Lenovo 3000Y310 UG.book Page 21 Friday, September 14, 2007 4:24 PM Getting Started General Posture: Below are some general recommendations for assuming a healthy working posture. It is best to periodically make minor modifications in your working posture to deter the onset of discomfort caused by long periods of working in the same position. Frequent, short breaks from your work will also help to prevent any minor discomfort associated with your working posture. Display: Position the display to maintain a comfortable viewing distance of 510-760 mm (20-30 in). Avoid glare or reflections on the display from overhead lighting or outside sources of light. Keep the display screen clean and set the brightness to levels that enable you to see the screen clearly. Press Fn + up/down arrow key to adjust display brightness. Head Position: Keep your head and neck in a comfortable and neutral (vertical, or upright) position. Chair: Use a chair that gives you good back support and seat height adjustment. Use chair adjustments to best suit your desired posture. Arm and Hand Position: If available, utilize chair arm rests or an area on your working surface to provide weight support for your arms. Keep your forearms, wrists, and hands in a relaxed and neutral (horizontal) position. Type with a soft touch without pounding the keys. Leg Position: Keep your thighs parallel to the floor and your feet flat on the floor or on a footrest. What If You Are Traveling? It may not be possible to observe the best ergonomic practices when you are using your computer while on the move or in a casual setting. Regardless of the setting, try to observe as many of the tips as possible. Sitting properly and using adequate lighting, for example, will help you maintain desirable levels of comfort and performance. Questions about Vision? Your computer's visual display screen is designed to meet the highest standards and to provide you with clear, crisp images and large, bright displays that are easy to see, yet easy on the eyes. Of course, any concentrated and sustained visual activity can be tiring. If you have questions on eye fatigue or visual discomfort, consult a vision care specialist for advice. Chapter 3.
