Welcome

Ergonomic considerations

❑
You will be using your notebook as a portable device in a variety of environments. Whenever possible,
you should attempt to take account of the following ergonomic considerations to both stationary and
portable environments:
❑
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,
touchpad, 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 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.
