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.

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.
Delayed activation
Hearing instruments can be turned on once you have placed them on your ears. If you prefer to turn them
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
On
Off
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.

16 17
Low battery indicator
Your hearing care professional can set your hearing instrument to give an acoustical indication when the bat-
tery is reaching its end of life. The hearing instrument will reduce amplification and emit a melody if battery
power gets too low. This signal will recur every five minutes (15 minutes for GAN390-DVI and GAN290-DVI) un-
til 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.

18 19
Inserting/Removing hearing instruments
Insertion (custom earmoulds)
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 ensure it is positioned correctly in the ear. Opening
and closing your mouth can ease insertion.
5. Make sure the hearing instrument is seated behind the ear.
By experimenting, an easier method may be discovered. With proper insertion, hearing
instruments should fit snugly but comfortably. If the hearing instruments cause irritation
of the ears, contact your hearing care professional.
iCAUTION
Never attempt to modify the shape of the hearing instrument, earmoulds, or tubing your-
self.
iIt may be helpful to pull your ear up and outward with your opposite hand during
insertion.

20 21
Insertion (domes/custom earmoulds with thin tubes)
1. Hold the thin tube where it bends, and gently 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.
2. It is important that the tube and the dome fit correctly into your ear.
3. When the dome is place correctly, you should not be able to see the thin tube sticking out when facing
a mirror.
iCAUTION
You should never attempt to bend or modify the shape
of the thin tube.
iCAUTION
Use only original Interton/GN Hearing consumables
e.g. tubes and domes.
Removal (custom earmolds)
1. Hold a portion of your earmould towards the back of the ear.
2. Pull the earmould outward and simultaneously rotate the earmould forward.
3. Consult your hearing care professional if you have difficulties removing the hearing instrument.
Removal (domes/custom earmoulds with thin tubes)

Operation of the hearing instrument
Volume control (optional)
The volume control will allow the volume of hearing instruments to be in-
creased or decreased.
1. To increase the volume, push the volume control up or move the wheel
upwards.
2. To decrease the volume, push the volume control down or move the
wheel downwards.
When volume is increased or decreased, a beep signal will be heard for each incremental
change. When the upper or lower limits of the volume range are reached, a beep signal with a longer dura-
tion will be heard. During the fitting of the instrument, your hearing care professional will have chosen an
optimal volume setting for you. When switching the instrument on, the volume will have this optimal setting.
Push button
Depending on your experience level with hearing in-
struments, individual hearing needs, and the type of
listening environments you experience, your hearing
care professional may activate additional programmes.
If additional programmes have been activated, the fol-
lowing list explains how they work.
1. You can switch between programmes by pushing
the push button once.
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 the hearing instruments are turned off and then back on, the hearing instrument always returns
to the default setting (programme one).

24 25
Only applicable to wireless devices.
If your hearing system supports wireless functionality and it is paired with wireless accessory like TV
Streamer you can activate streaming mode.
1. Push and hold the push button for 2 seconds.
2. You will then hear short melody that indicates streaming mode.
To switch back to environmental program push the push button shortly. Hearing Instrument will return to

Telephone use
Finding the optimal position for holding a telephone 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 microphones
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 ea r.
5. Depending on your individual needs, your hearing care professional may activate
a programme specifically for telephone use.
For Step devices:
It is possible to disable wireless operation by opening and closing the battery compartment three times
within a ten second period (open-close, open-close, open-close). Your instruments will now be in flight
mode.
If the hearing instrument is in flight mode, the hearing instrument must have been operating in flight mode
for at least 10 seconds before attempting to enable wireless again. it is possible to re-enable wireless
operation by opening and closing the battery door once. 10 seconds after this operation is completed,
wireless operation will begin again.
iIt is important to wait an additional 15 seconds after wireless function resumes before opening and
closing the battery compartment again for any reason. If the battery compartment is opened and closed
during this 15 second window, flight mode will resume.

28 29
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 pro-
gramme 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
programme.

30 31
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.
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 you remove 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.

32 33
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).
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.

34 35
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.
Direct Audio Input (optional)
Use of Direct Audio Input (DAI), which enables a direct connection of the hearing instruments to items such
as television, radio, and remote microphones, may increase speech understanding for some individuals.
The sound source is connected to the hearing instruments by a cable or a wireless FM system to the audio
boot. This accessory connects to the bottom of the hearing instruments, and once properly clicked into
place, the hearing instruments switch to DAI automatically.
Connecting/Disconnecting audio boots

grease or moisture. Do not use water or solvents, as these can damage the hearing instrument(s).
2. Never immerse hearing instruments in water or other liquids, as liquids may cause permanent damage
to the hearing instruments.
3. Avoid rough handling of hearing instruments or dropping them on hard surfaces or floors.
4. Do not leave hearing instruments in or near direct heat or sunlight, such as in a hot, parked car, as
excessive heat can cause damage or deform the casing.
5. Do not wear your instrument while showering, swimming, in heavy rain or in a moist atmosphere such
as a steam bath or sauna.
6. If your instrument does get wet, or if it has been exposed to high humidity or perspiration, it should be
left to dry out overnight with the battery out and the battery compartment open. It is also a good idea to
put the instrument and battery in a sealed container together with a drying agent (desiccator) overnight.
Do not use the instrument until it is completely dry. Consult your hearing care professional as to which
drying agent to use.
7. Remove your hearing instrument when applying such things as cosmetics, perfume, aftershave, hair
spray, and suntan lotion. These might get into the instrument and cause damage.

Cleaning earmoulds
1. Remove the earmould and attached tubing from the hearing instruments prior to
cleaning.
2. Clean the earmould using a mild soap, and rinse with lukewarm water.
3. After cleaning, dry earmoulds thoroughly and remove any residual water and debris
from the tubing utilising an air bulb and wire loop.
iEarmould tubing may become stiff, brittle, or discoloured over time. Contact your
hearing care professional regarding tube changes.
Cleaning thin tubes and domes
1. Remove thin tubes from hearing instruments before cleaning by unscrewing
them counter clockwise.
2. Wipe down thin tubes and domes with a damp cloth.
3. In order to clear the thin tube of moisture and debris, push the black cleaning
rod through the thin tube, beginning at the end opposite the dome.
iThin tube and dome systems should be changed every three months or
sooner, should the components become stiff or brittle.
