4.3 IDENTIFICATION OF OPERATIONAL DEFECTS
4.3.1 OPERATIONAL DEFECTS
Operational defects relate to the reliability of the intensifier, and are an indication of instability. If iden-
tified, the user will need to return the CO-MR immediately. Operational defects include shading, edge
glow, flashing, flickering, and intermittent operation.
A. Shading
If shading is persistent, you will not be able to see a fully circular image (Figure 4-1). Shading is a very
dark, high-contrast area with a distinct line of demarcation present, and you cannot see an image
through it. Shading always begins on the edge, and will eventually migrate inward until it spans across
the entire image area. If you notice shading with your device, please contact Customer Support.
