Monitor Use
Specifications
Document Holders
When viewing your monitor, your head should not be tilted more
•
than 15 degrees forward.
You should not have to look up more than 5 degrees above horizontal
•
or down more than 30 degrees below horizontal for normal work
tasks, such as typing or reading.
When keying in data from a hard-copy document, placing it in a
document holder rather than on a flat surface will make it easier to
read. The following recommendations should be observed when using a
document holder:
The document holder should be at approximately the same height
•
and distance from your eyes as the screen, and as close to the
monitor as possible to prevent neck twisting. Some users prefer a
document holder mounted to the monitor while others prefer the
document holder positioned between the screen and keyboard.
If the primary task is to view documents rather than using the
•
monitor, the document holder may be placed directly in front of the
keyboard with the monitor slightly to the side.
To help reduce stress on your neck and prevent eye fatigue, try to
•
minimize the movement of your head and eyes while using a
document holder.
