4.3.2 CLEANING PROCEDURES
Clean the Zeus and optional items as follows:
1. Gently brush off any dirt from the equipment using only a clean, soft cloth.
2. Moisten the cloth with fresh water and gently wipe the external surfaces (except for optical sur-
faces).
3. Dry any wet surfaces (except for optical surfaces) with another clean, dry soft cloth.
4. Using a lens brush, carefully remove all loose dirt from optical surfaces (objective lens and eye-
piece).
5. Slightly dampen a cotton swab with ethanol and lightly and slowly wipe optical surface. Clean the
optical surface by circular movements from the center to the edge, not touching the lens holder and
changing cotton swab after each circular stroke. Repeat until the optical surface is clean.
6. Clean the battery contact surfaces and contact springs with a pencil eraser and/or alcohol and cot-
ton swabs.
CAUTION:
Thoroughly dry each item before replacing into the storage/carrying case.
4.3.3 BORE SIGHTING
Perform the Zeus bore sighting:
— When the Zeus is mounted to weapon for the first time;
— After repair of the Zeus/weapon;
— As the need arises (in case of systematic inaccuracy and missing the target).
Refer to Part 3.3.2 for boresight procedure.
4.3.4 BATTERY REMOVAL AND REPLACEMENT
