Preparation
• Once you set the volume, do not
increase it. Over time, your ears
adapt to the volume level, so a vol-
ume level that does not cause dis-
comfort might still damage your
hearing.
Traffic Safety
Do not wear an earphone while operating
a motor vehicle or riding a bicycle. This
can create a traffic hazard and could be il-
legal in some areas.
Even though some earphones let you
hear some outside sounds when listening
at normal volume levels, they still can
present a traffic hazard.
