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.
• It takes time to get used to a hearing aid. It may help to begin by wearing your hearing aid for shor t
periods – even as little as 15 minutes – and then gradually building up your wearing time. In a way, it’s
no different than adjusting to contact lenses. Speak to you hearing care professional, who can design
a schedule tailored just for you.
• 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.

Getting started
On&Off function
1. When the battery door is closed, the hearing instrument turns on, and
the default program will be activ ated.
2. To turn off the hearing instrument, open the battery door. Many
individuals can use their fingernail to pull it open.
Whenever the hearing instruments are not in use, remember to turn
i
them off to avoid unnecessary battery consumption.
Delayed activation
Hearing instruments 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
Delayed on-activation. This function will delay the time in which the hearing instruments turn on by several
On
Off
seconds after the battery compartment is closed. With Delayed on-activation, a beep will be heard for each
second of the delay period.
Inserting/Replacing the battery
1. Open the battery door completely by using your fingernail.
2. Remove the used batter y if present. Insert the new battery with the positive side
in the correct position.
3. Gently close the battery door.
Always use new Zinc-Air batteries that have a minimum remaining shelf-life of 1 year.

Page 10
i WARNING
1. Remove the batteries to prevent leakage when the hearing instruments are not in use for an extended
period of time.
2. Do not attempt to recharge batteries (Zinc Air) which are not specifically designated as rechargeable
because they may leak or explode.
3. Do not place batteries in your mouth. Consult a physician immediately if a batter y has been swallowed, as they can be harmful to your health.
4. Keep batteries away from pets, children and individuals who are mentally challenged.
5. Do not attempt to dispose of batteries by burning them. Used batteries are harmful to the environment. Please dispose of them according to local regulations or return them to your hearing care
practitioner.
18
Low battery indicator
Your hearing care professional can set your hearing instrument to give an acoustical indication when the
battery is reaching its end of life. The hearing instrument will reduce amplification and emit a melody if battery power gets too low. This signal will recur every five minutes until the hearing instrument automatically
switches of f. It is recommended that you keep spare batteries on hand.
Low battery indicator (instruments paired with accessories only)
Active usage of the Interton wireless accessories (Remote Control, Phone Clip and TV Streamer) requires
more battery power from the hearing instruments than when these are working on their own. When the
battery in the hearing instrument has depleted to a level at which use of the Interton TV Streamer T V and
Phone Clip cannot be supported, the hearing instrument will play two sets of descending tones. After
this, your hearing instrument and Inter ton Remote Control will continue to work as usual, but you will not
be able to use your Interton TV Streamer and Phone Clip. At some point the battery level will not support
the remote control either and you will once again hear the descending tones. The hearing instruments will
continue to work as usual. Once a new battery is inserted, full operation of the accessories will resume.

automatically switched the hearing instrument to your telephone programme. Initially, you may need to
move the telephone receiver slightly to find the best position for reliable AutoPhone activation and good
hearing on the telephone. When remove you the telephone receiver AutoPhone will stay activated for a
few seconds to avoid accidental switching of f. After that hearing instrument will switch to previously used
environmental programme.
I WARNING
AutoPhone warnings
1. Keep magnets out of reach of pets, children and mentally challenged persons. If a magnet is
swallowed, please seek advice from a medical practitioner.
2. The AutoPhone magnet may affect some medical devices or electronic systems. The manufacturer of
any magnetically sensitive devices (e.g. pacemakers) should advise you regarding appropriate safety
precautions when using your hearing instrument and magnet in close proximity to the medical device
or electronic system in question.
3. if the manufacturer cannot issue a statement, we recommend keeping the magnet or a telephone
equipped with the magnet 30 cm (12”) away from magnetically sensitive devices (e.g. pacemakers).
34
35
Page 19
I CAUTION
AutoPhone precautions
1. High distortion during dialing or phoning may mean that the magnet is not in the optimal position
relative to the telephone receiver. To avoid the issue, please move the magnet to another place on the
telephone receiver.
2. Only use magnets supplied by Interton/GN Hearing.
Telecoil (optional)
If equipped, 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 signal and converts it to sound. An
optional telephone programme may help to improve speech understanding on the telephone. When using
a telecoil programme, the receiver of the telephone may need to be held closer to the hearing instrument.
The handset of the telephone may need to be moved to slightly different positions in order to find the best
reception.

idea to put the instrument and battery in a sealed container together with a drying agent (desiccator)
overnight. Do not use the instrument until it is completely dry. Consult your hearing care professional
as to which dr ying agent to use.
7. Remove your hearing instrument when applying such things as cosmetics, perfume, aftershave, hair
spray, and suntan lotion. These might get into the instrument and cause damage.
The receiver tube
The receiver tube for most Interton products comes in three different power levels:
Small (S), Normal Power (NP) and High Power (HP/HP2). Depending on your hearing loss you have either
been fitted with the S, NP or the HP/HP2 receiver type.
For Interton Centro, the receiver tube comes in four dif ferent power levels:
Low Power (LP), Medium Power (MP), High Power (HP) and Ultra Power (UP).
The receiver tube contains the wiring to the receiver which delivers the sound to the ear canal. It is important that the receiver tube and the receiver dome/RIE mold fits correctly in your ear. If the receiver tube or
the receiver dome/RIE mould irritates your ear in any way and prevents you from wearing your hear ing instrument, please contact your hearing care pro fessional. You should never attempt to modify the shape of
the receiver tube yourself. The receiver tube and the receiver dome/RIE mould should be cleaned regularly.
Please see instructions in the next section.

How to apply domes
It is recommended that your hearing care professional change domes, as incorrect dome re place ment
could result in the dome falling out in the ear.
Mini domes
1. Push the new dome over the flanges on the receiver.
2. Make sure that the new dome is properly and securely mounted.
Standard domes
Standard domes are mounted in a similar manner to mini domes, but a few extra steps are required. Tulip
domes consist of two “petals”. It is important to note that the largest petal is the outermost petal.
To ensure this:
1. Push the largest petal away from the receiver using a finger. This bends the petal forward.
2. Then push the largest petal back, and it will be placed on top of the smaller petal.

Warranty and repairs
Interton provides a warranty on hearing instruments in the event of defects in workmanship or materials,
as described in applicable warranty documentation.
In its service policy, Interton pledges to secure functionality at least equivalent to the original hearing instrument.
As a signatory to the United Nations Global Compact initiative, Interton is committed to doing this in line
with environment-friendly best practices. Hearing instruments therefore, at Interton’s discretion, may be
replaced by new products or products manufactured from new or serviceable used parts, or repaired using new or refurbished replacement parts.
The warranty period of hearing instruments is designated on your warranty card, which is provided by your
hearing care professional.
For hearing instruments that require service, please contact your hearing care professional for assistance.
Interton hearing instruments that malfunction must be repaired by Interton qualified technician. Do not attempt to open the case of hearing instruments, as this will invalidate the warranty.
Temperature test, transport and storage information
Interton Hearing Instruments are subjected to various tests in temperature and damp heating cycling between -25° C (-13F) and +70° C (+158F) according to internal and industry standards.
During transpor t or storage, the temperature should not exceed the limit values of -20° C (-4F) to +60° C
(+140F) and relative humidity of 90% RH, non condensing (for limited time). The air pressure between 500
and 1100 hPa is appropriate.

Hearing instrument expectations
i
A hearing aid will not restore normal hearing and will not prevent or improve a hearing impairment resulting
from organic conditions
Consistent use of the aid is recommended. In most cases, infrequent use does not permit you to attain
full benefit from it.
The use of a hearing aid is only part of hearing rehabilitation and may need to be supplemented by auditory
training and instructions in lip-reading.
i Warning to Hearing Aid Dispensers (US only)
A hearing aid dispenser should advise a prospective hearing aid user to consult promptly with a licensed
physician (preferably an ear specialist) before dispensing a hearing aid, if the hearing aid dispenser determines through inquiry, actual observation, or review of any other available information concerning the
prospective user, that the prospective user has any of the following conditions:
(i) Visible congenital or traumatic deformity of the ear.
(ii) Histor y of active drainage from the ear within the previous 90 days.
66
(iii) History of sudden or rapidly progressive hearing loss within the previous 90 days.
(iv) Acute or chronic dizziness.(v) Unilateral hearing loss of sudden or recent onset within the previous
90 days.(vi) Audiometric air-bone gap equal to or greater than 15 decibels at 500 hertz (Hz), 1,000
Hz, and 2,000 Hz.
(vii) Visible evidence of significant cerumen accumulation or a foreign body in the ear canal.
(viii) Pain or discomfort in the ear.
Important Notice for Prospective Hearing Aid Users (US only)
Good health practice requires that a person with a hearing loss have a medical evaluation by a licensed
physician (preferably a physician who specializes in diseases of the ear) before purchasing a hearing
aid. Licensed physicians who specialize in diseases of the ear are often referred to as otolaryngologists,
otologists or otorhinolaryngologists. The purpose of the medical evaluation is to assure that all medically
treatable conditions that may affect hearing are identified and treated before the hearing aid is purchased.
Following the medical evaluation, the physician will give you a written statement that states that your hearing loss has been medically evaluated and that you may be considered a candidate for a hearing aid. The
67
Page 35
physician will refer you to an audiologist or a hearing aid dispenser, as appropriate, for a hearing aid evaluation. The audiologist or hearing aid dispenser will conduct a hearing aid evaluation to assess your ability
to hear with and without a hearing aid. The hearing aid evaluation will enable the audiologist or dispenser
to select and fit a hearing aid to your individual needs. If you have reservations about your ability to adapt
to amplification, you should inquire about the availability of a trial-rental or purchase-option program. Many
hearing aid dispensers now offer programs that permit you to wear a hearing aid for a period of time for a
nominal fee after which you may decide if you want to purchase the hearing aid. Federal law restricts the
sale of hearing aids to those individuals who have obtained a medical evaluation from a licensed physician.
Federal law permits a fully informed adult to sign a waiver statement declining the medical evaluation for
religious or personal beliefs that preclude consultation with a physician. The exercise of such a waiver is
not in your best health interest and its use is strongly discouraged.
Children with hearing loss (US only)
In addition to seeing a physician for a medical evaluation, a child with a hearing loss should be directed
to an audiologist for evaluation and rehabilitation because hearing loss may cause problems in language
68
development and the educational and social growth of a child. An audiologist is qualified by training and
experience to assist in the evaluation and rehabilitation of a child with hearing loss.
