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 aid you in better communication for many
years.

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 aids provide 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 them 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 your 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.

7 Getting started

Once you have placed the hearing aids on your ears, you can turn them on.

The hearing aid always starts in programme 1 and with the preset volume.

7.1 On/Off function

1. Close the battery door to turn on the hearing aid in programme
1 (one).

2. Open the battery door to turn off the hearing aid. Use your
fingernail to pull it open.

7.1.1 Power-on Delay

Power-on Delay delays the time before the hearing aid turns on after
you close the battery door. With Power-on Delay, you will hear a beep
( etc.) for each second of the delay period (5 or 10 seconds delay).

If you do not want to turn on the hearing aids prior to placing them on your ear, ask your hearing care
professional to deactivate Power-on Delay.

7.2 Inserting/Replacing the battery

1. Open the battery door completely by using your fingernail. Remove the used battery if present.

2. Prepare the new battery (please refer to page 2 for information on appropriate battery type/size
for your hearing aid). Remove the protective foil to activate the battery.

4. Insert the new battery with the positive side in
the correct position. Always insert the battery in
the door: never directly into the hearing aid.

5. Gently close the battery door.

i

1. Always use new Zinc-Air batteries that have a
minimum remaining shelf life of 1 year.

2. Whenever the hearing aids are not in use, remember to turn them off to avoid unnecessary
battery consumption.

3. At night, switch off the hearing aid and open the battery door completely to allow moisture
to evaporate and prolong the hearing aid’s lifespan.

4. If the hearing aid is experiencing frequent loss of connection to Interton wireless accessories,
contact your hearing care professional for a list of low impedance batteries.

i

WARNING: Batteries contain dangerous substances and should be disposed of carefully in the
interest of your safety and for the environment. Also, keep batteries away from pets, children and
mentally disabled persons.

7.3 Low battery indicator

When the batteries are low on power, your hearing aids reduce the volume, and play a melody every 15
minutes until they are empty and turn off.

i

NOTE: Keep spare batteries on hand.

7.3.1 Low battery indicator when paired with wireless accessories

The batteries drain faster when you use wireless functionalities like streaming from your smartphone
or from your TV via our TV Streamer 2.
As the battery power goes down, the wireless functions stop working. A short melody every five min­utes indicates that battery power is too low.

them.

7.4.1 Insert earmould

1. Hold the earmould between your thumb and index finger and position
its sound outlet in your ear canal.

2. Slide the earmould all the way into your ear with a gentle, twisting
movement.

3. Turn the top part of the earmould gently backwards and forwards so
that it tucks behind the fold of skin above your ear canal.

4. Move the earmould up and down and gently press to place it correctly
in the ear. Opening and closing your mouth can ease insertion.

5. Make sure the hearing aid sits firmly behind the ear.

By experimenting, you may discover an easier method. With proper insertion,
hearing aids should fit snugly but comfortably.

i

NOTE: It may be helpful to pull your ear up and outward with your op­posite hand during insertion.

i

CAUTION: Never attempt to modify the shape of the hearing aid, ear­moulds, or tubing yourself.

7.4.2 Remove earmould

1. Lift the hearing aid from behind the ear. For a moment, let it hang beside your ear.

2. Using your thumb and index finger, gently pull the earmould (not the hearing aid or the tubing)
loose from the ear.

3. Remove the earmould completely by gently twisting it.

18 19

7.4.3 Insert thin tube with dome

1. Hang the hearing aid over the top of the ear.

2. Hold the thin tube where it bends and gently place/push
the dome into the ear canal. Push the dome far enough
into the ear canal so that the thin tube lies flush with
the head (check with a mirror).

i

NOTE: To avoid whistling, it is important that the tube
and the dome fit correctly into your ear. For other possible reasons, check with the Troubleshoot­ing guide.

i

CAUTION: Never attempt to modify the shape of the hearing aid, earmoulds, or tubing yourself.

7.4.4 Remove thin tube with dome

1. Hold the thin tube with your thumb and forefinger and remove the tube.

2. For thin tube custom earmoulds, grasp the removal string and pull the earmould outward.

7.5 Operation of the hearing aid

7.5.1 Volume control

Your hearing aid has automatic volume control, which is individually set during the fitting session.

However, the volume control allows you to adjust the volume of
your hearing aids to your liking.

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

2. To decrease the volume, push 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 repeat 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.

i

NOTE: Your hearing care professional can disable the volume control or replace the volume
control with a non-functional cover.

20 21

7.5.2 Push button

Your hearing aid has a push 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 push 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 repeat 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.

8 Telephone use

Your hearing aid allows you to use the telephone as you normally do. However, finding the optimal posi­tion for your 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.

8.1 Using Interton Ready hearing aids with iPhone, iPad, and iPod touch (optional)

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 magnets

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

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

24 25

i

AutoPhone activation and good hearing on the telephone.

i

NOTE: If your hearing aids have enabled the Comfort Phone functionality, the hearing aid on 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 have 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.
NOTE: Your hearing care professional will gladly provide information regarding a teleloop system
at your home. Ask your hearing care professional for more information.

8.5.1 Teleloop systems

To use teleloop systems, follow these steps:

1. Switch your hearing aid to the Telecoil programme.

2. Find a good spot. Reception is not clear in all locations; it depends on the induction loop. Look
for signs or find another spot to sit.

3. If needed, adjust the volume.

4. When you leave, switch to a microphone programme.

26 27

8.5.2 HAC Telephone

The telecoil picks up the HAC telephone’s telecoil signal and converts it to sound.

To use the HAC telephone, follow these steps:

1. Switch your hearing aid to the Telecoil programme.

2. Pick up the telephone and place a call or answer a call.

3. Hold the telephone behind your ear – close to the hearing aid, and tilt it slightly outwards.

4. Listen to the dialling tone and move the telephone to get the best reception.

5. If needed, adjust the volume.

6. When you hang up, switch to a microphone programme.

i

NOTE: If the phone has a poor telecoil signal, use the microphone programme. To avoid whistling,
do not hold the handset too tightly against your ear.

Direct audio

8.6 Direct Audio Input (optional)

Your hearing aid is equipped with a Direct Audio Input facility. Direct Audio Input allows direct connec­tion of sound sources, a radio, television or even school equipment, to your hearing aid. Often, this will
improve the sound quality.

The sound source transmits to your hearing aid via a cable and a click-on device.

The hearing aid automatically detects the Direct Audio Input (DAI) source. The DAI supports wireless
systems as well.

Your hearing aid professional can adjust your hearing aids to fit the mix between the digital audio
input and the microphones on your hearing aids. You may, e.g. select to lower the ambient sounds and
amplify the sounds from the transmitter.

This accessory connects to the bottom of the hearing aids. Once clicked into place, the hearing aids
automatically close the microphones and switch to DAI.

28 29

8.6.1 Connecting DAI

9 Tinnitus Sound Generator (TSG) module

9.1 Intended use for the TSG module

Your Interton hearing aids includes the Tinnitus Sound Generator function, a tool for generating sounds
to be used in tinnitus management programmes to relieve suffering from tinnitus.

The Tinnitus Sound Generator 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 whistling.

9.2 User instructions for the TSG module

9.2.1 Description of the 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, crashing waves on a shore.

Modulation level and speed can also be configured to your likes and needs.

If you have two wireless hearing aids that support ear-to-ear synchronisation this functionality can be
enabled by your hearing care professional. This will cause the Tinnitus Sound Generator to synchronise
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 an optional 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 synchronisation is enabled your hearing care professional can also
enable environmental monitoring synchronisation so that the TSG noise level is automatically adjusted
simultaneously in both hearing aids dependent on the background sound level. Additionally if 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.

9.2.3 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.

32 33

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

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

9.4 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.

9.6 Prescription use of a Tinnitus Sound Generator (TSG) hearing aid

The TSG module should be used as prescribed by your doctor, audiologist or hearing care 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 the 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 disabled users
will require training by a doctor, audiologist, hearing care professional or the guardian for the insertion
and removal of the hearing aid containing the TSG module.

9.7 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.

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 counselling
and/or in a tinnitus management programme to relieve patients suffering from tinnitus.

11 How to apply domes

It is recommended that your hearing care professional shows you how to change the domes, because
incorrect dome replacement could result in the dome being left in the ear when you remove the hear­ing aid.

11.1 Open domes

Follow these steps to mount domes:

1. Push the new dome over the ribs flange on the thin tube.

2. Make sure that the new dome is properly and securely mounted.

11.2 Tulip domes

The Tulip domes are mounted in a similar manner to the ordinary domes, but a few extra steps are
required. The Tulip domes consist of two “petals”.
Follow these steps to mount domes:

1. Push the largest petal away from the thin tube using a finger. This bends the petal forward.

2. Push the new tulip dome over the flange.

3. Then push the largest petal backwards, and it will be placed on top of the smaller petal.

i

NOTE: It is important to note that the largest petal is the outermost petal.

4. Make sure that the new dome is properly and securely mounted.

12 Wireless accessories

With wireless accessories, you can stream sound from your TV or music player directly to your Interton
hearing aids and you can also control them without wearing an intermediary device around your neck.

TV Streamer 2 allows you to stream the audio from TV sets and virtually any other audio
source to your hearing aids at a volume level that suits you.

40 41

Remote Control 2 allows you to adjust the volume or mute your hearing aids, change programmes, and
see all your settings at a glance on its display.

Phone Clip 2 streams phone conversations and stereo sound directly to both hearing aids,
and it doubles as a simple remote control.

Micro Mic is a body worn microphone for your friend or colleague. It significantly improves
speech understanding in noisy situations.

Multi Mic works like the Micro Mic but doubles as a table microphone. Connects with loop and
FM systems, and has a mini-jack input for streaming audio from a computer or music player.

1. Consult a hearing care professional if you think there may be a foreign object in your ear canal,
if you experience skin irritation, or if excessive earwax accumulates with the use of the hearing
aid.

2. Different types of radiation, from e.g. NMR, MRI, or CT scanners, may damage hearing aids. It is
recommended not to wear hearing aids during these or other similar procedures. Other types
of radiation, such as burglar alarms, room surveillance systems, radio equipment, mobile tel­ephones, contain less energy and will not damage hearing aids. However, they have the potential
to momentarily affect the sound quality or temporarily create undesired sounds from hearing
aids.

3. Do not wear hearing aids in mines, oil fields, or other explosive areas unless those areas are
certified for hearing aid use.

4. Do not allow others to use your hearing aids.

5. Hearing aid usage by children or mentally disabled persons should be supervised at all times to
ensure their safety. The hearing aid contains small parts that could be swallowed by children.
Please be mindful not to leave children unsupervised with this hearing aid.

6. Hearing aids should be used only as prescribed by your hearing care professional. Incorrect use
may result in hearing loss.

7. Warning to hearing care professionals: Special care should be exercised in selecting and fitting
hearing aids with maximum sound pressure level that exceeds 132 dB SPL with an IEC 60711:1981
occluded ear simulator. The remaining hearing may risk further impairment.

8. Turn off your wireless functionality by using the flight mode in areas where radio frequency
emission is prohibited.

44 45

18 i Tinnitus Sound Generator (TSG) warnings

1. Sound generators can be dangerous if improperly used.

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

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

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

3. The volume control is an optional 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, if enabled, be configured to only provide a decrease of the
sound generator output level.

18.2 i TSG warning to hearing care professionals

A hearing care professional should advise a prospective sound generator user to consult promptly with
a licensed physician (preferably an ear specialist) before getting a sound generator 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 15dB at 500 hertz (Hz), 1000 Hz, and 2000
Hz.

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

8. Pain or discomfort in the ear.

i

CAUTION: The maximum output of the sound generator falls into the range that can cause hear­ing loss according to OSHA regulations. In accordance with NIOSH recommendations, the user
should not use the sound generator for more than eight (8) hours a day when set to a level of
85 dB SPL or above. When the sound generator is set to levels of 90 dB SPL or above, the user
should not use the sound generator for more than two (2) hours per day. In no case should the
sound generator be worn at uncomfortable levels.

50 51

19 i Battery warnings

Batteries contain dangerous substances and should be disposed of carefully in the interest of your
safety and for the environment. Please note:

1. To save battery power, turn off your hearing aids when they are not in use.

2. Keep batteries away from pets, children and mentally disabled persons.

3. DO NOT place batteries in your mouth. Consult a physician immediately if a battery has been
swallowed, as they can be harmful to your health.

4. Do not attempt to recharge batteries (Zinc Air) which are not specifically designated as re­chargeable because they may leak or explode.

5. DO NOT attempt to dispose of batteries by burning them.

6. Used batteries are harmful to the environment. Please dispose of them according to local regu­lations or return them to your hearing care professional.

7. Remove the batteries to prevent leakage when the hearing aids are not in use for an extended
period of time.

20 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 attain 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.

21 i Warning to hearing aid 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.

52 53

22 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.

23 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.
