Before Use
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 (1). Keep your forearms horizontal (2), with your
wrists in a neutral, comfortable position (3) while using the keyboard, pointing device, or external mouse. Let your upper
arms hang naturally at your sides. Have breaks during sessions with 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.
