Prior to any maintenance action (e.g., purging or charging M1A1 collimator) check for illumination using following pro-

cedure:

Device must be kept in the dark for at least four hours prior to performing the illumination test. This is to pre-

vent exterior light from activating the phosphor.

Adjust eyes to dark and check for illumination in the dark or a low light environment. If slight glow/haze ap-

pears, device is considered illuminated and maintenance actions may proceed.

If illumination is not observed, source is considered broken. Entire device must be evacuated to depot level

maintenance for repair/disposal (refer to AR 385-11). Take the following actions:

(a)

Seal entire device in two plastic bags (item 7, Appx B) and place in a strong, tight container (such as fiber-

board box (item 9, Appx B) with all seams secured using tape (item 36, Appx B) (masking tape is not autho-

rized).
