Toshiba V1100 - Manual (Page 23)

If you are using a conventional chair:
□ Your knees should be slightly higher than your hips. If necessary, use
a footrest to raise the level of your knees and ease the pressure on
the back of your thighs.
□ Adjust the back of your chair so that it supports the lower curve of your
spine. If necessary, use a cushion to provide extra back support. Lower­
back-support cushions are available at many office supply stores.
□ Sit with your back straight so that your knees, hips, and elbows form
approximately 90-degree angles when you work. Do not slump
forward or lean back too far.
Lighting
Proper lighting can improve the visibility of the display and reduce
eyestrain.
□ Position the monitor so that sunlight or bright indoor light ing does
not reflect off the screen. Use tinted windows or shades to reduce
glare.
□ Avoid placing the monitor in front of a bright light that could shine
directly in your eyes.
□ If possible, use soft, indirect lighting in the computer work area.
Arms and wrists
To protect your arms and wrists:
□ Avoid bending, arching, or twisting your wrists. Keep them in a
relaxed, neutral position while typing.
□ Exercise your hands, wrists, and arms to improve circulation.
Work habits
The key to avoiding discomfort or injury from strain is to vary your
activities. If possible, schedule a variety of tasks into your working day.
Finding ways to break up the routine can reduce stress and improve your
efficiency. Some ways to improve your work situation are:
□ Take frequent breaks to change position, stretch your mus cles, and
relieve your eyes. A break of two or three minutes every half hour is
more effective than a long break after several hours.
□ Avoid performing repetitive activities for long periods. Intersperse
such activities with other tasks.
□ Focusing your eyes on the computer screen for long peri ods can
cause eyestrain. Look away from the computer frequently and focus
your eyes on a distant object for at least thirty seconds.
