Infrequent use of a hearing aid does not permit a user to attain full bene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.The hearing aid is suitable for the home healthcare environment and due to their portability it may happen that it is used in professional healthcare facility environment like physician oces, dental oces etc.18. Important safety information51 The Phonak rechargeable hearing aids and the Phonak Power Pack contain lithium-ion batteries that can be taken onto airplanes as carry-on luggage. The Power Pack cannot be placed in the checked-in baggage and can only be placed in the carry-on luggage. 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. Changes or modications  to the hearing aid that were not explicitly approved by Sonova AG are not permitted. Such changes may damage your ear or the hearing aid. Do not use the hearing aids and charging accessories in explosive areas (mines or industrial areas with danger of explosions, oxygen rich environments or areas 18.1 Hazard warnings52where ammable anesthetics are handled) or where electronic equipment is prohibited. If you feel pain in or behind your ear, if it is inamed or if skin irritation and accelerated accumulations of earwax occur, please check with your hearing care professional or physician. In very rare cases, the dome can remain in your ear canal when removing the hearing tube from the ear. In the unlikely case that the dome does get stuck in your ear canal, it is strongly recommended to see a physician for safe removal. 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. 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, individuals with cognitive impairment and pets. If swallowed, consult a physician or hospital immediately.
53 Keep the Charger Case out of reach of children, individuals with cognitive impairment and pets. If  the drying capsule is swallowed, consult  a physician or  hospital immediately. Only authorized personnel are allowed to open the Power Pack due to possible electrical hazard.  Do not make a wire connection from your hearing aid to any external audio sources like radio etc. That could cause injuries on your body (electric shock). Do not cover the whole Charger Case or Mini Charger while charging, e.g. with a cloth etc.   The following is only applicable for persons with active implantable medical devices (i.e. pacemakers, de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.54     • Keep magnets (i.e. EasyPhone magnet, etc.)  at least 15 cm (6 inches) away from the active implant.     • If using a Phonak wireless accessory, consult the chapter “Important safety information” in your wireless accessory  user guide. 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.  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.    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 aid(s), including cables specied by the manufacturer. 55  Hearing aids should not be tted with domes / wax protection systems when used by clients with perforated eardrums, inamed ear canals or otherwise exposed middle ear cavities. In these cases, we recommend the use of a classic earmold.  In the unlikely case that any part of this product should remain in the ear canal, it is strongly recommended to see a physician for safe removal.  Otherwise, degradation of the performance of this equipment could result. The USB port of the  charger is to be used for the described purpose only. For charger, use only EN60950 and/or  EN60601-1 certied  equipment with a output rating of 5 VDC.  Min. 500 mA. Do not insert the adapter of the power supply alone into electrical outlets  because this could result in an electric shock.56 Phonak 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 aid in water! Phonak 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 aid before these activities, as the hearing aid contains sensitive electronic parts.18.2 Information on product safety 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 (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.
57  Do not drop your hearing aid! Dropping onto a hard surface can damage your hearing aid.  Store your hearing aid in the charger if you are not using it for a long period of time. 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.58 The hearing aids have to be dry before charging. Otherwise the charging reliability cannot be guaranteed. Only use approved chargers and Power Pack described in this user guide for charging your hearing aid(s), otherwise the devices may be damaged.Both your hearing aid(s) and Power Pack contain lithium-ion batteries with a Watt hour rating <20 Wh which have been tested according to UN 38.3 of the “UN Manual of Tests and Criteria” and should be shipped in accordance with all the rules and regulations on the safe shipment of lithium-ion batteries.59Notes029-0477-02/V1.00/2017-01/FO © Sonova AG   All rights reservedManufacturer:Sonova AGLaubisrütistrasse 28CH-8712 StäfaSwitzerlandwww.phonak.comYour hearing care professional:
