E. Chicken Wire
Chicken Wire is an irregular pattern of dark thin lines that can appear in the eld of view, either through-
outtheimageareaorinsectionsoftheimagearea(SeeFigure4-5).Intheworst-casescenario,these
lines will form hexagonal or square, wave-shaped lines. No action is required if this condition is present,
unless it interferes with the user’s ability to view an image or their ability to perform missions.

4.4 MAINTENANCE
4.4.1 GENERAL
The section regarding CO-MINI operator maintenance consists of operational tests, inspections for unit
serviceability, cleaning and mounting procedures, troubleshooting, and replacement instructions for
a limited number of parts. Maintenance instructions covered elsewhere in this manual (PMCS, trouble-
shooting, etc.) are not repeated in this section.
CAUTION:
The CO-MINI is a precision electro-optical instrument, and must be handled carefully at all
times to prevent damage to body and mechanisms.
4.4.2 CLEANING PROCEDURES
CAUTION:
Thoroughly dry each item before placing them into the storage case.
Clean the CO-MINI and IR850 as follows:
1. Gentlybrushoanydirtfromthedevice’sbodyusingaclean,softcloth.
2. Moisten the cloth with fresh water and gently wipe external surfaces (except for glass surfaces).
3. Dry any wet surfaces (except for glass surfaces) with another clean, soft, dry cloth.
4. Usingalensbrush,carefullyremoveallloosedirtfromtheglasssurfaces.
5. Slightly dampen a cotton swab with ethanol. Gently and slowly wipe the lenses (including the pho-
toreceiver). Without touching the lens holders, clean the glass surfaces in circular movements, be-
ginning in the center and moving out towards the edge. Change the cotton swab after each circular
stroke. Repeat until the glass surfaces are clean.
6. Clean the battery surfaces and contacts with a pencil eraser and/ or alcohol-dampened cotton
swabs.
