Listening Safely
To protect your hearing, follow these
guidelines when you use headphones.
• Set 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 highvolume listening can lead to permanent hearing loss.
• Once you set the volume, do not
increase it. Over time, your ears
adapt to the vol ume level, so a
volume level that does not
cause discomfort might still
damage your hearing.
