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 instru-
ment. 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.
Power-on delay
Power-on delay allows you to insert the instrument in your ear without the hearing instru-
ment squealing. It delays the switch-on time by 10 seconds after closing the battery
compartment.Abeepeachsecondispresentedduringthistime.
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veseconds.Youwillhearaseries

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
•Locate and grasp the removal cord
•Pull the instrument gently from the ear.
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.

Cellular Phone and Hearing Instrument Compatibility
Hearing instrument performance with cellular phones may vary based on the indi-
vidual 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.
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.

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,

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 page 4 to locate the sound
inlet and sound outlet on the hearing 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 cleaning
loop and soft brush.
Note:Ifyourhearingsystemhasbeenequippedwithlters,pleaserefertothe“Ear-
waxManagement”section.

Earwax Management
Hearing systems are susceptible to damage or poor performance from earwax. If
appropriate, your hearing health professional will have selected and installed an ear-
wax management system on your instruments.
You will need to discuss with your hearing healthcare professional how to use the
particular earwax management system selected.
Note: If the hearing system seems to have lost power because it is not loud enough
and changing the batteries does not help, the filters may be blocked and need to be
changed.
When the Hearing System Is Not in Use
To protect your hearing system when it is not in use, always store it
inside its carrying case. When storing the hearing system for a prolonged period of
time, remove the battery to prevent damage from corrosion.
Things that Can Damage Your Hearing System
Keep in mind that some of your day-to-day routines require that you remove your
hearing system.
Moisture
Avoidgetting moistureinthehearingsystem.Itshould notbewornintheshower,
bath,orsauna.Donotsubmergetheinstrumentinwaterorotherliquids.
If perspiration or humidity is an issue, you may find it beneficial to use a drying kit
specially designed for hearing systems. To prevent damage, only use drying kits that
are approved by your hearing healthcare professional.
Temperature Extremes
Do not expose your hearing system to extremes of heat.
Some typical situations to avoid:
•Do not wear your hearing system when using a hair dryer.
