4 5Warnings 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 healthcare 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 healthcare professional and contact your physician. In the unlikely case that any parts remain in the ear canal aer the removal of the hearing aid, contact a physician immediately. Remove your hearing aids for CT and MRI scans or for other electromagnetic procedures. 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 healthcare professional to ensure the maximum output of your hearing aids is suitable for your particular hearing loss.Magnet warnings Be sure the magnet is securely axed to the telephone. Keep loose magnets out of reach of children and pets.
6 7 If the magnet falls into your ear, contact your hearing healthcare professional. If the magnet is swallowed, contact your physician immediately. The magnet may aect some medical devices or electronic systems. Always keep the magnet (or the telephone equipped with the magnet) at least 30 cm (12”) away from pacemakers, credit cards, floppy disks or other magnetically sensitive devices. Too high distortion during dialing or phoning may mean that the phone handset is stressed by the magnet. To avoid any damage, please move the magnet to another place on the telephone receiver.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.Precautions 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 cell phones can create interference (a buzzing sound) in hearing aids. If you experience interference from a cell 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 cell phone and move away from it.
9Putting your hearing aids on your earsYour hearing aids may be color-coded with an indicator that is visible when the battery door is open: red = right ear; blue = le ear. Hearing aids with domes1. Hold the wire where it attaches to the dome and gently push the dome into your ear canal. The wire should lie flush against your head and not stick out.2. Place the hearing aid over the top of your ear.3. Place the retention piece in your ear so it rests at the bottom of the opening of your ear canal.1.2.3.Note to hearing healthcare professional Domes should never be tted on patients 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 ear mold.LabelingThe serial number and year of manufacture are located inside the battery door.
10 11Hearing aids with custom shells 1. Hold the custom shell between your thumb and index nger. The opening should be pointing in towards your ear canal with the hearing aid resting upwards above your ear. 2. Carefully insert the custom shell into your ear. The shell should t into your ear snugly and comfortably.3. Place the hearing aid over the top of your ear.1.2.3.Turning your hearing aids on and o Your hearing aids have a three-position battery door that acts as an on/o switch and that allows access to the battery compartment.1. On: Close the battery door fully. Note: It may take ve seconds before the hearing aid turns on. Your hearing healthcare professional can increase the start up delay if required.2. O: Partially open the battery door. 3. Open: Fully open the battery door to access and change the battery. Note: When turning your hearing aid on and o while it is on the ear, grasp the top and bottom of the hearing aid with your index nger and thumb. Use the index nger of your opposite hand to open and close the battery door.1.1.2.3.
12 13Battery informationTo replace the battery, fully open the battery door for access to the battery compartment.Low battery warningTwo long beeps indicate the hearing aid battery is low. Aer the low battery warning, sounds may not be as clear. This is normal and can be xed by changing the batteries in the hearing aids.If you are not able to hear the low battery warning, your hearing healthcare professional can change its pitch or loudness. If you prefer, it can be turned o entirely. Your hearing aids are designed to generate a low battery warning every 30 minutes until you change the batteries, but depending on the condition of the batteries, they may die before another low battery warning occurs. Therefore, it is recommended that the batteries are replaced as soon as possible once you hear the low battery warning.Replacing the battery1. Gently swing out the battery door with your ngernail. 2. Push the battery with your thumb and index nger towards the open side, and remove.3. Insert the new battery into the battery compartment with the plus (+) sign on the battery facing the same way as the plus (+) sign on the edge of the battery door. This will ensure that the battery door closes properly. Note: If the battery is inserted incorrectly, the hearing aid will not turn on.4. Close the battery door.1.2.3.4.
14 15Caring for batteriesAlways discard batteries in a safe and environmentally friendly way.To prolong battery life, remember to turn your hearing aids o when not in use, especially when asleep.Remove the batteries and keep the battery door open while hearing aids are not being worn, especially when asleep. This will allow internal moisture to evaporate.Tips for wearing hearing aids for the rsttime• Start in a quiet room at home rst to get used to the new sound quality. Sounds like the ticking of a clock, the humming of the computer, the beep of the microwave or the rustling of clothes or paper may seem loud to you at rst, because you have not been hearing them properly for a long time.• Read aloud to yourself and learn to adjust the volume of your own voice when you are wearing the hearing aids.• Talk to dierent people and learn how to distinguish between dierent sound patterns again.• It will take some time before you are completely used to your hearing aids and can fully enjoy the benets.• Wear your hearing aids for as many hours a day as you can, and for a little longer each day.
16 17• Make notes at the back of this booklet, write down dicult situations and describe what any unpleasant noises were like. This information will help your hearing healthcare professional to ne-tune the hearing aids better for your needs.• Involve your family and friends in this familiarization period. For example, ask someone to set the television to a comfortable volume.• When you are beginning to get used to wearing the hearing aids, wear them in more dicult listening environments such as the oce, at parties or in restaurants. This can be dicult even for people who can hear normally. Give yourself time to regain your ability to hear in these dicult situations.• Make your hearing aids part of your everyday life and be patient with yourself while you are learning to hear sounds correctly.Tinnitus masker Unitron’s tinnitus masker is a broadband sound generator available on the Unitron North hearing aid platform. 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.Tinnitus masker warnings Air conduction hearing aids with Unitron’s tinnitus masker are to be tted by a hearing healthcare professional familiar with the diagnosis and management of tinnitus.
18 19 Should you develop any side eects while using Unitron’s tinnitus masker, you should discontinue use of the device and seek a medical evaluation. Side eects include headaches, nausea, dizziness, heart palpitations or decrease in auditory function (such as decreased tolerance to loudness, speech not as clear or worsening of tinnitus). The volume of Unitron’s tinnitus masker can be set to a level which could lead to permanent hearing damage when used for a prolonged period of time. Should the tinnitus masker be set to such a level in your hearing aid, your hearing healthcare professional will advise you of the maximum amount of time per day you should use the tinnitus masker. The tinnitus masker should never be used at uncomfortable levels.Important information Unitron’s tinnitus masker generates sounds that are used as part of your personalized tinnitus management program to provide temporary relief from tinnitus. It should always be used as prescribed by a hearing healthcare professional who is familiar with the diagnosis and treatment of 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 that medically treatable conditions, which may be causing tinnitus, are identied and treated prior to using a sound generator. Unitron’s tinnitus masker is intended for adults 18 years of age or older who have both hearing loss and tinnitus.

You can use many phones by simply holding the receiver to your ear, without the need to change to a dedicated telephone program on your hearing aid. You may need to move the handset slightly up or back to nd the position that sounds best to you.Depending on the phone type you use, your hearing healthcare professional might have selected a dedicated phone program on your hearing aids. Your hearing aids may have an automatic telephone program (easy-t feature), which automatically switches to a dedicated telephone program when a telephone receiver is brought close to one of your hearing aids. You will hear a short melody to indicate you are in the telephone (easy-t) program.When the receiver is moved away from the hearing aid, it will automatically return to the previous listening program. If the hearing aid does not switch to the telephone program
24 25automatically when the telephone receiver is held to the ear, the magnet for easy-t hearing aids should be attached to the telephone receiver. The magnet is designed to strengthen the magnetic eld at the ear piece of hearing aid compatible telephones.To ax the optional magnet:1. Clean the telephone receiver. Hold the magnet near the “listening end” of your telephone receiver and release it. The magnet will flip to the appropriate side and seek the optimal position on the telephone receiver.2. Place the double-sided tape in this optimal position on the telephone receiver. 3. Attach the magnet to the tape.1.2.3. Your hearing healthcare professional may also have set up a phone program that you can access through the push button on your hearing aids, or through your optional remote control.If your hearing aids are congured to work with the wireless uDirect™  or uStream streamers, you might benet from a Bluetooth® hands free option. Refer to the uDirect or uStream user guide for more information. The Binaural Phone feature enables you to hold a phone to one ear and hear the sound clearly in both. No accessories are required.
26 27Protecting your hearing aids• Open the battery door when not in use.• Always remove your hearing aids when using hair care products. The hearing aids can become clogged and cease to function properly.• Do not wear your hearing aids in the bath or shower or immerse them in water. • If your hearing aids do become wet, do not attempt to dry them in an oven or microwave. Do not adjust any controls. Open the battery doors immediately, and allow your hearing aids to dry naturally for 24 hours.• Protect your hearing aids from excessive heat (hair dryer, vehicle glove box or dashboard).• Ensure you do not twist or squeeze the wire when your hearing aids are placed in their case. • Regular use of a dehumidier, such as a Dri-Aid kit, can help prevent corrosion and prolong the life of your hearing aids. • Do not drop your hearing aids or knock them against hard surfaces.Cleaning your hearing aidsUse a so cloth to clean your hearing aid at the end of each day, and place it in its case with the battery door open to allow moisture to evaporate. Regular cleaning of the microphone ports with the supplied cleaning brush will ensure that your hearing instrument will maintain its sound quality. Your hearing healthcare professional can demonstrate this for you. Ear wax is natural and common. Ensuring your hearing aids are free of ear wax is an important step in your daily cleaning and maintenance routine. Never use alcohol to clean your hearing aids, custom molds or domes. Do not use sharp tools to dislodge ear wax. Sticking household items into your hearing aids or custom molds can seriously damage them.
28 29Cleaning your custom shells and domesClean the domes and shells on the outside daily with a damp cloth. Avoid getting any water in and around the speaker units (microphone shields) and custom shells. Note: The wires, speakers, domes or custom shells should never be rinsed or submerged in water as water drops may block sound or damage the electrical components of the hearing aids.Domes should be replaced by your hearing healthcare professional every 3-6 months or when they become sti, brittle, or discolored.If your shells require further cleaning, the speaker waxguard may be plugged and require replacing. See your hearing healthcare professional.Signature features of your hearingaidsBinaural PhoneThe Binaural Phone feature enables you to hold a phone to one ear and hear the sound clearly in both ears. No accessories are required.uDirect 3, uStream and uTV The uDirect, uStream and uTV™ are optional accessories for your hearing aids.• uDirect and uStream are streamers that provide easy, hands-free access to Bluetooth enabled devices, such as mobile phones.

36 37Warning to hearing aid dispensers (tocomplywith the U.S. Food and Drug Administration (FDA) regulations) 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 signicant 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 tting 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.Licensed physicians who specialize in diseases of the ear are oen referred to as otolaryngologists, otologists or otorhinolaryngologists. The purpose of medical evaluation is to assure that all medically treatable conditions that may aect hearing are identied 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 t a hearing aid to your individual needs. If you have reservations about your ability to adapt to amplication, you should inquire about the availability of a trial-rental or purchase-option program. Many hearing aid dispensers now oer programs that permit you to wear a hearing aid for a period of time for a nominal fee aer 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 who is qualied by training and experience to assist in the evaluation and rehabilitation of a child with hearing loss is recommended.
