Before Use > Ergonomic Considerations n 8 N Ergonomic Considerations Whenever possible, you should attempt to take account of the following ergonomic considerations: ❑ ❑ Position of your computer – Place the display directly in front of you. Keep your forearms horizontal, with your wrists in a neutral, comfortable position while using the keyboard or the pointing device. Let your upper arms hang naturally at your sides. Take frequent breaks while using your computer. Excessive use of the computer may strain eyes, muscles, or tendons. Furniture and posture – Sit in a chair with good back support. Adjust the level of the chair so your feet are flat on the floor. A footrest may make you more comfortable. Sit in a relaxed, upright posture and avoid slouching forward or leaning far backwards.

You can reduce eye strain and muscle fatigue by adjusting the tilt of the display to the proper position. Adjust the brightness level of the display as well. ✍ You can tilt the computer display within the range from about 8 to 30 degrees. ❑ ❑ ! While adjusting the viewing angle, do not exert excessive pressure on your computer to eliminate a risk of mechanical damage. Lighting – Choose a location where windows and lights do not cause glare and reflection on the display. Use indirect lighting to avoid bright spots on the display. Proper lighting adds to your comfort and work efficiency. Ventilation – Make sure you leave at least 10 cm of space behind and at least 20 cm of space on each side of the main unit.
