Notes on Use
You will be using your notebook as a portable device in a variety of
environments. Whenever possible, you should comply with ergonomic guidelines
in both stationary and portable environments.
Ergonomic Guidelines
❑ Position of your computer — Place the computer directly in front of you as
you work. Keep your forearms horizontal, with your wrists in a neutral,
comfortable position while using the keyboard, touchpad, or external mouse.
Let your upper arms hang naturally at your sides. Take 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 and
armrests. 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 backward.
❑ 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 setting of the display also.
❑ 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.
❑ Placement of 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.
