A new Beltone hearing instrument Congratulations on your choice of a Beltone hearing instrument! This is an important step towards clearer hearing and better understanding. We have used all our experience with hearing instruments to help you communicate, lead an enjoyable social life and listen to the world around you. Your hearing instrument is a very advanced device. Your hearing care practitioner has tuned it to your individual needs. With a little devotion and patience you will become familiar with it.
This booklet & your instrument In this booklet you will find instructions for inserting and controlling your new hearing instrument. You will find explanations on controlling your instrument, on daily handling and on its use. Furthermore, you can read what to do if things do not live up to your expectations. We will give a few practical steps towards better hearing.
Warning to hearing care professional A hearing care professional should advise a prospective user to consult promptly with a licensed physician (preferably an ear specialist) before setting the instrument if the hearing care professional 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 dr

Switching on and off Switch your hearing instrument on by closing the battery door. Switch your instrument off by a small movement of the battery door till you feel a click. After switching on, your hearing instrument will always start in program 1. Read more on the program button on page 14. on On page 16 you will read more on the T-program. • Switch your instrument off if you are not using it. This will increase the battery life.
Changing batteries When the hearing instrument generates a warning signal it’s advisable to change your battery as soon as possible. The signal will continue as long as the battery is not changed or unless it does not run out of power, and therefore it is advisable to keep an extra battery at hand. Remove ‘dead’ battery Open the battery door by placing your fingernail or a pencil on the edge of the battery door and gently pull it down.
Warnings • Keep batteries away from children and mentally challenged persons. • Batteries can be harmful if swallowed. If you do, seek medical attention immediately. • Do not attempt to recharge batteries (Zinc Air) which are not specifically designated rechargeable as they may leak or explode. • Do not burn the batteries, as they could explode. • Replace spent batteries and do not leave them in the instrument for a prolonged period. • Used batteries are harmful to the environment.
Inserting and removing the instrument (standard earmould) Inserting the instrument • With the battery door opened in the off position take the earmould between thumb and index finger and position its ‘point’ in your ear canal. Now, slide the earmould all the way into your ear with a gentle, twisting movement. Insertion can be easier if you gently pull your auricle backwards with your other hand.
• You can as well insert the hearing instrument while in the on position. However you might experience some feedback (whistling) during the operation. This feedback can be prevented by enabling ”Delayed Activation”. Ask your hearing care practitioner about this feature. Removing your instrument • Switch off the instrument by pressing the battery door to the ‘off ’ position. • Lift the hearing instrument from behind the ear. For a moment, let it hang beside your ear.
Inserting and removing the instrument (ThinTube) Inserting the instrument • Hang the instrument over the top of the ear. • Grasp the sound tube where it bends. The dome should be placed far enough into the ear that the sound tube lies flush with your head. When the dome is placed appropriately, you should not see the sound tube sticking out when you look directly into a mirror. • If the device whistles, the most likely reason is that the dome is not placed correctly in the ear canal.
Recognising left and right instrument If you have two hearing instruments, they may be tuned differently. One for your left ear, the other for your right. Do not swap them. Please pay attention to this when cleaning, storing and inserting the instruments.
• You might want to ask your hearing care practitioner to mark your instruments with a coloured Left and Right indication: Left is blue and Right is red. indication CHG 75 / 75D / 75 Open / 75D Open / CHG 85 / 85D Setting the volume – BTE and Power BTE Your instrument has a volume control which allows you to set and control the volume manually. During the fitting of the hearing instrument, your hearing care practitioner will have chosen an optimal volume setting for you.
Program button Your hearing instrument has a push button allowing you to use up to three different listening programs, each of them suitable for certain situations. After pressing the program button, the instrument will switch program. If it was in program 1 it will switch to program 2, if it was in program 2 it will switch to program 3 etc. If program 2 or 3 are not activated, nothing will happen. Your instrument will give an audible signal after pressing the program button.
Let your hearing care practitioner fill out the following table: Program number Type of program Intended for listening situations 1 2 3 Directional microphone BTE and Power BTE can have a directional microphone function. If you want to listen to a person in a noisy environment, the micro phone in these hearing instruments can help you to concentrate on the speech. If the microphones are in the directional mode the background noise will be suppressed.
T-program Your hearing instrument has a built in function, the telecoil, enabling in many cases an improved use of the telephone and better hearing in those churches or halls where an induction loop system is installed. In order to activate this function, the telecoil program has to be selected (often available in program 2). In this program you will hear no sounds from the microphone, therefore most environmental sounds will be lost.
Hearing through an induction loop More and more public places, churches, theatres and cinemas, have induction loops systems. In these particular rooms, they transmit, wirelessly, the sound of the presenter or show. At home, radio or television can be connected to an induction loop system. Sound quality through induction loop is often better because noises from the environment are not transmitted. • Switch your instrument to the telecoil program. • Choose a good spot.
Audio input Your hearing instrument is equipped with a direct audio input facility. Direct audio input allows direct connection of sound sources, a radio, television or even school equipment, to your hearing instrument. Often, this will improve sound quality. • The sound source is connected to your instrument with a cable or a wireless FM system to an audio shoe. • The audio shoe attaches with a ’click’. When attached, the instrument will automatically switch to Direct Audio Input program.
Maintenance and cleaning Earwax (cerumen) can accumulate in and on the earmould during use. Therefore, clean your earmould regularly. Failure to do so can lead to an accumulation of earwax, impairing sound quality. Keep your hearing instrument clean and dry. Wipe the case with a soft cloth or tissue after use to remove grease or moisture. You should avoid exposing your instrument directly to moisture such as rain or water from the shower.
Cleaning the earmold • First, remove the tubing and earmold from the hearing instrument. Keep left and right instrument separated. • Remove earwax with the cleaning brush and a soft cloth. If needed, use a mild solution of soft soap and water or a special cleaning solution. Ask your hearing care practitioner for detailed instructions. • Rinse the earmold with water. Note: Do not use water or other liquid on the hearing instrument itself. • Dry the earmold with a cloth.
Cleaning the sound tube and dome The ThinTube The ThinTube feeds the amplified sound from the hearing instrument into the ear. It is important that the ThinTube and the dome fit correctly into your ear. If the ThinTube or the dome irritate your ear in any way and prevent you from wearing your hearing instrument, please contact your hearing care professional. You should never attempt to modify the shape of the ThinTube yourself. The ThinTube and the dome should be cleaned regularly.
General warnings • Do not leave your hearing instrument in the sun, near an open fire or in a hot, parked car. • Do not wear your instrument while showering, swimming, in heavy rain or in a moist atmosphere such as steam bath or sauna. • Should your instrument become moist, put it in a dessicator. Your hearing care practitioner will be happy to counsel on this. • Remove your instrument when applying cosmetics, e.g. perfume, aftershave, hair spray, suntan lotion.
Eight steps towards better hearing You need to get used to your new hearing instrument. Sounds seem new and different. That is because you grew accustomed to your diminished hearing. Therefore, familiar sounds seem strange or unnatural at first. Every first-time user of a hearing instrument responds differently to this. Some can wear the new instrument a whole day right from the start while others find it hard to get used to.
3. Have a conversation with a single person Use your instrument in conversation with one person; a family member or a friend. Move to a quiet spot. Explain that you are now wearing a hearing instrument; ask the other person to talk normally. Look at your conversation partner. If your instrument is tuned to your requirements you will be able to communicate better than before. 4. Listen to radio or television Listen to the radio or television. Start with the news, then turn to another program.
Ask others to talk slowly and clearly. Talking louder does not help. If your instrument is equipped with a Dual Microphone System, select the directional listening program. Read more on this on page 15. 6. Visit public buildings Visit public buildings. Try to sit near the speaker; try to be seated in the front rows in a show. Avoid a seat behind a pillar or in an alcove, you will be in a ‘sound shadow.’ In a restaurant, sit with your back towards the wall.
8. Use your instrument all day Using your hearing instrument and practising with it is the best way to learn to hear again. Even if you can hear without an instrument in some cases. Try to wear your instrument all day. In that way you will benefit the most. Of course, a hearing instrument cannot restore natural hearing, but it will help you make the most of your hearing as it is today. Go beyond these eight steps and discover the world of sound around you.
General precautions • Consult a physician if you find a foreign object in your ear canal, if you experience skin irritation or if excessive ear wax accumulates with the use of the hearing instrument. • Different types of radiation, e.g. from NMR or CT scanners, may damage the hearing instrument. Therefore, do not wear the hearing instrument during these or other corresponding scanning procedures.
