Section Ill. Principles of Operation
1-14 MECHANICAL FUNCTIONS
The driver’s viewer can rotate 45° (AN/VVS-2(V)1, AN/VVS-2(V)1A andAN/VVS-2(V)4) or 30° (AN/VVS-2(V)2, AN/VVS-2(V)2A and AN/VVS-2(V)3) toeither side of the straight-ahead position. The straight-ahead position is main-tained by a quick-release plunger and a detent in the Viewer Mount Assembly(AN/VVS-2(V)1 and AN/VVS-2(V)2) or a roller assembly and a detent in theViewer Mount Assembly (AN/VVS-2(V)1A, AN/VVS-2(V)2A,AN/VVS-2( V)3 andAN/VVS-2(V)4). A firm twisting motion will move the periscope out of the de-tent. A single control turns power ON or OFF and adjusts brightness of theviewed image.
1-15 OPTICAL FUNCTIONS
Optical Function Diagram (Fig. 1-3). Low level light from a viewed area entersthe entrance window of the periscope and is reflected down through the Objec-tive Barrel Assembly to the image intensifier. The image intensifier increasesthe magnitude of the low level light and transmits it to the eyepiece prism whichreflects a brighter image of the viewing area to the viewing lens. The viewinglens provides the driver a green, but visible, image of the viewing area for driv-ing at night.
1-16 ELECTRICAL FUNCTIONS
Power (Fig. 1-4). Two sources of power are available to operate the nightperiscope: Vehicle power of 28 vdc or battery 3.0 vdc. The night periscopecontains an electronic circuit which converts the 28 vdc vehicle power to 2.7vdc to operate the night periscope. A single lithium battery can be used topower the night periscope when vehicle power is not available. The night peri-scope also has an Electronic Control Assembly (ECA) which protects the nightperiscope from bright light by cutting off the power when the night periscope isexposed to damaging high light levels. The power is restored within a fewseconds after the target brightness is reduced to a non-damaging level,

coins, keys, etc. Metal objects can cause the battery to shortcircuit and become very hot. In the case of BA-5567/U (lithium)battery, a short can cause them to EXPLODE.
Do not heat, puncture, disassemble, short circuit, attempt to re-charge, or otherwise tamper with battery.
The contents of the BA-5567/U (lithium) batteries are extremelyirritating to the eyes, nose and throat; therefore, be careful whendiscarding the batteries. To prevent explosion, batteries shouldnot be disposed of by burning, Dispose of batteries perTB 43-0134.
The batteries have safety vents to prevent explosion. Whenthey are venting gas, you will smell it (very irritating) or hear thesound of gas escaping. When the safety vents have operated,the batteries are fairly safe from bursting but will be hot andmust be handled with care.
Batteries used in night periscope may EXPLODE if overheated.
DO NOT use batteries which look bulged or have burst. Turn inthese batteries in accordance with TB 43-0134. Contact yourunit safety officer for help with large quantities of bulged or burstbatteries.
Inspect battery for defects (bulging positive (+) terminal or bulg-ing sides). Do not use a defective battery in the night periscope.
Remove battery from storage.

2-4. INITIAL ADJUSTMENTS, CHECKS, AND SELF-TEST
As directed in the PMCS table, image intensifier operation must recheckedbefore each use. This section provides information for the operator concerningwhat to look for, how to look for it, and how to determine if the night periscopeshould be returned to the maintainer. All non-mission capable conditions shouldbe recorded on the appropriate maintenance forms so the maintainer can takecorrective action. While formal determination of a defective image intensifier ismade by unit maintenance personnel, the operator is the ultimate person re-sponsible for determining whether the image intensifier operation interferes withhis ability to perform his mission. If maintenance personnel determine that theimage intensifier performance meets the specification and the operator findsthe performance interferes with his ability to perform the mission, he must recordthe problem on the appropriate maintenance form (DA Form 2404) and returnthe system to the maintainer.
a. Inspection Criteria for Proper Image Intensifier Operation.
Perform the following inspection in the dark or you may damagethe image intensifier.
NOTE
• The night periscope must be checked before each use for properoperation. Inspect (view the image through the eye piece) forthe following conditions before operation.
• Your eyes must be dark-adapted to perform this procedure. Thistakes at least 10 minutes or longer if you have been exposed tobright lights. Review the following procedures before enteringthe dark area.

(3) BRIGHT SPOTS - These are cosmetic defects in the image intensi-fier. A bright spot is a small, nonuniform, bright area that may flicker orappear constant (Fig. 2-5). Not all bright spots make the viewer unac-ceptable. Bright spots are acceptable if they do not interfere with theability to perform the mission. If bright spots do interfere, send theviewer to higher level of maintenance.
(4) BLACK SPOTS & STREAKS - These are cosmetic blemishes in theimage area of the night periscope. Black spots or streaks (Fig 2-5) areacceptable as long as they do not interfere with image viewing. Noaction is required if this condition is present unless the spot or streaksinterfere with the ability to perform the mission.

b. 50 Foot Focus Check Procedure
NOTE
The focus check must be conducted in a dark location with atleast a light level of a quarter moon. Allow time for your eyes tobecome dark adapted (approx. 10 minutes) prior to focus check.The tester (driver or maintainer) should have corrected vision to20-20. Clean all external lenses prior to focus check.
(1) Post test target (SM-D-771 396, NSN 5855-01-027-1567) 50 feet(+5 ft.) from the viewer as measured from the entrance window of theentrance head assembly to the target (Fig 2-8). The focus check canbe accomplished either mounted (in a vehicle) or dismounted (work-bench, table or stand). Some units post the test target on a fence orwall near the motor pool area where vehicles would drive-up to a 50 ft.premeasured spot and complete the procedure below.
(2) Turn on the viewer and adjust ON/OFF, Brightness Control knob tocomfortable viewing of the test target. The test target should be in thecenter of the viewing lens. If the test target cannot be resolved due toextreme low light levels, a flashlight can be used to illuminate the tar-get.
(3) Acceptable Focus. The viewer passes the focus check if the viewercan resolve pattern B which is the center pattern of 5 horizontal and 5vertical bars. To resolve pattern B, you must be able to distinguishthat the 5 horizontal bars are in fact horizontal and that the 5 verticalbars are clearly vertical. This procedure requires you to scan left toright for the vertical bars and up and down for the horizontal bars asyou observe pattern B.
(4) Unacceptable Focus. If the viewer fails the focus check it must bepulled from service immediately and reported /returned to higher levelof maintenance for refocusing. ONLY DS REPAIR SHOPS CANADJUST THE FOCUS.
