4.3 MAINTENANCE
4.3.1 GENERAL
The Cipher operator maintenance consists of operational tests, inspections for unit serviceability,
cleaning and mounting procedures, corrective actions (troubleshooting and replacement of a limited
number of parts). Maintenance instructions covered elsewhere in this manual (PMCS, troubleshooting,
etc.) are not repeated in this section.
CAUTION:
The Cipher is a precision electro-optical instrument and must be handled carefully at all times
to prevent damage.
CAUTION:
DO NOT dismantle the equipment.
4.3.2 CLEANING PROCEDURES
Clean the Cipher 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 lens brush, carefully remove all loose dirt from optical surfaces (objective lens and eyepiece).
5. Slightly dampen a cotton swab with ethanol and lightly and slowly wipe the optical surface. Clean the
optical surface using 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:
Dry thoroughly each item before replacing into the storage/carrying case.
4.3.3 BATTERY REMOVAL AND REPLACEMENT
Refer to Part 3.1.1 for the Cipher’s battery installation procedures.
Replace the remote control batteries as follows:
1. Using a screwdriver, unscrew the four screws (A, Figure 4-1) that secure the cover to the bottom of
the unit. Remove the cover.
2. Replace the batteries with two new ones (CR2016, 3V). Insert the batteries, aligning the polarity
markings (+/-) on the batteries with those on the compartment.
3. Replace the cover and retighten the screws (A).
