If the touch-sensitive sensor does not make contact with your ear, the earbud may not
work. Use the ear tips that fit your ears if you do not hear a sound informing you that the
earbud is detected.
If the earbuds are not positioned correctly in your ears, features like calling through the
earbuds may not work. Use a pair of ear tips that fit your ears and wear the earbuds
properly.
Follow all posted warnings and directions from authorised personnel in areas where the
use of wireless devices is restricted, such as airplanes and hospitals.
