Warnings

Changes or modications to the hearing

aids that are not explicitly approved by

the manufacturer are not permitted. Such

changes may damage your ear or the hearing

aids.

The intended use of hearing aids is to

amplify and transmit sound to the ears and

hereby compensate for impaired hearing.

The hearing aids (specially programmed for

each hearing loss) must only be used by the

intended person. They should not be used

by any other person as they could damage

hearing.

Hearing aids should only be used as

directed by your physician or hearing care

professional.

Hearing aids will not restore normal

hearing and will not prevent or improve a

hearing impairment resulting from organic

conditions.

Do not use your hearing aids in explosion

hazard areas.

Allergic reactions to hearing aids are

unlikely. However, if you experience itching,

redness, soreness, inflammation or a burning

sensation in or around your ears, inform your

hearing care professional and contact your

physician.

In the unlikely case that any parts remain in

the ear canals aer the removal of the hearing

aids, contact a physician immediately.

Hearing programs in the directional

microphone mode reduce background noises.

Please be aware that warning signals or

noises coming from behind, e. g. cars, are

partially or entirely suppressed.

These hearing aids are not for children

below 36 months. The usage of this device

by children and individuals with cognitive

impairment should be supervised at all times

to ensure their safety. The hearing aids are

small devices and contain small parts.

6 7

Do not leave children and individuals with

cognitive impairment unsupervised with

these hearing aids. If swallowed, consult

a physician or hospital immediately as

the hearing aids or their parts can cause

choking.

Do not make a wire connection from your

hearing aids to any external audio sources

like radio etc. That could cause injuries on

your body (electric shock).

The following is only applicable for persons

with active implantable medical devices

(i.e. pacemakers, debrillators, etc.):

- Keep the wireless hearing aids at least 15

cm (6 inches) away from the active implant.

- If you experience any interference, do not

use the wireless hearing aids and contact

the manufacturer of the active implant.

Please note that interference can also

be caused by power lines, electrostatic

discharge, airport metal detectors etc.

Special medical or dental examination

including radiation described below, may

adversely aect the correct functioning of

your hearing aids. Remove and keep them

outside the examination room/area before

undergoing:

- Medical or dental examination with X-ray

(also CT scan).

- Medical examinations with MRI/NMRI

scans, generating magnetic elds.

- Hearing aids don’t need to be removed

when passing security gates (airports etc.).

If X-ray is used at all, it will be in very low

doses, and will not aect the hearing aids.

Use of this equipment adjacent to or

stacked with other equipment should be

avoided because it could result in improper

operation. If such use is necessary, this

equipment and the other equipment should

be observed to verify that they are operating

normally.

8 9

Use of accessories, transducers and cables

other than those specied or provided

by the manufacturer of this equipment

could result in increased electromagnetic

emissions or decreased electromagnetic

immunity of this equipment and result in

improper operation.

Your hearing aids operate in the frequency

range of . GHz–.8 GHz. When flying

please check if flight operator requires

devices to be switched into flight mode.

Portable RF communications equipment

(including peripherals such as antenna

cables and external antennas) should be

used no closer than 30 cm (12 inches) to

any part of the hearing aids, including

cables specied by the manufacturer.

Otherwise, degradation of the performance

of this equipment could result.

Special care should be exercised in wearing

hearing aids when maximum sound

pressure levels exceed 132 decibels. There

may be a risk of impairing your remaining

hearing. Speak with your hearing care

professional to ensure the maximum output

of your hearing aids is suitable for your

particular hearing loss.

Note to hearing care professional

Domes should never be tted on clients with

perforated eardrums, exposed middle ear

cavities, or surgically altered ear canals. In

the case of such a condition, we recommend

to use a customized earmold.

Battery warnings

Never leave hearing aids or batteries

where small children and pets can reach

them. Never put hearing aids or batteries

in your mouth. If a hearing aid or battery is

swallowed, call a physician immediately.

10 11

Precautions

These hearing aids are water resistant

and not waterproof. They are designed to

withstand normal activities and occasional

accidental exposure to extreme conditions.

Never immerse your hearing aids in water.

These hearing aids are not specically

designed for extended periods of water

submersion on a continual basis, that is

worn in activities such as swimming or

bathing. Always remove your hearing aids

before these activities, as the hearing aids

contain sensitive electronic parts.

Protect your hearing aids from heat (never

leave near a window or in the car). Never

use a microwave or other heating devices

to dry your hearing aids (due to risk of

re or explosion). Ask your hearing care

professional about suitable drying methods.

The dome should be changed every three

months or when it becomes sti or brittle.

This is to prevent the dome from detaching

from the tube spout during insertion into or

removal from the ear.

Do not drop your hearing aids. Dropping

onto a hard surface can damage your

hearing aids.

The use of hearing aids is only part of

hearing rehabilitation; auditory training and

lip reading instruction may be required as

well.

In most cases, infrequent use of hearing

aids does not provide full benet. Once you

have become accustomed to your hearing

aids, wear your hearing aids everyday all

day.

Your hearing aids use the most modern

components to provide the best possible

sound quality in every listening situation.

However, communication devices such

as digital mobile phones can create

12 13

interference (a buzzing sound) in hearing

aids. If you experience interference from a

mobile phone being used close by, you can

minimize this interference in a number of

ways. Switch your hearing aids to another

program, turn your head in a dierent

direction or locate the mobile phone and

move away from it.

Labeling

The serial number and year of manufacture are

located inside the battery door.

Mobile phone compatibility rating

Some hearing aid users have reported a buzzing

sound in their hearing aids when they are using

mobile phones, indicating that the mobile

phone and hearing aids may not be compatible.

According to the ANSI C63.19 standard (ANSI

C63.19-2011 American National Standard

Methods of Measurement of Compatibility

Between Wireless Communications Devices and

Hearing Aids), the compatibility of particular

hearing aids and a mobile phone can be

predicted by adding the rating for the hearing

aid immunity to the rating for the mobile phone

emissions. For example, the sum of the hearing

aid rating of 4 (M4) and a telephone rating of 3

(M3) would result in a combined rating of 7. Any

combined rating that equals at least 5 would

provide “normal use”; a combined rating of 6 or

greater would indicate “excellent performance.”

The immunity of these hearing aids is at least

M4. The equipment performance measurements,

categories and system classications are based

upon the best information available but cannot

guarantee that all users will be satised.

14 15

The performance of the individual hearing

aids may vary with individual mobile phones.

Therefore, please try these hearing aids with

your mobile phone or, if you are purchasing a

new phone, please be sure to try it with your

hearing aids prior to purchase.

Tinnitus masker

Tinnitus masker uses broadband noise to

provide temporary relief of tinnitus.

Tinnitus masker warnings

The tinnitus masker is a broadband sound

generator. It provides a means of sound

enrichment therapy that can be used as

part of a personalized tinnitus management

program to provide temporary relief from

tinnitus.

The underlying principle of sound

enrichment is to provide supplementary

noise stimulation which can help defocus

your attention from your tinnitus and avoid

negative reactions. Sound enrichment,

coupled with instructional counseling, is an

established approach to managing tinnitus.

Air conduction hearing aids with the tinnitus

masker are to be tted by a hearing care

professional familiar with the diagnosis and

management of tinnitus.
