Arranging a comfortable and productive work area
When you arrange your computer, position your monitor and keyboard
directly in front of you. Place the mouse close to the keyboard so that you
can use it without stretching or leaning over to one side.
The system unit is usually kept on the floor under or beside your desk. Be
sure to place it in an area that will not block the space you need to put your
legs under the work surface.
Organize your desk to reflect the way you use work materials and
equipment. Place the things that you use most regularly, such as a mouse
or telephone, within the easiest reach.
Choosing a chair
You should adjust your chair so that your thighs are horizontal and there is
support for your lower back. Your feet should rest flat on the floor or on a
foot rest when you are seated and using your keyboard.
Positioning the monitor
Ÿ
Place the monitor at a comfortable viewing distance. You can also use
the length of your arm to determine a comfortable viewing distance.
Ÿ
Adjust your monitor so that the top of the screen is at, or slightly below,
eye level.
Ÿ
Keep the screen clean. For cleaning instructions, refer to the
documentation that comes with your monitor.
