2 Operating the System
2-2 AS-Series Operator Manual August 2010
Ergonomics
As in any occupation which requires you to perform the same motion repeatedly
during the course of you work, it is important to consider how you perform your
task. Always use proper operating procedures when operating the scanner. Follow
the directions for using and adjusting your chair and scanner. Using improper
procedure can result in a potentially serious injury. The AS-Series scanner has been
designed for safe operation by over 95% of the user population. Operation by
individuals with limited reach capability or who cannot follow the suggestions listed
should be avoided or limited in duration.
To reduce possible risks, we strongly urge you to follow these suggestions:
• Maintain an upright body posture. Avoid the tendency to slump in your chair. The
angle between your torso and thighs should always be close to 90 degrees.
• Adjust the seat height on your chair or the height of the scanner so that your
elbow is approximately even with the top of the work surface when your arms are
near your sides and your feet are flat on the floor. If this cannot be achieved with
normal chair and scanner adjustments, a footrest for shorter operators or scanner
leg extensions for taller operators should be used.
