General warnings i
Hearing instruments can be dangerous if improperly used.
• Consult a hearing care professional if you discover 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 X-ray, MRI, NMR, CT scans), may damage the instrument. There-
fore, do not wear the instrument during these or other corresponding scanning procedures. Other types
of radiation (burglary alarms, room surveillance systems, radio equipment, mobile telephones, etc) will
not damage the instrument. They could, however, momentarily affect the sound quality or create strange
sounds from the instruments.

certified for hearing instrument use.

or to the hearing of the other individual.

their safety.
