1 Introduction

Congratulations on the purchase of your new hearing aids. Interton’s innovative sound technology and
design, combined with the customized programming selected by your hearing care professional, will
make hearing a more enjoyable experience.

Please read this manual carefully in order to fully benefit from the use of your hearing aids. With
proper care, maintenance, and usage, your hearing aids will serve you in better communication for
many years.

This product is a custom-made device.

Ask your hearing care professional if you have any questions.

2 Intended use

Generic air-conduction hearing aids are wearable sound-amplifying devices intended to compensate
for impaired hearing. The fundamental operating principle of hearing aids is to receive, amplify, and
transfer sound to the eardrum of a hearing impaired person.

3 Becoming accustomed to amplification

While purchasing hearing aids is a major step, it is only one step in a process toward more comfortable
hearing. Successfully adapting to the amplification your hearing aid provides takes time and consistent
use.

You will enjoy more benefits from your Interton hearing aids by taking the following actions:

• Wear the hearing aids regularly in order to get comfortable with using them

• It takes time to get used to hearing aids. It may help to begin by wearing your hearing aid for
short periods – even as little as 15 minutes – and then gradually increasing your wearing time. In
a way, it is no different from adjusting to contact lenses. Speak to you hearing care professional,
who can design a schedule tailored just for you.

• As you get more comfortable with them, increase the wearing time and wear your hearing aids in
multiple types of listening environments.

It may take as long as several months for your brain to get used to all the “new” sounds around you.
Following these suggestions will give your brain time to learn how to interpret amplification and in­crease the benefits you get from using Interton hearing aids.

2. Pull outward while slightly rotating your hand forward.

7.5 Operation of the hearing aid

7.5.1 Volume control (optional)

Your hearing aid has automatic volume control, which is individually set during the fitting session.
However, the volume control (if present) allows you to adjust the volume of your hearing aids to your
liking.

1. To increase the volume, turn the
volume control up.

2. To decrease the volume, turn the
volume control down.

When you change the volume, the hearing
aid responds with a beep. When you reach
the upper or lower limits, the hearing aid
responds with a low-pitched beep.

i

NOTE: If you have two hearing aids with the Synchronised Volume Control function enabled,
volume control adjustments to one hearing aid automatically repeats in the second hearing aid.
When you change the volume on one of the hearing aids, it responds with one or more beeps. A
beep in the second aid follows.
NOTE: If your hearing aids support wireless Remote Control, you may use the Interton Remote
Control or the smartphone app to adjust e.g. the volume.

2322

7.5.2 Push button (optional)

Your hearing aid has a programme button allowing you to use up to four different listening pro­grammes. The list on page 2 tells which programs have been enabled.

1. Tap the programme button to switch between programmes.

2. You will then hear one or more beeps. The number of beeps indi­cates which programme you have selected (one beep = programme
one, two beeps = programme two, etc.).

3. When you turn the hearing aids off and then back on, they always
return to the default setting (programme one and preset volume).

i

NOTE: If you have two hearing aids with the Synchronised Push Button enabled, programme
changes to one hearing aid automatically repeats in the second hearing aid. When you change
a programme in one hearing aid, it responds with one or more beeps. The same number of con­firmation beeps in the second aid follow. This Synchronised Push Button can also be configured
to allow one side to control volume increase and the other side to control volume decrease. The
volume changes to one hearing aid are repeated on the other side to keep the levels the same.

8 Telephone use

Your hearing aid allows you to use the telephone as you ordinarily do. Finding the optimal position for
holding a telephone may require practice. One or more of the following suggestions may be helpful:

1. Hold the telephone up to your ear.

2. Hold the telephone towards the top of the ear (closer to where the
microphones are).

3. If whistling occurs, it may take a few seconds of holding the tel­ephone in the same position before the hearing aid eliminates the
feedback.

4. Whistling may stop by holding the telephone slightly away from the
ear.

i

NOTE: Depending on your individual needs, your hearing care professional may activate a pro­gramme specifically for telephone use.

8.3 Cellular phones

Your hearing aid complies with the most stringent Standards of International Electromagnetic Compat­ibility. However, not all cell phones are hearing aid compatible (HAC).

Any degree of disturbance can be due to the nature of your particular cellular phone or of your wireless
telephone service provider.

i

NOTE: If you find it difficult to obtain a good result while using your cellular phone, your hearing
care professional will be able to give you advice on available wireless accessories to enhance
listening capabilities.

8.4 AutoPhone

By placing a magnet on the telephone receiver, your hearing aids automatically switch the telephone
programme on when the receiver is close to your ear.

When you remove the receiver from your ear, the hearing aids automatically return to the previous
listening programme.

i

NOTE: Ask your hearing care professional to enable AutoPhone as one of your programmes.

8.4.1 Place the AutoPhone magnet

Follow these steps in order to place the AutoPhone magnet properly:

Clean the telephone thoroughly. Remove foil from magnet. Place the magnet.

the non-phone ear automatically turns down the volume.

8.5 Telecoil (optional)

Your hearing aid may be equipped with a telecoil. The Telecoil programme may help to improve speech
understanding with Hearing Aid Compatible telephones and in theatres, cinemas, houses of worship etc.
that has teleloop installed.

The telecoil cannot work without a teleloop (a.k.a. induction-loop) or a Hearing Aid Compatible (HAC)
telephone. When you switch on the Telecoil programme, your hearing aids pick up signals from the
teleloop or HAC telephone.

i

NOTE: If you are having trouble hearing with the teleloop, ask you hearing care professional to
adjust the programme.
NOTE: If there is no sound from the hearing aids in a teleloop system and an active Telecoil pro­gramme, the teleloop system may not be turned on or is not operating correctly.

2928

9 Tinnitus Sound Generator module

Your Interton hearing aid includes the Tinnitus Sound Generator (TSG) module, a tool for generating
sounds to be used in tinnitus management programmes to relieve suffering from tinnitus.
The TSG can generate sounds adjusted to the specific therapeutic needs and your personal preference
as determined by your doctor, audiologist, or hearing care professional.
Depending on the selected hearing aid programme and the environment you are in, you will sometimes
hear the therapeutic sound resembling a continuous or fluctuating noise.

9.1 Indication for use of the TSG module

The Tinnitus Sound Generator Module is a tool to generate sounds to be used in a Tinnitus Management
Program to relieve patients suffering from Tinnitus. The target population is primarily the adult popula­tion over 18 years of age. This product may also be used with children 5 years of age or older.

The Tinnitus Sound Generator module is targeted for healthcare professionals, which are treating
patients suffering from Tinnitus, as well as conventional hearing disorders. The fitting of the Tinnitus
Sound Generator module must be done by a hearing professional participating in a Tinnitus Manage­ment Program.

9.2 User instructions for the TSG module

9.2.1 Description of device

The Tinnitus Sound Generator (TSG) Module is a software tool that generates sounds to be used in tin­nitus management programmes to relieve suffering from tinnitus.

9.2.2 Explanation of how the device functions

The TSG module is a frequency and amplitude shaped white-noise generator. Noise signal level and fre­quency characteristics can be adjusted to the specific therapeutic needs as determined by your doctor,
audiologist or hearing care professional.

Your doctor, audiologist or hearing care professional can modulate the generated noise with the pur­pose of making it more pleasant. The noise can then resemble, for example, breaking waves on a shore.

9.2.3 The scientific concepts that form the basis for the device

The TSG module provides sound enrichment with the aim of surrounding the tinnitus sound with a neu­tral sound, which is easily ignored. Sound enrichment is an important component of most approaches
to tinnitus management, such as Tinnitus Retraining Therapy (TRT).

To assist habituation to tinnitus, this needs to be audible. The ideal level of the TSG module, therefore,
should be set so that it starts to blend with the tinnitus, and so that you can hear both your tinnitus as
well as the sound used.

In a majority of instances, the TSG module can also be set to mask the tinnitus sound, so to provide
temporary relief by introducing a more pleasant and controllable sound source.

9.2.4 TSG volume control

The sound generator is set to a specific loudness level by the hearing care professional. When switching
the sound generator on, the volume will have this optimal setting. Therefore, it might not be necessary
to control the volume (loudness) manually. However, the volume control provides the ability to adjust
the volume, or amount of stimulus, to the liking of the user.

3332

The volume control is an optional feature in the TSG module used for adjusting the sound generator
output level.

Modulation level and speed can also be configured to your likes and needs. An additional feature can
be enabled by your hearing care professional that allows you to select predefined sounds that simulate
sounds from nature, such as breaking waves or running water.

If you have two wireless hearing aids that support ear-to-ear synchronization, this functionality can be
enabled by your hearing care professional. This will cause the Tinnitus Sound Generator to synchronize
the sound in both hearing aids.

If your tinnitus troubles you only in quiet environments, your doctor, audiologist or hearing care profes­sional can set the TSG Module so that it becomes audible exclusively in such surroundings. The overall
sound level can be adjusted via a volume control. Your doctor, audiologist or hearing care professional
will review with you the need for having such a control.

For hearing aids where ear-to-ear synchronization is enabled your hearing care professional can also
enable environmental monitoring synchronization so that the TSG noise level is automatically adjusted
simultaneously in both hearing aids dependent on the background sound level. Additionally since the
hearing aid has a volume control then the background noise level monitored by the hearing aid and the
volume control can be used simultaneously to adjust the generated noise level in both hearing aids.

9.2.5 Using TSG with smartphone apps

The tinnitus sound generator control via hearing aid push buttons can be enhanced with wireless
control from a TSG control app on a smartphone or mobile device. This functionality is available in sup-

ported hearing aids when a hearing care professional has enabled the TSG functionality during fitting
of the hearing aid.

i

NOTE: To use smartphone apps, the hearing aid must be connected with the smartphone or
mobile device.

The purpose of medical evaluation is to assure that all medically treatable conditions that may affect
tinnitus are identified and treated before the sound generator instrument is used.

The sound generator instrument is a tool to generate sounds to be used with appropriate counseling
and/or in a tinnitus management programme to relieve patients suffering from tinnitus.

9.4 i Tinnitus Sound Generator warnings

1. Sound generators should be used only as advised by your doctor, audiologist, or hearing care
professional.

2. Sound generators are not toys and should be kept out of reach of anyone who might cause
themselves injury (especially children and pets).

3. Sound generators can be dangerous if improperly used.

9.4.1 i Tinnitus Sound Generator precautions

1. Should the user develop any side effects from using the sound generator, such as dizziness,
nausea, headaches, perceived decrease in auditory function or increase in tinnitus perception,
the user should discontinue use of the sound generator and seek medical evaluation.

2. The volume control is a feature in the TSG module used for adjusting the sound generator
output level. To prevent unintended usage by paediatric or physically or mentally disabled us­ers, the volume control must be configured to only provide a decrease of the sound generator
output level.

3. Children and physically or mentally disabled users will require guardian supervision while wear­ing the TSG hearing aid.

9.3.3 i Prescription use of a Tinnitus Sound Generator hearing aid

The TSG module should be used as prescribed by your doctor, audiologist or hearing healthcare profes­sional. In order to avoid permanent hearing damages, the maximum daily usage depends on the level of
the generated sound.

Should you develop any side effects from using the sound generator, such as dizziness, nausea, head­aches, perceived decrease in auditory function or increase in tinnitus perception, you should discon­tinue use of sound generator and seek medical evaluation.

The target population is primarily the adult population over 18 years of age. This product may also be
used with children 5 years of age or older. However, children and physically or mentally challenged us­ers will require training by a doctor, audiologist, hearing healthcare professional or the guardian for the
insertion and removal of the hearing instrument containing the TSG module.

9.3.4 Important notice for prospective sound generator users

A tinnitus masker is an electronic device intended to generate noise of sufficient intensity and band­width to mask internal noises. It is also used as an aid in hearing external noises and speech.

Good health practice requires that a person with a tinnitus condition have a medical evaluation by a
licensed physician (preferably a physician who specializes in diseases of the ear) before using a sound
generator. Licensed physicians who specialize in diseases of the ear are often referred to as otolaryn­gologists, otologists or otorhinolaryngologists.

4746

16 i Hearing aid expectations

A hearing aid will not restore normal hearing and will not prevent or improve a hearing impairment
resulting from organic conditions. Consistent use of the hearing aid is recommended. In most cases,
infrequent use does not permit you to obtain full benefit from it.

The use of a hearing aid is only part of hearing rehabilitation and may need to be supplemented by
auditory training and instructions in lip-reading.

17 i Warning to hearing aid hearing care professionals (US Only)

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:

1. Visible congenital or traumatic deformity of the ear.

2. History of active drainage from the ear within the previous 90 days.

3. History of sudden or rapidly progressive hearing loss within the previous 90 days.

4. Acute or chronic dizziness.

5. Unilateral hearing loss of sudden or recent onset within the previous 90 days.

6. Audiometric air-bone gap equal to or greater than 15 decibels at 500 hertz (Hz), 1,000 Hz, and
2,000 Hz.

7. Visible evidence of significant cerumen accumulation or a foreign body in the ear canal.

8. Pain or discomfort in the ear.

USED BATTERIES ARE HARMFUL TO THE ENVIRONMENT. PLEASE DISPOSE OF THEM ACCORD-

ING TO LOCAL REGULATIONS OR RETURN THEM TO YOUR HEARING CARE PROFESSIONAL.

IF THE BATTERIES ARE NOT INSERTED CORRECTLY, THE DEVICE WILL NOT WORK AND THE

BATTERIES MAY BUILD UP HEAT. IF THIS HAPPENS, PLEASE REMOVE THE BATTERIES.

4948

19 i Children with hearing loss (US Only)

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.

18 i Important notice for prospective hearing aid users (US Only)

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. 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 programme. Many hearing care professionals now offer
programmes 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.
