device. Rough handling can break internal
circuit boards.
Paint
Do not paint the mobile device. Paint can
clog the device’s moving parts or
ventilation openings and prevent proper
operation.
Responsible Listening
Caution! Avoid potential hearing loss.
Damage to hearing occurs when a person is
exposed to loud sounds over time. The risk of
hearing loss increases as sound is played
louder and for longer durations. Prolonged
exposure to loud sounds (including music) is
the most common cause of preventable
hearing loss. Some scientific research suggests
that using portable audio devices, such as
portable music players and cell phones, at high
volume settings for long durations may lead to
permanent noise-induced hearing loss.
This includes the use of headphones (including
headsets, earbuds, and Bluetooth
®
or other
wireless devices). Exposure to very loud sound
has also been associated in some studies with
tinnitus (a ringing in the ear), hypersensitivity to
sound, and distorted hearing. Individual
susceptibility to noise-induced hearing loss and
potential hearing problem varies. Additionally,
the amount of sound produced by a portable
audio device varies depending on the nature of
