheless, it is possible that unforeseen interference may occur in the hearing aid due to electromagnetic radiation from other products such as alarm systems, room surveillance equipment and cell phones.
• Although your hearing aid has been designed to comply with
the most stringent international electromagnetic compatibility
standards, the possibility cannot be excluded that it may cause
interference with other equipment, such as medical devices.
• Never try to open or repair the hearing aid yourself.
34
ADVICE
NOTE
• The hearing aid will not restore normal hearing and will not prevent or improve a hearing loss resulting from organic conditions. However, the hearing aid can help you to make the best
possible use of your remaining hearing ability. You should also
bear in mind that it can take time to get used to a new hearing
aid and new sounds.
• In most cases, using the hearing aid infrequently will not permit
you to gain full benefit from it.
• The use of a hearing aid is only part of hearing habilitation and
may need to be supplemented by auditory training and instruction in lipreading.
• The use of hearing aids increases the risk of accumulation of
earwax. Contact your physician/ENT doctor if you suspect that
a plug of earwax has accumulated in your ear. Earwax may not
only reduce your own hearing but also the effect of the hearing
aid considerably. It is a good idea to ask your physician to clean
your ears a couple of times a year.

(Benefits) The use of wireless transmission allows convenient
and synchronized control of hearing aid functions. The SUPER
wireless hearing aids share input information between the two
partner hearing aids. In so doing, the wearers would experience
the following additional user benefits (only when wearing binaural
SUPER hearing aids).
Synchronization of volume control settings between hearing
aids – The volume in both hearing aids will change when the VC is
adjusted on one ear.
Synchronization of listening programs between hearing aids – The
same listening program is used in both hearing aids when one is
changed by the user.
Surveillance of partner hearing aid – The hearing aid(s) will signal
an alert (“partner check”) when a hearing aid battery has expired,
or that one of the hearing aids has fallen off. In rare instances, a
much stronger wireless source nearby may activate this alert. This
serves as an early warning to the wearer of such service interruption.
Coordination of compression – The SUPER hearing aids maintain
the intensity level difference between ears (inter-aural level difference, ILD). In some situations where speech is presented to
one side and noise the other side, this coordinated action could
enhance the relative loudness of the speech sounds to the noise
background and improve speech understanding for some wearers.
More accurate identification of feedback – The SUPER hearing aids
distinguish between “true” hearing aid whistling (or feedback) and
music sounds to prevent unnecessary feedback cancellation and
preserve natural sound quality.
38
(Contraindications):
• Congenital or traumatic deformity of the ear
• Active drainage from the ear within 90 days
• History of rapid progressive hearing loss within previous 90
days
• Acute or chronic dizziness
• Sudden unilateral hearing loss in previous 90 days
CAUTION
(Risks) The use of the SUPER/DEX should not interfere with
other devices such as a pacemaker. However, to be extra cautious, Widex follows the guidelines recommended by the manufacturers of implantable defibrillators and pacemakers for their
patients when using cell phones. Specifically, hearing aid wearers who also use a pacemaker should
• Keep the hearing aids at a distance of at least 15 cm/6 inches
away from the pacemaker and
• Do not carry the hearing aids (and/or any of the DEX accessories) in a shirt pocket or close to the chest.
• If any interference is observed, do not use the hearing aids
(and/or DEX) and contact your pacemaker manufacturer and
hearing healthcare professional immediately.
39
RADIO TRANSMITTER / CABLES / TRANSDUCERS
The SUPER™ series hearing aid contains a radio transmitter /
receiver with the following
Radio transmitter parameters:
• Frequency (range): 10.6 MHz (10.2 – 11.0 MHz)
• Bandwidth (-15dB): 660 kHz
• Channel: Single channel radio
• Modulation: FSK
• Radiated output power: 29 pW / -75 dBm
• Magnetic field strength: -54 dBμA/m @ 10 m
• Duty Cycle: < 5 % (averaged over 1 hour of operation)
• Simplex or semi duplex capability
The radio receiver in the SUPER™ series hearing aid is using the
same frequency and bandwidth as the transmitter.
Cables and transducers:
No cables and transducers are used neither during normal use of
the SUPER™ series hearing aid nor during programming of the
hearing aid.

QUALITY OF SERVICE FOR WIRELESS TECHNOLOGY IN
THE WIDEXLINK SYSTEM
WidexLink wireless technology enables communication between
two partners of a binaural pair of SUPER hearing aids and with
their matched external devices. The requirements for the quality
of service (QoS) vary among the various components and their
intended user scenarios.
For programming, these requirements include a BER (Bit Error
Rate) better than 10-3, at a bitrate of 212 kbits/s, a semi-duplex
transmission with a required acknowledge, a transmission latency
in each direction (2x) and a receive-to-transmit mode (RX to TX)
time. The data are saved in the hearing aid even when transmission
is interrupted.
During daily use, the requirements on audio streaming between
hearing aids include a BER better than 10-3. The communication is
simplex with a bitrate of 212 kbits/s. The additional audio decoding in this mode results in a longer latency which is less than 10 ms.
For remote control commands the QoS requirements include a
BER better than 10-2. The lower BER requirement results from redundant transmissions. Each key press results in transmissions of
7 data packages of which only one is needed for a successful communication.
For inter-ear communication between hearing aids, a BER better
than 10-3 is required. The communication is updated every 50 ms
(or 20 Hz). The hearing aids continue to amplify based on the last
saved settings even when the transmission range is exceeded or
when communication is interfered.
41
Wireless Security Measures
Security of the wireless signals is assured through device system
design that includes:
• Individual MAC address for each unit which is checked during
each transmission.
• A built-in pairing table which specifies valid and legitimate
pairing among units
• A proprietary Widex communication protocol which checks the
package numbers during each transmission.
• A Cyclic Redundancy Check (CRC) to check data validity and
correct errors.

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 aid dispenser, as appropriate, for a hearing aid evaluation.
The audiologist or hearing aid dispenser 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
dispenser 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 aid dispensers 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 the sale of hearing aids 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.
51
Children with hearing loss
In addition to seeing a physician for a 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 the 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.
