Notes:
Listening Safely
To protect your hearing, follow these guidelines when you use head- phones.
•Do not listen at extremely high volume levels. Extended high- volume listening can lead to per- manent hearing loss.
•Set the volume to the lowest set- ting before you begin listening. After you begin listening, adjust the volume to a comfortable level.
•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.
