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 of your hearing aids takes
time and consistent use.
You will enjoy more benefits from your Interton hearing aids by taking the following ac-
tions:
• Wear the hearing aids regularly in order to get comfortable with using them
• It takes time to get used to hearing aids. Ask your hearing care professional to design a
schedule tailored just for you
• As you get more comfortable with your hearing aids, increase the wearing time and
wear them in multiple types of listening situations
It may take as long as several months for your brain to get used to all the “new” sounds
around you. Following the above suggestions will give your brain time to learn how to in-
terpret amplification and increase the benefits you get from using Interton hearing aids.

Getting started
On/Off function
1. When the battery door is closed, the hearing aid turns on, and
the default program will be activated.
2. To turn off the hearing aid, open the battery door. Many indi-
viduals can use their fingernail to pull it open.
i Tip: Whenever the hearing aids are not in use,
remember to turn them off to avoid unnecessary bat-
tery consumption.
Power-on Delay
Hearing aids 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 Power-on Delay.
This function will delay the time in which the hearing aids turn on by ten seconds after the
battery compartment is closed. This reduces the risk that the hearing aids will whistle while
you put them on. With Power-on Delay, a beep will be heard for each second of the delay
period.

Battery door lock
Your hearing care professional can install a Left/Right side indicator
(Blue=Left, Red=Right), which can be used to lock the battery door. Once
locked, the hearing aid can only be turned off once the hearing aid
is unlocked.
To lock the battery door:
1. Close the battery door
2. Using the battery door locking tool, slide the color marker to the
right.
To unlock the battery door: Slide the color marker to the left.
Unlock Lock
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. The battery door has a ‘+’ indicator to help determine the correct
insertion.
3. Always use new Zinc-Air batteries that have a minimum remaining shelf life of 1 year.
4. Gently close the battery door.
i Note: To save battery power, turn off your hearing aids when they are not in use.

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 posi-
tioned correctly in the ear. Opening and closing your mouth can ease
insertion.
5. Make sure the hearing aid is seated behind the ear.
By experimenting, an easier method may be discovered. With proper inser-
tion, hearing aids should fit snugly but comfortably. If hearing aids cause
irritation of the ears, contact your hearing care professional. Never attempt
to modify the shape of the hearing aid, earmoulds, or tubing yourself.
i Tip: It may be helpful to pull your ear up and outward with your op-
posite hand during insertion.
Low battery warning
When the batteries are low on power, your hearing aids reduce the volume, and play a mel-
ody until they are empty and turn off. The melody will recur every 5 minutes for SR70/80
models, and every 15 minutes for GAN90.
i NOTE: Keep spare batteries on hand.
Inserting/Removing hearing aids
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.

18 19
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 ear-
mould forward.
3. Consult your hearing care professional if you have difficulties
removing the hearing aid.
volume setting for you. Please note the setting of that particular level. To increase the
volume with the instrument fit to your ear, turn the volume control wheel up. To reduce the
volume, turn the wheel down.
Please note that your instrument has been fit by your hear-
ing care professional and that your hearing loss requires a
certain amount of amplification. This will also affect how
much you are able to increase the volume on your instru-
ment. If you want to go back to the default volume setting,
the volume control has to be set at 2,5 (between 2 and 3). If
you prefer not to use the volume wheel your hearing care
practitioner can disable the volume control.
Operation of the hearing aid

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.
The following suggestions may be helpful:
1. Dependent on your fitting and hearing status, either hold the
telephone up to your ear canal or hold it close to the hearing aid microphones as il-
lustrated.
2. If whistling occurs, try holding the telephone in the same position for a few seconds as
the hearing aid may be able to cancel the whistling.
3. Holding the telephone slightly away from the ear can also stop any whistling.

Telecoil (optional)
If needed, 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 sig-
nal and converts it to sound. When using a telecoil programme, the receiver of the tel-
ephone may need to be held closer to the hearing aid. The handset of the telephone may
need to be moved to slightly different positions in order to find the best reception.
iAutoPhone (Gain 90 only)
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.

24 25
i WARNING: IF A MAGNET IS SWALLOWED, SEEK IMMEDIATE ASSISTANCE FROM
A MEDICAL PRACTITIONER.
i Note: Ask your hearing care professional to enable AutoPhone as one of your pro-
grammes.
Note: Do not cover the loudspeaker opening with the magnet.
Note: If AutoPhone does not work to your satisfaction, moving the magnet to an-
other position may improve ease of use and comfort while speaking.
Note: If the hearing aids do not switch to the telephone programme every time, you
can reposition the AutoPhone magnet or add additional magnets.
Note: Use a recommended cleaning agent.
iPlace 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.

26 27
How to use AutoPhone
1. Lift the telephone to your ear.
2. When you hear a short melody, the phone programme is active.
i Note: You may need to move the telephone receiver slightly to find the best position
for reliable AutoPhone activation and good hearing on the telephone.
i AutoPhone warnings
1. Keep magnets out of reach of pets, children and mentally challenged persons.
2. The AutoPhone magnet may affect sensitive medical devices / electronic systems.
Seek advice from the manufacturers regarding appropriate safety measures when
using the AutoPhone solution near the sensitive device / equipment (pacemakers and
defibrillators) in question. If the manufacturer cannot issue a statement, we recom-
mend keeping the magnet or a telephone equipped with the magnet 30 cm (12”) away
from magnetically sensitive devices (e.g. pacemakers).
i AutoPhone precautions
1. If you experience frequent signal loss or noise during calls, move the AutoPhone mag-
net to another place on the telephone receiver.
2. Only use magnets supplied by Interton.

28 29
Teleloop systems
Many places, such as theatres, houses of worship, and schools are equipped with teleloop
systems. When using a telecoil programme with teleloop systems, sound is picked up di-
rectly. If there is no sound from the hearing aids in a teleloop system and with a telecoil
programme activated, the teleloop system may not be turned on or is not operating cor-
rectly. If a facility is not equipped with a teleloop 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 aids to items
such as television, radio, and remote microphones, may increase speech understanding for
some individuals. The sound source is connected to the hearing aids by a cable or a wireless
FM system to the audio boot. This accessory connects to the bottom of the hearing aids, and
once properly clicked into place, the hearing aids switch to DAI automatically.

your hearing aids.
1. Keep your hearing aids dry and clean.
2. Open the battery door to dry out your hearing aids when you are not wearing them.
3. Wipe the hearing aids with a soft cloth after use to remove grease or moisture.
4. Do not wear your hearing aids when putting on cosmetics, perfume, after-shave, hair
spray, suntan lotion etc. These might discolour the hearing aid or get into the hearing
aid causing damage.
5. Do not immerse your hearing aid in any liquid.
6. Keep your hearing aids away from excessive heat and direct sunlight. The heat may
deform the shell, damage the electronics and deteriorate the surfaces.
7. Do not swim, shower or steam bathe while wearing your hearing aids.

34 35
Daily maintenance
It is important to keep your hearing aid clean and dry. On a daily
basis, clean the hearing aids using a soft cloth or tissue.
In order to avoid damage due to humidity or excessive perspira-
tion, the use of a drying kit is recommended. Some drying kits are
electric, and in addition to thoroughly drying out hearing aids, they
help sanitize.
iCleaning earmoulds
1. Detach the earmould and attached tubing from the hearing aids prior to
cleaning.
2. Use a mild soap to clean the earmould and rinse with lukewarm water.
3. Dry the earmould thoroughly. Use the airbulb and cleaning wire to re-
move residual water and debris from the tubing.
i Note: Earmould tubing may become stiff, brittle, or discoloured over time. Contact
your hearing care professional regarding tube changes.

Temperature test, transport and storage information
Interton Hearing Aids are subjected to various tests in temperature and damp heating
cycling between -25°C (-13°F) and +70°C (+158°F) according to internal and industry stand-
ards.
During transport or storage, the temperature should not exceed the limit values of -20°C
(-4°F) to +60°C (+140°F) and relative humidity of 90% RH, non-condensing (for limited
time). The air pressure between 500 hPa and 1,100 hPa is appropriate.

38 39
iGeneral warnings
1. If a hearing aid is broken, do not use it.
2. Consult a hearing care professional:
• If you think there may be a foreign object in your ear canal
• If you experience skin irritation
• If excessive earwax accumulates with the use of the hearing aid
3. Different types of radiation, e.g. from NMR, MRI or CT scanners, may damage hearing
aids. It is recommended not to wear hearing aids during these or other similar proce-
dures. Other types of radiation, such as burglar alarms, room surveillance systems,
radio equipment, mobile telephones, contain less energy and will not damage hear-
ing aids. However, they have the potential to momentarily affect the sound quality or
temporarily create undesired sounds from hearing aids.
4. Do not wear hearing aids in mines, oil fields, or other explosive areas unless those
areas are certified for hearing aid use.
5. Do not allow others to use your hearing aids.
6. 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.
7. Hearing aids should be used only as prescribed by your hearing care professional.
Incorrect use may result in sudden and permanent hearing loss.
8. 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. There may be a risk of impairment of
the remaining hearing.
9. External devices connected to the electrical input must be safe according to the
requirements of IEC 60601-1-1, IEC 60065, or IEC 60950-1, as appropriate (wired con-
nection, f.ex. HI-PRO, SpeedLink).
