Ergonomic Considerations; Notes On Setup - Sony VAIO PCG-R505AFE Safety Information Manual

Ergonomic Considerations

Your computer is a portable device and can be used in a variety of environments. Whenever possible,
you should apply the following ergonomic considerations for both stationary and portable
environments.
❑
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
viewing angle. Also try adjusting the brightness setting of the display. Following these
suggestions can reduce eye strain and muscle fatigue.
❑
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.
