E. Chicken Wire

Chicken Wire is an irregular pattern of dark thin lines that can appear in the field 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 off 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.

Clean optional equipment with a soft brush (cloth), soap, and water as required.
