Listening Safely
To protect your hearing, follow these
guidelines when you use headphones.
• Set the volume to its lowest setting
before you begin listening. After you
begin listening, adjust the volume to
a comfortable listening level.
• Do not listen at extremely high vol-
ume levels. Extended high-volume
listening can lead to permanent
hearing loss.
• Once you set the volume, do not
increase it. Over time your ears
adapt to the listening level, so a vol-
ume level that does not cause dis-
comfort might still damage your
hearing.
