Contraindications : General clinical contra-indications for the use of hearing aids and Tinnitus software feature are:

• Hearing loss is not in the fitting range of the hearing aid (i.e. gain, frequency response)

• Acute tinnitus

• Deformity of the ear (i.e. closed ear canal)

• Neural hearing loss
  The primary criteria for the referral of a patient for a medical or other specialist opinion and / or treatment are as follows:

• Abnormal appearance of the eardrum and ear canal such as:

• Inflammation of the external auditory canal

• Perforated eardrum

• Other abnormalities which the hearing care professional believes are of medical concern

• Tinnitus feature : Tinnitus feature provides supplementary noise stimulation which can help defocus the user`s attention from their tinnitus.
• Side effects : Physiological side-effects of hearing aids like tinnitus, dizziness, wax build up, too much pressure, sweating or moisture, blisters, itching and/or rashes, plugged or fullness and their consequences like headache and/ or ear pain, may be resolved or reduced by your hearing care professional.
• Conventional hearing aids have the potential to expose patients to higher levels of sound exposure, which might result in threshold shifts in the frequency range affected by acoustic trauma.
• Hazard warnings
• Your Virto P-312 hearing aids operate between 2.4 GHz­2.48 GHz frequency range.
• When flying please check if flight operator requires devices to be switched into flight mode, see chapter 14.
• Changes or modifications 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 in explosive areas (mines or industrial areas with danger of explosions, oxygen-rich environments or areas where flammable
• anesthetics are handled).
• This device is not ATEX certified.
• WARNING: Device batteries are hazardous and can cause serious injuries if they are swallowed or placed inside any part of the body, whether the
• battery is used or new!
• Keep out of the reach of children, individuals with cognitive impairment, or pets.
• If you suspect that a battery was swallowed or placed inside any part of the body, immediately consult your physician without any delay!.
• If you feel pain in or behind your ear, if it is inflamed or if skin irritation and accelerated accumulations of earwax occur, please check with your hearing care professional or physician.
• Titanium shells of custom hearing aids and earpieces can contain small quantities of acrylates from adhesives. People who are sensitive to such substances may potentially experience an allergic skin reaction. Please stop using the device immediately if such a reaction occurs and check with your hearing care professional or physician.
• In very rare cases if not securely attached, a cerumen stop can remain in your ear canal when removing the hearing aid from the ear. In the unlikely case that such part gets 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. The hearing aid is a small device and contains small parts. Do not leave children, individuals with cognitive impairment or pets unsupervised with this hearing aid. If swallowed, consult a physician or hospital immediately as the hearing aid or its parts can be choking or poisonous hazard.
• The following is only applicable for persons with active implantable medical devices (i.e. pacemakers, defibrillators, etc.) Keep the wireless device 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 the interference can also be caused by powerlines, electrostatic discharge, airport metal detectors etc. Keep magnets (e.e battery handling tool, EasyPhone magnet, etc.) at least 15 cm (6 inches) away from the active implant.
• Use of accessories, transducers and cables other than those specified 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.
• Virto P-312 only: 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 aids, including cables specified by the manufacturer. Otherwise, degradation of the performance of this equipment could result.
• Avoid strong physical impacts to the ear when wearing in-theear hearing aids. The stability of in-the-ear shells is designed for normal use. A strong physical impact to the ear (e.g. during sports) may cause the in-the-ear shell to break. This may lead to perforation of the ear canal or ear drum.
• After mechanical stress or shock to the hearing aid, please ensure that the hearing aid shell is intact before placing it in the ear.
• 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.
• 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.
• Patients implanted with magnetic externally programmable CSF shunt valves may have a risk of experiencing an unintended change in their valve setting when exposed to strong magnetic fields. The receiver (loudspeaker) of hearing aids, the Lyric SoundLync, the Lyric programming wand and the
• MiniControl contain static magnets. Keep a distance of 2 inches (approx. 5 cm) or more between the magnets and the site of the implanted shunt valve.
• The majority of hearing aid users have a hearing loss for which a deterioration in hearing is not to be expected with regular use of a hearing aid in everyday situations. Only a small group of hearing aid wearers with hearing loss, may be at risk of deterioration in hearing after a long period of use.

Information on product safety

• Phonak hearing aids are water resistant and not waterproof.
• They are designed to withstand normal activities and occasional accidental exposure to extreme conditions.

• Remove the battery if you are not using your hearing aid for a long period of time.
• Special medical or dental examination including radiation described below, may adversely affect 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 fields. 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 affect the hearing aids.
• Do not use your hearing aid in areas where electronic equipment is prohibited.
• Do not kink or buckle the removal handle. Repeated stress to the removal handle may cause it to break. In case of a broken removal handle the battery door may exceptionally be used to carefully pull the hearing aid out of the ear canal.
