Hearing loss Listening to sound at high volumes may damage your hearing. Background noise,
as well as continued exposure to high volume levels, can make sounds seem quieter than they
actually are. Turn on the audio and check the volume before inserting anything in your ear. For
more information about hearing loss, see www.apple.com/sound. For information about how to
set a maximum volume limit on iPad, see Music settings on page 57.
WARNING: To prevent possible hearing damage, do not listen at high volume levels for
long periods.
