Adjust | To | . . . |
|
| |
| 6 Keep your upper arms straight down at your sides, elbows | |
|
| close to your sides to support your arm weight. Forearms |
|
| should be at a 70° to 90° angle. |
Head | 7 | Avoid neck strain. Your head should incline downward, but |
|
| no more than 15° to 20°. |
Terminal | 8 Keep eye level and 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 |
| Take periodic work breaks. Morning, lunch, and afternoon |
Breaks |
| 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 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. |
|
| 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 |
| More than 70 cm (28 in) center to center, preferably more |
between |
| than 152 cm (60 in). |
