Listening Safely

To protect your hearing, follow these guidelines when you use
headphones.
• Set the volume to the lowest setting before you begin lis-
tening. 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 permanent 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.
