3.3 OPERATING PROCEDURES
3.3.1 OPERATING THE COMINI
Operating procedures should be performed in dark or nighttime conditions only.
CAUTION:
Use of the CO-MINI in brightly lit conditions may damage the image intensier 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.
3. Remove the objective lens cap and place it over the lens’ housing.
CAUTION:
Before removing the objective lens cap, verify that the photoreceiver is open.
