Before Use
❑
Position of your computer – Place the computer directly in front of you (1). Keep your forearms horizontal (2), with your
wrists in a neutral, comfortable position (3) while using the keyboard, touch pad, or external mouse. 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.
❑
Viewing angle of the computer's display – Use the display's tilting feature to find the best position. 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.
❑
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.
❑
Positioning an external display – When using an external display, set the display at a comfortable viewing distance.
Make sure the display screen is at eye level or slightly lower when you are sitting in front of the monitor.
