Engine Clear Aperture Notes
Obstructing the engine clear aperture can result in one or more of the following effects:
•
A captured image with non-uniformly illuminated areas.
•
Obstructing the imaging field of view.
•
Obstructing the aiming pattern.
Note for Engine Mounting in a Hands-Free Application
For optimum performance in presentation mode, allow only bar codes to enter the engine clear aperture. Other
moving objects in the engine clear aperture can cause a false trigger of the object detection system. For example,
in a table-top mounted application the engine should face down such that the clear aperture covers an area of the
table that is free from moving objects.
