Epson Endeavor 468C - Manual (Page 55)

Work in a relaxed, natural, upright position and let the chair
support you. Your elbows should be near your body and level
with or slightly lower than the keyboard so your hands rest
lightly on the keys. To help you keep your wrists straight, the
slope of the keyboard should be no more than 25 degrees. Try
not to hit the keys too hard; using too much force creates
tension in your hands. Also leave enough room on your work
surface so you can freely move the mouse (or other pointing
device), and be sure to rest your hands occasionally.
Varying Your Posture and Movements
While sitting at the computer, try to vary your posture and
movements. Your seat and backrest should be wide enough
and there should be enough room under your desk so that you
can sit in a variety of positions throughout the day.
Be sure to occasionally stop working at your computer and
perform other tasks. Also take periodic breaks; stand up,
stretch, and move around.
Lighting the Room
While it is important to have adequate lighting in your work
area, make sure it is not too bright. When a light source is very
bright, your eyes get tired by having to continually readjust
between the relative dimness of the screen and the bright
surroundings. It is best to control the amount of daylight that
enters the room and keep bright light sources out of your field
of vision when you are looking at the screen.
