VAIO Digital Studio Computer Quick Start To Choose an Ergonomic Location Before you get started, find the best location for your new computer. Planning your work space ❑ Stable work surface - Use a stable work surface large enough to support the computer and other peripheral equipment. ❑ Ventilation - Leave at least eight inches of space on the left and back sides of your computer to enable proper ventilation. ❑ Placement of the keyboard, mouse, and other input devices - Place your keyboard, mouse, and other input devices so that your arms and hands are in a relaxed, comfortable position. The keyboard should be directly in front of you. Adjust the level of the keyboard so that your lower arms are parallel to the floor. Keep your wrists in a relaxed position when you are using the keyboard-not angled up or down. Use the palmrest only briefly, for resting. While typing, never use the palmrest or rest your hands on the table. Position the mouse at the same level as the keyboard. Hold the mouse with a relaxed hand, and use your whole arm to move it. Take breaks during sessions with your computer. Excessive use of the mouse or a joystick may strain muscles or tendons. ❑ Furniture and posture - Sit in a chair with good back support and armrests. Adjust the level of the chair so your feet are flat on the floor. A footrest may make you more comfortable. Sit with relaxed, upright posture-avoid slouching forward or leaning far backward. ❑ Viewing angle of the display - Position the display 18 to 26 inches directly in front of you, with the top of the screen at or a little below eye level. Use the display's tilting feature to find the best position. You can reduce eye strain and muscle fatigue by placing the display in the proper position. ❑ Lighting - Choose a location where windows and lights do not create glare and reflection on the display. Use indirect lighting to avoid bright spots on the display. You can also purchase accessories for your display that help reduce glare. Proper lighting adds to your comfort and work effectiveness. 10
