Listening Safely

To protect your hearing, follow these guidelines when you use an earphone or headphones.

•Set OFF/VOLUME to the lowest setting before you begin listening. After you put on the earphone or headphones, adjust OFF/VOLUME to a comfortable level.

•Do not listen at extremely high volume levels. Extended high-vol- ume listening can lead to perma- nent hearing loss.

•Once you set OFF/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.
