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, s o a volume level that does not cause discomfort might still damage your hearing.
