Page 30: Instrument Care
Instrument care Healthy ears produce a waxy substance that can clog your hearing instruments. Please follow these cleaning instructions to prevent wax build-up and ensure optimal performance of your instruments. Every night • Check your instruments for ear wax and wipe them clean with a cloth or tissue. • If necessary, use the cleaning tool to remove wax from the canal and vent openings on your earmold. • Open the battery drawer fully to allow air to circulate. • A dry storage kit is recommended to remove any moisture that may have accumulated in the instrument. - Page 31 If you have an earmold You should wash your earmolds regularly. The hearing instrument itself must never be washed or allowed to get wet! Bernafon Veras IFU micro BTE • Handle your instruments over a soft surface to avoid damage in case you drop them. VR_ILU_CleaningEarmoldAttachMicroBTE_BW_HI • Disconnect the earmold from the hearing instrument by grasping the end of the hook firmly with one hand and grasping the tub- ing firmly with the other hand. • Pull the tubing away from the earhook. • Gently clean the earmold in warm soapy water. • Rinse the earmold and allow it to dry completely. • Use an air puffer to remove any remaining moisture in the tubing. • When re-attaching the earmold to the instrument, it is important to position it correctly, as shown above.
- Page 32 Cleaning the Spira Flex thin sound tube system If you have the sound tube system, make sure that the tube and dome are kept free of ear wax at all times. • Grasp the adapter firmly and disconnect the sound tube from the instrument by pulling it off. • Use a soft dry cloth or tissue to clean the outside of the sound tube and dome. • To remove wax from the sound tube, insert the cleaning wire at the c onnector end. Push the cleaning wire all the way into the sound tube until it comes out through the dome. • Pull the cleaning wire out through the dome and discard it. • Reattach the sound tube connector to the adapter. Important: To avoid blocking the sound tube, do not use water to clean it.
- Page 33 Exchanging the dome The dome should be changed regularly. The fre- quency of dome changes will depend on how fast ear wax builds up on the dome. Spare domes can be obtained from your hearing care professional. • Remove the old dome by pulling it off the end of the sound tube. • With clean fingers, push a new dome as far as possible onto the sound tube. When attached correctly, the dome should touch the plastic ring around the sound tube. Warning If the dome is not securely attached to the sound tube, it could fall off in your ear canal. If this happens, please see your medical practitioner.
- Page 34 Exchanging the Spira Flex sound tube If the sound tube becomes discolored, stiff or brittle, it should be replaced. • Hold the instrument by the adapter and grasp the tube close to the connector. • Pull firmly to remove the old tube. • Attach the new sound tube by pushing it firmly Bernafon Veras IFU micro BTE into the connector.

Page 36: Using Your Hearing Instruments
Using your hearing instruments Hearing instruments do not restore perfect hear- ing. They make sounds louder and help you make the most of the hearing you have. While some immediate benefit is usually noticed, it often takes several weeks for your brain to adapt to the new sounds. The following tips will help you learn to use your instruments. If you have trouble adjusting, consult your hearing care professional. Getting started • Wear your instruments at home in a quiet environment. Have a conversation with one person or listen to a news program on TV. • You will benefit most if you wear your instru- ments all day long. Increase the time each day until you are comfortable wearing them for several hours at a time. - Page 37 • You may notice that your own voice sounds louder. If the voices of others are at a comfort- able level, try speaking at a lower volume. • Sounds like footsteps, chirping birds, rustling paper, etc. may seem quite loud at first because you probably haven’t heard them for awhile. They will soon fade to the background. Dining out • Start with a quiet restaurant (no music or enter- tainment). • Request a table away from the kitchen and other noisy areas. • Conversation will be easier in a smaller group. In the car • Sit with your better ear toward the center of the car. • Turn off the radio. • Keep windows closed to minimize traffic, road and wind noise.
- Page 38 Attending theatre, concerts, lectures, etc. • Ask if there is a loop system available. If not, request to be seated near the front. • Try to sit with your better ear closer to the sound source. • Become familiar with the program in advance to make it easier to follow. At work • Inform your co-workers about your hearing loss. • If you hear only part of a conversation, repeat what you have heard and ask for the missing information.
-
Page 39: Using The Telephone
Using the telephone • Hold the receiver close to the microphone inlet of your hearing instrument. If this causes whistling, move the receiver away a small distance. • If voices over the telephone are too soft or background noise is a problem, use the telecoil (be aware that not all phones are telecoil compatible). • When using the telecoil, hold the phone behind the ear, next to your hearing instrument for b etter reception. • Mobile phones may cause interference with the telecoil. In this case, the microphone mode will give a better result. • Before purchasing a mobile phone, test it with your hearing instrument. • People with a greater degree of hearing loss may need a volume control on the telephone. -
Page 40: Environmental Protection
Environmental protection Your hearing instruments contain electronic components subject to the Directive 2002/96/EC on waste electrical and electronic equipment. Help to protect the environment by not disposing of your hearing instruments or batteries with your unsorted household waste. Please recycle your hearing instruments and batteries according to your local regulations or return them to your hear- ing care professional for disposal. -
Page 41: Product Approval, Markings And Compliance
Product approval, markings and compliance All Bernafon Chronos hearing instrument models comply with international standards concerning electromagnetic compatibility. Due to the limited size available on the instruments all relevant approval markings are found in this document. Electromagnetic interference Your hearing instrument has been thoroughly tested for electromagnetic interference. However, some products may emit electromagnetic energy causing unforeseen interference with hearing instruments. Examples include induction cooking appliances, shop alarm systems, mobile phones, fax machines, personal computers, X-rays, CT scans, etc. Even though your hearing instruments are de- signed to comply with the most stringent interna- tional standards of electromagnetic compatibility, they may emit electromagnetic energy that can cause interference with other devices. - Page 42 Your hearing instruments may contain a radio transmitter using short range magnetic induction technology working at 3.84 MHz. The magnetic field strength of the transmitter is < – 42 dBμA/m @ 10 The electromagnetic emission from the radio system is well below international limits for human exposure. By comparison, the electromagnetic energy of the hearing instrument is lower than that generated by household items such as halogen lamps, computer monitors, dishwashers etc.

Page 43: Cell Phone And Hearing Instrument Compatibility
Cell phone and hearing instrument compatibility Some hearing instrument users have reported a buzzing sound in their instruments when they are using cell phones, indicating that the cell phone and hearing instrument may not be compatible. 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 (ANSI C63.19-2006 American National Standard Methods of Measurement of Compatibility between Wireless Communication Devices and Hearing Aids). For example, the sum of a hearing aid with a rating of 2 (M2/T2) and a telephone with a rating of 3 (M3/T3) would result in a combined rating of 5. According to the standard, any combined rating that equals at least 5 would provide “normal use”; a combined rating of 6 or greater would indicate “excellent performance.”... - Page 44 The immunity of your Chronos hearing instrument is at least M2/T2. The equipment performance measurements, categories and system classifica- tions are based upon the best information available but Bernafon cannot guarantee that all users will be satisfied.

Page 50: General Warnings And Safety Guidelines
General warnings and safety guidelines Hearing instruments and batteries can be danger- ous if swallowed or improperly used. Such actions can result in severe injury, permanent hearing loss or even fatality. Familiarize yourself completely with the following general warnings before using your hearing instru- ments. • Hearing instruments should be used only as d irected and adjusted by your trained hearing care professional. Misuse or improper adjust- ments can result in sudden and permanent hearing loss. • Hearing aids will not restore normal hearing or prevent hearing loss resulting from organic conditions. • Never allow others to wear your hearing instru- ments, because they are adjusted for your hear- ing requirements and may permanently damage another person’s hearing. - Page 51 • A slap to your ear while wearing the instrument could be harmful. Avoid wearing your hearing instrument while playing contact sports (e.g. rugby, football etc.). • Be aware that use of a hearing instrument may cause excess ear wax to build up in the ear canal which may require removal by a trained medical professional. • In rare cases, a hearing aid or earmold may cause a discharge from the ear or allergic reaction. See a physician immediately an allergic reaction. if these conditions occur. • An earmold is a custom-made product. If you experience discomfort or irritation of your ear, please see your hearing care professional imme- diately for modification of the earmold. • Hearing instruments, their parts and batteries should be kept out of reach of infants, children and anyone who might swallow these items or otherwise cause themselves injury. • Discard batteries and keep them out of sight of infants, small children, persons of mental incapacity or pets.
- Page 52 • Clean your hearing instruments and their parts on a regular basis as recommended. Micro- organisms from unclean instruments may cause skin irritations. • Be careful with leaking battery liquid, as it is a hazardous substance. • Never try to recharge non-rechargeable batteries. • Never change the battery or adjust the controls of the hearing instrument in front of infants, small children and persons of mental incapacity. • Never put your hearing instrument or batteries in your mouth, they could easily be swallowed. • Keep batteries away from medications. Batteries are easily mistaken for pills. • In case a battery or hearing instrument is swallowed, see a doctor immediately. • Be aware of the possibility that your instruments may stop functioning without notice. Keep this in mind while you circulate in traffic or otherwise depend on warning sounds.
- Page 53 • Traffic or other warning sounds may also be r educed in level by a directional microphone when these sounds are coming from behind you. • Never insert cleaning tools into the sound outlet or microphone inlet. This could damage the hearing instruments. Warning to hearing care professional and user Special care should be taken when fitting and u sing a hearing instrument with maximum sound pressure capability in excess of a maxi- mum of 132 dB SPL (IEC 60318-4) since there may be a risk of i mpairing the remaining hearing of the hearing instrument user.
