Proper Setup and Use
Table 1 (Cont.) Recommendations for Proper Setup and Use
Adjust To . . .
Terminal 8 Eye level and at the correct distance for proper vision.
Eyes 9 Avoid eye fatigue, which can be caused by glare, image quality,
uncomfortable furniture, eye height, and uncorrected vision. If you
cannot read the screen at different distances, you may need special
glasses. Relax your eyes periodically by looking at distant objects.
Work
Breaks
Take periodic work breaks. Morning, lunch, and afternoon breaks
meet most recommendations. Take advantage of work breaks to
move around and do other movements.
Lighting Avoid direct lighting or sunlight on the screen, which causes glare
and reflections. The VT510 terminal screen has an antiglare
treatment to reduce glare. Place lighting behind or to the side
of your work area, and distribute the lighting evenly on your work
area. Adjust the terminal brightness and the contrast controls as
needed.
Noise Keep background noise at a minimum. Background noise above
65 dBA is tiring. Sound-absorbing materials, such as curtains,
carpeting, and acoustic tile, can help reduce background noise.
Temperature 20°C to 23°C (68°F to 74°F)
Humidity 30% to 70%
Ventilation Provide adequate air ventilation for equipment operation and to
avoid fatigue.
Space
between
terminals
More than 70 cm (28 in) center to center, preferably more than 152
cm (60 in).
Warning
If you experience pain or discomfort during use of the
terminal, then take a substantial break and review the
instructions for posture and work habits. If the pain or
discomfort continues after resuming use of the terminal,
then discontinue use and report the condition to your job
supervisor or physician.
