6. Hearing aids should be used only as prescribed by your hearing care professional. Incorrect use
may result in sudden and permanent hearing loss.
7. Warning to hearing care professionals: Special care should be exercised in selecting and fitting
hearing aids with maximum sound pressure level that exceeds 132dB SPL with an IEC
60711:1981 occluded ear simulator. There may be a risk of impairment of the remaining hearing.
8. Turn off your wireless functionality by using the flight mode in areas where radio frequency
emission is prohibited.
9. If a hearing aid is broken, do not use it.
10. A power hearing aid can produce very loud sound to compensate for a severe or profound hearing
loss. There is therefore a risk of further impairing the remaining hearing.
11. External devices connected to the electrical input must be safe according to the requirements of
IEC 60601-1, IEC 60065, EN/IEC 62368-1, or IEC 60950-1, as appropriate (wired connection, for
example HI-PRO, SpeedLink).
NOTE: For use of wireless functionality, only use supported wireless accessories. For further
guidance regarding e.g. pairing, please refer to the user guide of the relevant wireless
accessory.
