Becoming Accustomed to Amplification
While purchasing a hearing system is a major step, it is only one step in a process toward more comfortable
hearing. Successfully adapting to the amplification your hearing system provides takes time and consistent
use.
You will enjoy more benefits from your Interton hearing system by taking the following actions:
• Wear the system regularly in order to get comfortable with using it.
• It takes time to get used to a hearing aid. It may help to begin by wearing your hearing aid for short
periods – even as little as 15 minutes – and then gradually building up your wearing time. In a way, it’s
no different than 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 the system, increase the wearing time and wear your hearing system
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. Fol-
lowing these suggestions will give your brain time to learn how to interpret amplification and increase the
benefits you get from using an Interton hearing system.

on just prior to placing them on your ear, your hearing care professional can activate a function called
Delayed on-activation. This function will delay the time in which the hearing instruments turn on by several
seconds after the battery compartment is closed. With Delayed on-activation, a beep will be heard for each
second of the delay period.
Inserting/Replacing the battery
1. Open the battery door completely by using your
fingernail.
2. Remove the used battery if present. Insert the new
battery with the positive side in the correct position.
3. Gently close the battery door.
iAlways use new Zinc-Air batteries that have a minimum remaining shelf-life
of 1 year.
Getting started
On&Off function
1. When the battery door is closed, the hearing
instrument turns on, and the default program will
be activated.
2. To turn off the hearing instrument, open
the battery door. Many individuals can use their
fingernail to pull it open.
iWhenever the hearing instruments are not in use, remember to turn them off
to avoid unnecessary battery consumption.

Low battery indicator
Your hearing care professional can set your hearing instrument to give an acoustical indication when the
battery is reaching its end of life. The hearing instrument will reduce amplification and emit a melody if bat-
tery power gets too low. This signal will recur every five minutes until the hearing instrument automatically
switches off. It is recommended that you keep spare batteries on hand.
Low battery indicator (instruments paired with accessories only)
Active usage of the Interton wireless accessories (Remote Control, Phone Clip and TV Streamer) requires
more battery power from the hearing instruments than when these are working on their own. When the
battery in the hearing instrument has depleted to a level at which use of the Interton TV Streamer TV and
Phone Clip cannot be supported, the hearing instrument will play two sets of descending tones. After
this, your hearing instrument and Interton Remote Control will continue to work as usual, but you will not
be able to use your Interton TV Streamer and Phone Clip. At some point the battery level will not support
the remote control either and you will once again hear the descending tones. The hearing instruments will
continue to work as usual. Once a new battery is inserted, full operation of the accessories will resume.
iWARNING
1. Remove the batteries to prevent leakage when the hearing instruments are not in use for an extended
period of time.
2. Do not attempt to recharge batteries (Zinc Air) which are not specifically designated as rechargeable
because they may leak or explode.
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. Keep batteries away from pets, children and individuals who are mentally challenged.
5. Do not attempt to dispose of batteries by burning them. Used batteries are harmful to the environment.
Please dispose of them according to local regulations or return them to your hearing care practitioner.

Telephone use
If your hearing instruments are fit with a receiver open dome or receiver tulip dome, you
can probably use the telephone as you normally would by holding it up to your ear canal
opening. If your hearing instruments are fit with a receiver power dome or RIE mould,
finding the optimal
position for holding a telephone while using a hearing instrument may require practice for
some individuals, and one or more of the following suggestions may be helpful.
1. Hold the telephone as you would normally.
2. Hold the telephone towards the top of the ear (closer to where the micro p hone s
are).
3. If whistling occurs, it may take a few seconds of holding the telephone in the same
position before the hearing instrument eliminates the feedback.
4. Any whistling may also be decreased by holding the telephone slightly away from
the ear.
5. Depending on your individual needs, your hearing care professional may activate a programme
specifically for telephone use.

26 27
Listen to radio or TV
When listening to the TV or the radio, start out by listening to news commentators since they usually speak
clearly, then try other programmes. If you find it difficult to listen to TV or radio, your hearing care profes-
sional will be able to give you advice on available accessories to enhance your listening capabilities for TV
and radio.
Cellular phones
Your hearing instrument is designed to comply with the most stringent Standards of International Electro-
magnetic Compatibility. However, not all cell phones are hearing instrument compatible. The varying de-
gree of disturbance can be due to the nature of your particular cellular phone or of your wireless telephone
service provider.
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 accessories to enhance listening capabilities.
AutoPhone (optional)
The AutoPhone function, allows your hearing instrument to automatically switch
to your telephone programme when a telephone receiver with an AutoPhone
magnet is raised to the ear. When the telephone receiver is removed from the
ear, the hearing instrument automatically returns to the previous listening pro-
gramme.
Placement of AutoPhone magnets
Place AutoPhone magnet on your telephone receiver to allow operation of the
AutoPhone function. In order to place AutoPhone magnet properly:
1. Clean the telephone receiver thoroughly.
2. Hold the telephone vertically, in a position similar to when making a telephone call.
3. Place the magnets just below the telephone receiver. Make sure not to cover
the microphone openings. If necessary, move the magnet to another position
to improve ease of use and comfort while speaking.
Scan a QR code with your
smart phone and watch a
instruction video.

28 29
4. If you are not satisfied with the strength of AutoPhone, you can reposition the AutoPhone magnet or add
additional AutoPhone magnets.
iOnly use a recommended cleaning agent to clean the telephone prior to placing the magnet on the
phone.
AutoPhone usage
Telephones can be used in a normal manner. A short melody will indicate that the AutoPhone feature has
automatically switched the hearing instrument to your telephone programme. Initially, you may need to
move the telephone receiver slightly to find the best position for reliable AutoPhone activation and good
hearing on the telephone. When remove you the telephone receiver AutoPhone will stay activated for a
few seconds to avoid accidental switching off. After that hearing instrument will switch to previously used
environmental programme.
iWARNING
AutoPhone warnings
1. Keep magnets out of reach of pets, children and mentally challenged persons. If a magnet is swallowed,
please seek advice from a medical practitioner.
2. The AutoPhone magnet may affect some medical devices or electronic systems. The
manufacturer of any magnetically sensitive devices (e.g. pacemakers) should advise
you regarding appropriate safety precautions when using your hearing instrument
and magnet in close proximity to the medical device or electronic system in question.
if the manufacturer cannot issue a statement, we recommend keeping the magnet or a telephone
equipped with the magnet 30 cm (12”) away from magnetically sensitive devices (e.g. pacemakers).

30 31
iCAUTION
AutoPhone precautions
1. High distortion during dialing or phoning may mean that the magnet is not in the optimal position relative
to the telephone receiver. To avoid the issue, please move the magnet to another place on the telephone
receiver.
2. Only use magnets supplied by Interton/GN Hearing.
Telecoil (optional)
If equipped, a telecoil can be activated by your hearing care professional and accessed through one of
the additional programmes. A telecoil picks up a telephone’s magnetic signal and converts it to sound. An
optional telephone programme may help to improve speech understanding on the telephone. When using
a telecoil programme, the receiver of the telephone may need to be held closer to the hearing instrument.
The handset of the telephone may need to be moved to slightly different positions in order to find the best
reception.
Tele-loop systems (optional)
Many places, such as theatres, houses of worship, and schools are equipped with tele-loop systems.
When using a telecoil programme with tele-loop systems, sound is picked up directly and may improve
speech understanding. If there is no sound from the hearing instruments in a tele-loop system and with a
telecoil programme activated, the tele-loop system may not be turned on or is not operating correctly. If
a facility is not equipped with a tele-loop system, sitting as close as possible to the front may be helpful.
