17. Important safety information
Please read the information on the following pages before using your hearing aid.
A hearing aid will not restore normal hearing and will not prevent or improve a hearing impairment resulting from organic conditions. Infrequent use of a hearing aid does not permit a user to attain full benefi t from it. The use of a hearing aid is only part of hearing habilitation and may need to be supplemented by auditory training and instruction in lipreading.
40
17.1 Hazard warnings
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.
Do not use the hearing aids in explosive areas
(mines or industrial areas with danger of explosions, oxygen-rich environments or areas where fl ammable anesthetics are handled).
Hearing aid batteries are toxic if they are swallowed!
Keep out of reach of children under 3 years. If batteries are swallowed, consult your physician immediately!
Changes or modifi cations to the hearing aid that were not explicitly approved by Phonak are not permitted. Such changes may damage your ear or the hearing aid.
If you feel pain in or behind your ear, if it is infl amed or if skin irritation and accelerated accumulations of earwax occur, please check with your hearing care professional or physician.
41
42
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.
External devices may only be connected if they have been tested in accordance with corresponding
IECXXXXX standards. Only use accessories approved by Phonak AG, to avoid any electrical shock.
This hearing aid is not for children below 36 months.
It contains small parts that can cause choking, if swallowed by children.
Keep out of reach of children under 3 years.
If swallowed, consult a physician or hospital immediately.
The following is only applicable for persons with active implantable medical devices (i.e. pacemakers, defi brillators, etc.):
Keep the wireless hearing aid 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.
Keep magnets (i.e. battery handling tool, EasyPhone magnet, etc.) at least
15 cm (6 inches) away from the active implant.
43
17.2 Information on product safety
Never immerse your hearing aid in water! Protect it from excessive moisture. Always remove your hearing aid before showering, bathing, or swimming, as the hearing aid contains sensitive electronic parts.
Protect your hearing aid from heat (never leave near a window or in the car).
Never use a microwave or other heating devices to dry your hearing aid.
Ask your hearing care professional about suitable drying methods.
When you are not using your hearing aid, leave the battery door open so that any moisture can evaporate.
Make sure that you always completely dry your hearing aid after use. Store the hearing aid in a safe, dry and clean place.
Do not drop your hearing aid! Dropping onto a hard surface can damage your hearing aid.
Always use new batteries for your hearing aid. In case a battery is leaking, replace it immediately with a new one to avoid any skin irritation. You can return used batteries to your hearing care professional.
The batteries used in these hearing aids should not exceed 1.5 Volts. Please do not use silver-zinc or Li-ion
(lithium-ion) rechargeable batteries as these may cause severe damage to your hearing aids. The table in chapter 5 explains exactly which type of battery your particular hearing aids require.
Remove the battery if you are not using your hearing aid for a long period of time.
44 45
Special medical or dental examination including radiation described below, may adversely aff 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 fi 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 aff ect the hearing aids.
46
Do not use your hearing aid in areas where electronic equipment is prohibited.
18. Important information: Cell phones
Some hearing aid users have reported a buzzing sound in their hearing aids when they are using cell phones.
According to the ANSI 63.19 (American National
Standard Methods of Measurement of Compatibility between Wireless Communications Devices and Hearing
Instruments) standard, the compatibility of a particular hearing aid and cell phone can be predicted by adding the rating for the hearing aid immunity to the rating for the cell phone emissions. The sum of the hearing aid rating (e.g. M2/T2=2) and the telephone rating
(e.g. M3/T3=3) is 5, and any combination that equals
5 will provide “normal use”; a sum of 6 or greater would indicate “excellent performance”. The equipment performance measurements, categories and system classifi cations are based upon the best information available but cannot guarantee that all users will be satisfi ed. The immunity of this hearing aid is at least
M2/T2.
47
Note: the performance of individual hearing aids may vary with individual cell phones. Therefore, please try the hearing aid with your cell phone or, if you are purchasing a new phone, be sure to try it with your hearing aid prior to purchase. For additional guidance, please ask your hearing care professional for the booklet entitled “hearing aid compatibility with digital wireless cell phones”.
48
19. For the US market only, complies with the FDA regulations
Warning to Hearing Aid Dispensers
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.
49
(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. Special care should be exercised in selecting and fitting a hearing aid whose maximum sound pressure level exceeds 132 decibels because there may be risk of impairing the remaining hearing of the hearing aid user. (This provision is required only for those hearing aids with a maximum sound pressure capability greater than 132 decibels
(dB).)
Important Notice for Prospective Hearing Aid Users
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.
50
Licensed physicians who specialize in diseases of the ear are often referred to as otolaryngologists, otologists or otorhinolaryngologists. The purpose of 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
51
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
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 since 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 a hearing loss.
52
20. Important notice for Prospective
Noise Generator users
The Tinnitus Balance noise generator is a broadband sound Generator which may have been enabled in your hearing aid. It provides a means of sound enrichment that can be used as part of a personalized tinnitus management program to provide temporary relief from tinnitus. It should always be used as prescribed by your audiologist. 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.
Good health practice requires that a person reporting tinnitus have a medical evaluation by a licensed ear physician before using a sound generator. The purpose of such an evaluation is to ensure medically treatable conditions that may be causing tinnitus are identifi ed and treated prior to using a sound generator.
53
Should you develop any side eff ects whilst using the noise generator such as headaches, nausea, dizziness or heart palpitations or experience a decrease in auditory function, you should discontinue use and seek a medical evaluation.
According to OSHA (Occupational Safety & Health
Administration, U.S. Department of Labor) regulations, the volume of the noise generator can be set to a level which could lead to permanent hearing damage when used for a prolonged period of time. Should the noise generator be set to such a level in your hearing aid, your audiologist will advise you of the maximum amount of time per day you should use the noise generator. The noise generator should never be used at uncomfortable levels.
