3.3 OPERATING PROCEDURES
3.3.1 OPERATING THE CO-MINI
Operating procedures should be performed in dark or nighttime conditions only.

Use of the CO-MINI in brightly lit conditions may damage the image intensifier tube.
1. Verify that the battery is installed as required.
2. Perform a visual estimation of the illumination level in the viewing area, using the reference data
presented in Appendix A. You can begin operating the CO-MINI if the illumination level is less than
1 lx.

CAUTION:
Before removing the objective lens cap, verify that the photoreceiver is open.
4. Verify that there are no bright light sources in the CO-MINI’s field of view. Turn the device on. After a
slight delay, a green glow will appear in the day scope’s output lens.
