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, put your fingernail under the nail grip
and pull gently to open the battery door.
Tip: To reduce battery consumption, turn the instrument off
when it is not in use.
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.
Volume Control
Your hearing instrument may have a volume control. When using your
hearing instrument, you can increase the volume by turning the volume
control forward (toward your face when you are wearing the instru-
ment) and reduce volume by turning it backward.
For each volume step, you will hear a “beep” signal indicating the
change. The loudness of the “beeps” will increase as you turn the
volume up and decrease as you turn it down. If you reach the upper
or lower limit of the volume control range, there will be a different type of “beep” signal
with a lower pitch.

Changing Memory Programs
Hearing instrument memories are used to store settings optimal in different listening
situations. Your hearing healthcare professional may have programmed multiple memo-
ries 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 4,
4 to 1.
Consult your hearing healthcare professional if the memory programs in your hearing
instruments need to be reconfigured.
Dual microphone system
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.
Depending on your hearing instrument and the setting chosen by you and your hearing
care practitioner switching to and from directional mode can be done automatically.

Proper Placement in the Ear
• There is a blue indicator for left ear instruments, and a red
indicator for right ear instruments.
• Hold the instrument with your thumb and forefinger,
either on the sides (as shown) or above and below.
• Insert the instrument into your ear canal.
Do not force the instrument beyond a comfortable point.
• Switch on your hearing instrument.
Tip: Insertion 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.
If you need further help, your hearing healthcare professional will be glad to show you
how to insert your hearing instrument correctly.
Note: If the instrument irritates your ear in any way, please contact your hearing healt-
hcare professional. You should never attempt to modify the shape of the custom shell
yourself.
Removal
• Gently massage behind your earlobe with an upward and downward motion to dis-
lodge the instrument.
• Place your thumb on the bottom and forefinger on the top of the instrument, and
carefully remove the instrument out of your ear canal with a slight “corkscrew”
motion.
By experimenting, you may find a method that is easier for you. Consult your hearing
healthcare professional if you have difficulty removing the hearing instrument.

Using the Telephone While Wearing your Hearing System
Close proximity to a telephone can sometimes cause hearing
instruments 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.
The Telecoil Feature (Optional)
If your hearing system has a built-in telecoil, your hearing healthcare professional can pro-
gram one of your listening programs to take advantage of it. When a telecoil is activated,
the hearing instrument will only detect and process sounds coming from the telephone.
To activate the telecoil you will need to use the memory selector to activate the appro-
priate memory.
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 de-
termine compatibility.
• When shopping for a new cell phone, be sure to test it with your hearing system be-
fore 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.
Removing/Inserting the Battery
Open the battery door by putting your fingernail under the nail
grip and pulling gently until the battery door is completely open.
Remove the used battery from the battery compartment.
Tip: Hold the instrument over a table or a soft surface in case
the battery falls out.
Remove the film from a new battery and place the new battery
into the battery compartment, matching the plus (+) sign on flat
side of the battery to the plus sign in the battery compartment.
A magnifying glass and good lighting may be helpful in seeing these small markings.
Your hearing instrument can only use a particular size battery. ITC instruments will
require either size 10A or 312 batteries. ITE instruments will require either size 13 or
312 batteries. For future reference, record the correct battery size for your hearing
instruments on the service pages at the back of this guide.
Close the battery compartment tightly but do not use force - it should close very easily.
Your hearing system should now be on.

Tip: Removing the battery when the instrument is not being worn will help prevent
corrosion of the battery contacts.
Corrosion can decrease efficiency, causing excessive battery consumption.
Note: A weak battery will cause reduced system performance.
Low Battery Warning
Your hearing system features a Low Battery Warning function to give you notice when
your battery is getting low.
The instrument will signal when the battery power decreases to a certain level, and
will continue beeping until the instrument automatically switches off.
Tip: It is helpful to keep spare batteries with you in case you need them.
Battery Safety
• Dispose of used batteries properly.
• Keep batteries out of reach of children or persons with diminished mental capacity.
• Keep batteries away from pets.
• Do not place batteries in your mouth. If a battery has been swallowed,
consult a physician immediately.
To prevent batteries from leaking or exploding:
• Do not expose batteries to temperature extremes.
• Do not dispose of batteries in fire.
• Do not attempt to recharge batteries which are not specifically designated
rechargeable, or reverse a battery’s polarity.

Cleaning the Instrument
The surfaces of your instruments should be cleaned after every use. Use a soft cloth
to remove dirt, dust, earwax and residue from cosmetics or colognes. Keeping the
instruments as clean as possible will help avoid
costly repairs.
Only use cleaning products recommended by your
hearing healthcare professional. Please refer to
“Things that Can Damage Your Hearing System”
for more information.
Cleaning the Sound Inlet and Outlet
Refer to the diagram on pages 4-5 to locate the
sound inlet and sound outlet on the hear ing instrument.
Cleaning the Microphone Sound Inlet
Keeping the sound inlet clean will allow the microphone
to function properly. Use the soft brush provided with
your hearing system to remove dust or other debris
from the sound inlet.
Cleaning the Sound Outlet
Earwax or other debris may also collect in the sound outlet. Unless filters
have been installed to block the debris, the cleaning loop provided with your
hearing instrument can easily be used to remove this material.
When using this tool, be careful not to damage or pull the tubing placed at the opening
of the sound outlet. If this is pulled out, the hearing instrument may need to be returned
for repair.
Your hearing healthcare professional can instruct you on how to properly use the clean ing
loop and soft brush.
Note: If your hearing system has been equipped with filters, please refer to the “Ear-
wax Management” section.
