• Wearing a hearing instrument might cause an increased pro duction of earwax . In
rare cases, the anti-allergenic materials may cause skin irritation . If so, or if in doubt,
consult your physician or ENT consultant .
• 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 hear-
ing instrument . Therefore, do not wear the hearing instrument during these or other
corresponding scanning procedures . Other types of radiation (burglary alarms, room
surveillance systems, radio equipment, mobile telephones, etc) contain less energy
and will not damage the hearing instrument . They could however momentarily affect
the sound quality or create strange sounds from the hearing instruments .
• Warning: Do not wear the hearing instrument in mines or other explosive areas,
unless those areas are certified for hearing instrument use .
Intended Use
Generic air-conduction hearing instruments are wearable sound-amplifying devices
intended to compensate for impaired hearing . The fundamental operating principle of
hearing instruments is to receive, amplify, and transfer sound to the ear drum of a hear-
ing impaired person .
