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 short
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.

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 (15 minutes for GAM390-DVI and GAN290-DVI) un­til the hearing instrument automatically switches off. 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 TV and
Phone Clip cannot be supported, the hearing instrument will play two sets of descending tones. After
this, your hearing instrument and Interton 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.

Telecoil (optional)

If equipped, a telecoil can be activated by your hearing care professional and accessed through one of the
additional programs. A telecoil picks up a telephone’s magnetic signal and converts it to sound. An option­al telephone program may help to improve speech understanding on the telephone. When using a telecoil
program, 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.

Tele-loop systems (optional)

Many places, such as theaters, houses of worship, and schools are equipped with tele-loop systems.
When using a telecoil program with tele-loop systems, sound is picked up directly and may improve
speech understanding. If there is no sound from the hearing instruments in a tele-loop system and with
a telecoil program activated, the tele-loop system may not be turned on or is not operating correctly. If
a facility is not equipped with a tele-loop system, sitting as close as possible to the front may be helpful.

to the hearing instruments.

3. Avoid rough handling of hearing instruments or dropping them on hard surfaces or floors.

4. Do not leave hearing instruments in or near direct heat or sunlight, such as in a hot, parked car, as
excessive heat can cause damage or deform the casing.

5. Do not wear your instrument while showering, swimming, in heavy rain or in a moist atmosphere such
as a steam bath or sauna.

6. If your instrument does get wet, or if it has been exposed to high humidity or perspiration, it should be
left to dry out overnight with the battery out and the battery compartment open. It is also a good 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
drying 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.

Cleaning earmolds

1. Remove the earmold and attached tubing from the
hearing instruments prior to cleaning.

2. Clean the earmold using a mild soap, and rinse with
lukewarm water.

3. After cleaning, dry earmolds thoroughly and remove any
residual water and debris from the tubing utilizing an air
bulb and wire loop.

i

Earmold tubing may become stiff, brittle, or discolored
over time. Contact your hearing care professional regarding
tube changes.

Scan a QR code with your

smart phone and watch a

instruction video.

Cleaning thin tubes and domes

1. Remove thin tubes from hearing instruments before cleaning by unscrewing
them counter clockwise.

2. Wipe down thin tubes and domes with a damp cloth.

3. In order to clear the thin tube of moisture and debris, push the black cleaning
rod through the thin tube, beginning at the end opposite the dome.

i

Thin tube and dome systems should be changed every three months or

sooner, should the components become stiff or brittle.

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 thin tube.

2. Make sure that the new dome is properly and securely mounted.

400080011-US-14.10-Rev.B.indd 40 03-12-2014 10:42:22

41

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 thin tube 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.

2. Different types of radiation, e.g. from NMR, MRI or CT scanners, may damage the instrument. There­fore, do not wear the instrument during these or other corresponding scanning procedures. Other
types of radiation (burglar alarms, room surveillance systems, radio equipment, mobile telephones
etc.) will not damage the instrument. They could, however, momentarily affect the sound quality or
create strange sounds from the instruments.

3. Do not wear hearing instruments in mines, oil fields, or other explosive areas unless those areas are
certified for hearing instrument use.

4. Do not allow others to use your hearing instruments. This may cause damage to the hearing instru­ments or to the hearing of the other individual.

Hearing instrument expectations

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) History of active drainage from the ear within the previous 90 days.

(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

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

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.

i High sound pressure levels

Special care should be exercised in selecting and fitting a hearing instrument(s) whose maximum sound
pressure level exceeds 132 dB SPL (with an IEC 60711:1981 occluded ear simulator), because there may
be a risk of impairing the remaining hearing of the hearing instrument user.
