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.
