Chapter 8 Safety and Handling 54
Hearing loss Listening to sound at high volumes may damage your hearing. To prevent possible
hearing damage, do not listen at high volume levels for long periods. Background noise, as
well as continued exposure to high volume levels, can make sounds seem quieter than they
actually are. The Apple Earphones with Remote and Mic sold with iPhone 4S and later in China
(identiable by dark insulating rings on the plug) are designed to comply with Chinese standards
and are not compatible with iPod classic. Use only compatible earbuds or headphones with your
device. 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 iPod classic, see Setting the maximum volume limit on page 30.
