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 Nyx-7 PRO 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.
