WARNING | If your PC is multimedia or if you add a sound card to your PC, always turn the |
| volume down before connecting headphones or speakers, to avoid discomfort |
| from unexpected noise or static. Listening to loud sounds for prolonged |
| periods of time may permanently damage your hearing. Before putting on |
| headphones, place them around your neck and turn the volume down. When |
| you put on the headphones, slowly increase the volume until you find a |
| comfortable listening level. when you can hear comfortably and clearly, |
| without distortion, leave the volume control in that position. |

General | • Work Surface Height - Adjust either your seat height, work surface or |
| both, to position the work surface at approximately elbow height. |
| • Work Surface Arrangement - Make sure frequently used equipment is |
| within easy reach. For example, if you are primarily using the keyboard, |
| place it directly in front of you, not to the side. If you are primarily using the |
| mouse, place it in front of your hand or arm. If you are using both a mouse |
| and keyboard, place them both at the same work surface height and close |
| together. If a palm rest is used, the height should be flush with the front |
| edge of the keyboard. Other items, such as your telephone or notepad, also |
| should be considered. |
| • Monitor - Place your monitor so that the top of the screen is at, or slightly |
| below, eye level (up to 15 degrees). |
| • Head - Do not tilt your head forward by more than 15 degrees, and try not |
| to turn your head toward the side. |
