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 performance 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 standby 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 instrument) 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 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 instrument. 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 directional 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 healthcare 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 dislodge 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.
