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.
•
Be aware that you can adapt to higher volume settings
over time, not realizing that the higher volume may be
harmful to your hearing.
•
When using headphones, turn the volume down if you
cannot hear the people speaking near you or if the person
sitting next to you can hear what you are listening to.
•
Do not turn the volume up to block out noisy
surroundings. If you choose to listen to your portable
device in a noisy environment, use noise-cancelling
headphones to block out background environmental
noise. By blocking background environment noise, noise
cancelling headphones should allow you to hear the
music at lower volumes than when using earbuds.
•
Limit the amount of time you listen. As the volume
increases, less time is required before you hearing could
be affected.
•
Avoid using headphones after exposure to extremely loud
noises, such as rock concerts, that might cause
temporary hearing loss. Temporary hearing loss might
cause unsafe volumes to sound normal.
•
Do not listen at any volume that causes you discomfort. If
you experience ringing in your ears, hear muffled speech,
or experience any temporary hearing difficulty after
