• Your hearing aids are tuned to your hearing. Do not allow others to use your hearing aids as this can
damage their hearing.
• When using wireless functions, your hearing aid uses low-powered digitally coded transmissions to
communicate with other wireless devices. It is possible, but not likely, that other electronic devices will
be affected. If this happens, move the hearing aid away from the affected electronic device.
• Turn off hearing aid wireless functionality when this is required.
For hearing care professionals
WARNING: The developed sound pressure level in the ears of children can be substantially higher
than in average adults. It is recommended to perform an RECD measurement in order to ensure
the correct target for the fitted OSPL90.
CAUTION: Do not change the outer casing or any parts of a hearing aid unless appropriately
protected against ESD.
