Sound and hearing
Caution! Avoid potential hearing loss by not
exposing yourself to loud sounds for a prolonged
period of time. The risk of hearing loss increases
as sound is played louder and for longer
durations. The amount of sound produced by
a portable audio device (including headsets,
earbuds, and Bluetooth® or other wireless
devices) varies depending on the nature
of the sound, the device settings, and the
headphones that are used. As a result, there is
no single volume setting that is appropriate for
everyone or for every combination of sound,
settings and equipment.
Restricting children's access to your mobile
device
Your device is not a toy. Do not allow children to
play with it because they could hurt themselves
and others, damage the device, or make calls that
increase your mobile device bill.
Keep the device and all its parts and accessories
out of the reach of small children.
