Listening Safely
To protect your hearing, follow these guidelines
when you use an earphone.
• Rotate the volume to the lowest setting before
you begin listening. After you begin listening,
adjust the volume to a comfortable level.
• Do not listen at extremely high volume levels.
Extended high-volume listening can lead to per-
manent hearing loss.
• Once you set the volume, do not increase it.
Over time, your ears adapt to the volume level,
so a volume level that does not cause discomfort
might still damage your hearing.
Traffic Safety
Do not wear an earphone while operating a motor ve-
hicle or riding a bicycle. This can create a traffic haz-
ard and could be illegal in some areas.
Even though some headphones let you hear some
outside sounds when listening at normal volume lev-
els, they still can present a traffic hazard.
