Ergonomic instructions
CAUTION: Improper or prolonged keyboard use may result in injury.
CAUTION: Viewing the monitor screen for extended periods of time may result in eye strain.
For comfort and efficiency, use the ergonomic guidelines when setting up and using your computer.
Laptops are not necessarily designed for continuous operation as office equipment. If you intend to use you laptop continuously,
it is recommended that you connect an external keyboard.
● Position your computer so that the monitor and keyboard are directly in front of you as you work. Special shelves are
available (from Dell and other sources) to help you correctly position your keyboard.
● Place the external monitor at a comfortable viewing distance. The recommended distance is 510 mm to 610 mm (20 in to 24
in) from your eyes.
● Ensure the monitor is at eye level or slightly lower when you are sitting in front of the monitor.
● Adjust the tilt of the monitor, its contrast and brightness settings, and the lighting around you (such as overhead lights, desk
lamps, and the curtains or blinds on nearby windows) to minimize reflections and glare on the monitor screen.
● Use a chair that provides good back support.
● Keep your forearms horizontal with your wrists in a neutral, comfortable position while using the keyboard or mouse.
● Always leave space to rest your hands while using the keyboard or mouse.
● Let your upper arms hang naturally at your sides.
● Sit erect, with your feet resting on the floor and your thighs level.
● When sitting, ensure the weight of your legs is on your feet and not on the front of your chair seat. Adjust your chair’s height
or use a footrest, if necessary, to maintain proper posture.
● Vary your work activities. Try to organize your work so that you do not have to type for extended periods of time. When you
stop typing, try to do things that use both hands.
● Keep the area under the desk clear of obstruction and cables or power cords that may interfere with comfortable seating or
present a potential trip hazard.
