Ensure it is not trapped or folded. 16) Fit a DP part and serial number label to the lens fitted into to the projector (take the serial number info from the lens packaging box). Print the part and serial numbers onto a small silver anti-tamper label and fix onto the lens so that it does not show outside of the projector chassis. On the fixed lens fit the label to the top of the square housing in the position as illustrated.
