Thank you for selecting an Interton hearing system. We are proud of our hearing products and are
confident you have chosen one of the best products available. Please familiarize yourself with the
information in this guide. It contains important instructions for proper use and care, technical perfor-
mance information, and other general information about your hearing system. Your hearing system
has been adjusted to your particular hearing loss. Your hearing healthcare professional will explain
these adjustments and the special features of your particular model.
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.
•Begin by wearing your system for short periods of time in quiet environments.
•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.
Following 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/Off Function
The door to the battery compartment serves as the On/Off
switch for your hearing instrument. When the door is fully
closed, the instrument is on. To turn the instrument off, press
the tab on the base of the instrument with your fingertip until
the battery door snaps partly open, then put your fingernail
under the nail grip and pull gently to open it completely.
Tip: To reduce battery consumption,
turn the instrument off when it is not in use. switch off the instrument

Stand-By Mode
Stand-by mode reduces battery consumption since only a small amount of power is
used. When in stand-by mode, the hearing instrument will not deliver sound to the ear.
If your hearing instrument has a Memory Selector, you can put the instrument into stand-
by mode by holding down the Memory Selector for five seconds. You will hear a series
of beeps, indicating that the instrument is now in stand-by mode.
To return to functional mode, simply press the Memory Selector once.

9
Volume control
Your instrument has a fully automatic volume control. Therefore,
it should not be necessary to control the amplification (volume)
manually.
However, the volume control wheel provides you with the ability
to adjust the amplification to your liking.
Use your index finger to adjust the volume, moving the wheel
horizontally or upwards to increase and downwards to decrease
the volume.
During the fitting of the instrument, your hearing care practitioner will have chosen an
optimal volume setting for you. When switching the instrument on, the volume will have
this optimal setting.
•To prevent unintended usage by paediatric or physically or mentally challenged users,
the volume control must, if enabled, be configured to only provide a decrease of the
sound generator output level.
•If you prefer not to use the volume toggle your hearing care practitioner can switch the
volume control off

10
Changing Memory Programs
Hearing instrument memories are used to store settings optimal
in different listening situations. Your hearing healthcare professio-
nal may have programmed multiple memories into your hearing
instruments to accommodate your lifestyle needs.
For future reference, ask your hearing health professional to fill in
your memory program information on the notes page at the back
of this guide.
Whenever the hearing instrument is turned on, Memory 1 is automatically activated.
Memories can then be selected by pushing the Memory Selector button on the instru-
ment.
Your hearing instrument may have up to 3 programs. Special tones will indicate which
memory has been activated. One tone will sound when Memory 1 is activated, two
tones will sound when Memory 2 is activated, etc. Memories are always activated in
sequence, for example, with three memories: 1 to 2, 2 to 3, 3 to 1.
Consult your hearing healthcare professional if the memory programs in your hearing
instruments need to be reconfigured.

11
Dual microphone system (for SA70-D, SA80-D)
If you want to listen to a person in a noisy environment, the microphones in your hearing
instrument can help you to concentrate on the speech. If the microphones are in the di-
rectional mode the background noise will be attenuated. In this mode the sounds in front
of you will be enhanced, so you can hear better the speech of the person you look at.
Your hearing care practitioner can program the device in the required modes.

12
Proper Placement in the Ear
Inserting the Dome and BTE Instrument:
•Hold your hearing instrument by the tube, right where it bends.
•Hang the instrument over the top of your ear so that the housing portion is behind
your ear and the dome is in front.

13
•Push the dome into your ear until it sits comfortably and the tube lies flat against
the side of your head. Note: When the dome is placed correctly, you should not see
the tube sticking out when looking directly into a mirror.
•If you have not already turned on your hearing instrument, switch it on by closing
the battery door.
If you need further help, your hearing healthcare professional will be glad to show you
how to insert your hearing instrument correctly.
Note: If your hearing instrument irritates your ear in any way and prevents you from
wearing your hearing instrument, please contact your hearing healthcare professional.
Never attempt to modify the shape of your hearing instrument yourself.

14
Inserting the Standard Earmould and BTE Instrument:
•Put your earmould between your thumb and index finger
and position its “point” in your ear canal. - Now, slide the
earmould all the way into your ear with a gentle, twisting
movement.
•Place the hearing instrument behind your ear. Move the
earmould up and down and press gently to ensure it is
positioned correctly in the ear. You will feel when the ear-
mould is positioned correctly.
•If you have not already turned on your hearing instrument,
switch it on by closing the battery door.
Tip: Insertion of the earmould can be easier if you gently pull
your ear backward with your other hand. Opening and closing
your mouth while inserting may also be helpful.

15
Removal
To remove the hearing instrument from your ear, simply pull the tube outward with
your thumb and forefinger. Consult your hearing healthcare professional if you have
difficulty removing the hearing instrument.

16
Recognising left and right instrument
If you have two hearing instruments, they may be tuned differently. One for your left ear,
the other for your right. Do not swap them. Please pay attention to this when cleaning,
storing and inserting the instruments.

•You might want to ask your hearing care practitioner to mark your instruments with a
coloured Left and Right indication:
Left is blue and Right is red.

18
Using the Telephone While Wearing your Hearing System
Close proximity to a telephone can sometimes cause hearing in-
struments to make a squealing sound, also known as feedback.
To reduce the potential for this problem, your system is equipped
with feedback suppression, which greatly reduces the chance of
feedback. Further measures to avoid feedback include positioning
the phone close to the hearing instrument, but not directly on the
instrument. If there is feedback, it may take a few seconds for
the instrument’s signal processing to adapt. This technique may
require practice.
Using the Telecoil
Your hearing system has a built-in telecoil, and your hearing healthcare professional may
have programmed one of your listening programs to take advantage of it. When a telecoil
is activated, the hearing instrument will only detect and process sounds from coming
from the telephone.
To activate the telecoil you will need to use the memory selector to activate the appro-
priate memory.

19
To use the telephone while the telecoil is activated, position the telephone near, but not
directly on the instrument. You may need to re-position to find the best reception.
Cellular Phone and Hearing Instrument Compatibility
Hearing instrument performance with cellular phones may vary based on the individual
hearing system or the cell phone being used. If your hearing system and cell phone are
not compatible you may experience a buzzing or clicking noise while using the two in
conjunction. If this is the case with your current hearing system and cell phone, consult
with your hearing healthcare professional to see if there are options to improve the sound
quality
Measures you can take to prevent this situation:
•When purchasing a hearing system, be sure to test it with your existing phone to
determine compatibility.
•When shopping for a new cell phone, be sure to test it with your hearing system
before purchasing.
For additional guidance, please consult your cell phone provider.

Using Assistive Listening (Tele-Loop) Systems
Many gathering places are equipped with assistive listening (tele-loop) systems, for
example, in schools, theaters and houses of worship. To take advantage of a tele-loop
system, select the telecoil program. When the telecoil program has been selected,
you will be able to hear a clean sound signal via the tele-loop system. If the instru-
ment goes dead in the telecoil program, this may be because the loop system is not
operating.
If a school, theater or house of worship does not have a tele-loop system, try and sit
as close as possible to the front and use one of the microphone programs.
