Do not turn your phone on or off when putting it to your ear.
●
Use accessories, such as earphones and headsets, with caution.
Ensure that cables are tucked away safely and do not touch the
antenna unnecessarily.
Caution: Avoid potential hearing loss.
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 cellular telephones, 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), hypersensitivityto sound
and distorted hearing. Individual susceptibility to noise-induced
hearing loss and other potential hearing problems varies.
The amount of sound produced by a portable audio device varies
depending on the nature of the sound, the device, the device
settings and the headphones. You should follow some
commonsense recommendations when using any portable audio
device:
●
Set the volume in a quiet environment and select the lowest
volume at which you can hear adequately.
●
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.
