Before Use
Ergonomic Considerations
You will be using your computer 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, touch pad, 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.
