Microwaves
Do not try to dry your mobile device in a
microwave oven. Doing so may cause a fire
or explosion.
Dust and dirt
Do not expose your mobile device to dust,
dirt, or sand.
Cleaning solutions
Do not use harsh chemicals, cleaning
solvents, or strong detergents to clean the
mobile device. Wipe it with a soft cloth
slightly dampened in a mild soap-and-water
solution.
Shock or vibration
Do not drop, knock, or shake the mobile
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
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.
You should follow some common sense
recommendations when using any portable
audio device:
• Always turn the volume down before plugging the
earphones into an audio source.
• Set the volume in a quiet environment and select
the lowest volume at which you can hear
adequately.
