****** Page 3 ****** SAFETY SUMMARY CAUTIONS • The ATN PVS-14 and ATN 6015 are precision optical instruments and must be handled carefully at all times to prevent damage. • Do not scratch the external lens surfaces or touch tiem with your fingers. • Wiping demisting shield with lens paper while wet or with wet lens paper can damage the coating. • To protect the image intensifier, keep the lens cap on the objec- tive lens when the monocular is not in use or when checked out in daylight conditions. • The IR illuminator is the light that is invisible to the unaided eye for use during conditions of extreme darkness. However, the light from the illuminator can be detected by others when using night vision devices. • If you use the rubber eyecaps for a long period of time, you may suffer skin inflammation. If you develop any symptoms, consult a doctor immediately. WARNING Do not carry batteries in pockets containing metal objects such as coins, keys, etc. Metal objects can cause the batteries to short cir- cuit and become very hot. CAUTION: THIS PRODUCT CONTAINS NATURAL RUBBER LATEX WHICH MAY CAUSE ALLERGIC REACTIONS. a

****** Page 4 ****** WARNING Toxic Material The image intensifier’s phosphor screen contains toxic materials. • If an image intensifier breaks, be extremely careful to avoid inhaling the phosphor screen material. Do not allow the mate- rial to come in contact with the mouth or open wounds on the skin. • If the phosphor screen material contacts your skin, wash it off immediately with soap and water. • If you inhale/swallow any phosphor screen material, drink a lot of water, induce vomiting, and seek medical attention as soon as possible. WARNING The monocular will not be turned off automatically when flipped up. The monocular must be turned off by the power switch. WARNING The compass illuminator can be seen by others using night vision devices. WARNING Do not use contaminated eyecup or eyeguard. They must be replaced. WARNING When installing the headmount over the protective mask, be careful not to break the protective mask seal around your face. b

****** Page 5 ****** EQUIPMENT LIMITATIONS To avoid physical and equipment damage when using the AT N PVS-14 and ATN 6015, carefully read and understand the following safety precautions. • The equipment requires some night light (moonlight, starlight, etc.) to operate. The level of performance depends upon the level of light. • Night light is reduced by passing cloud cover, while operating under trees, in building shadows, etc. • The equipment is less effective viewing into shadows and other darkened areas. • The equipment is less effective through rain, fog, sleet, snow or smoke. • The equipment will not “see” through dense smoke. NOTES • At operating temperatures below -200C (-40F), alkaline bat- teries are not recommended, as operating life will be severely reduced. Lithium-iron disulfide 1.5V AA batteries or equivalent should be used below -200C (-40F). • The purpose of the illuminator is to view at close distance up to 3 meters when additional illumination is needed. CAUTION • The ATN PVS-14 and ATN 6015 are a precision optical instru- ment and must be handled carefully at all times to prevent damage. • Be careful when leaving the helmet mount in the flipped up position or removing the helmet mount from the helmet, damage can result. c

****** Page 13 ****** TDA TOE Vdc Standard Form Table of Distribution and Allowances- Technical Manual Table of Organization and Equipment- Unit of Measure Volts, direct current 1.1.6. GLOSSARY BLACK SPOTS. These are cosmetic blemishes in the image inten- sifier of the MUNVM or dirt or debris between the lenses. BRIGHT SPOTS. These defects can appear in the image area of the MUNVM. This condition is caused by a flaw in the film on the microchannel plate. A bright spot is a small, nonuniform, bright area that may flicker or appear constant. Bright spots usually go away when the light is blocked out and are cosmetic blemishes that are signal induced. BROWPADS. Three hook-and-pile browpads are provided to adjust the headmount to fit different head sizes. The thin browpad (large head) comes attached to the headmount and the thick (small head) or medium browpads are stored in the carrying case. CAUTION. Condition, practices, or procedures that must be ob- served to avoid damage to equipment, destruction of equipment, or a long-term health hazard. CHICKEN WIRE. An irregular pattern of dark thin lines in the field- of-view either throughout the image area or in parts of the image area. Under the worst case condition, these lines will form hexago- nal or square-wave shaped lines. DARK (OR DARK AREA). A place in which there is very little light. It does not mean total darkness. Generally, this means conditions similar to a quarter-moon or starlit night. DARK-ADAPTED. Having ones eye adjusted to the monocular’s output under low light conditions. DIOPTER. A unit of measure used to define eye correction. Adjust- ments to the diopter adjustment will provide a clearer image in each eye. 1-5

****** Page 14 ****** EDGE GLOW. This is a defect in the image area of the monocular. Edge glow is a bright area (sometimes sparkling) in the outer por- tion of the viewing area. EMISSION POINT. A steady or fluctuating pinpoint of bright light in the image area and does not go away when all light is blocked from the objective lens of the monocular. The position of an emission point within the image area of the monocular does not move. An emission point should not be confused with a point light source in the distance. FIXED-PATTERN NOISE. This is a cosmetic blemish in the im- age area characterized by a faint hexagonal (honeycomb) pattern throughout the viewing area that most often occurs at high light levels or when viewing very bright lights. Fixed-pattern noise is in- herent in the structure of the fiber optics and can be seen in every image intensifier if the light level is high enough. FLASHING. This is a defect in the image area of the monocular. The image appears to flicker or flash. FLICKERING. See “flashing.” GAIN. This is the number of times a night vision device amplifies light input. IMAGE INTENSIFIER. An electro-optical device that detects and amplifies ambient light to produce a visual image. INFINITY FOCUS. Adjustment of the objective lens so that a distant object, such as a star or the point light on a distant tower, forms the sharpest image. INTERMITTENT OPERATION. This is a defect in the image area of the monocular. See “flashing”. IR SOURCE. This is an IR Light Emitting Diode (LED). When turned on, the IR source provides additional illumination to enhance exist- ing light conditions used only for performing nearby tasks. LIGHT INTERFERENCE FILTER (LIF). This is a light protection fil- ter for the monocular. Use of this filter will result in a slight reduction in system gain. MICROCHANNEL PLATE. A current-multiplying optical disk that intensifies the electron image produced by the photocathode. 1-6

****** Page 15 ****** NOTE. Essential information of special importance, interest, or aid in job performance. PHOTOCATHODE. The input optic of an image intensifier that ab- sorbs light energy and in turn releases electrical energy in the form of an electron image. SCINTILLATION. A faint, random, sparkling effect throughout the image area. Scintillation is a normal characteristic of the image in- tensifier and should not be confused with emission points. Scintil- lation is more pronounced under low light conditions. Also called “video noise”. SHADING. The viewed image should be a full circle. If shading is present, you will not see a fully circular image. Shading is indicative of a dying photocathode and is caused by a defective vacuum seal of the image intensifier. Shading is very dark and you cannot see an image through it. WARNING. Conditions, practices, or procedures that must be ob- served to avoid personal injury or loss of life. 1-7

MECHANICAL FUNCTIONS FOR THE NVMPS NOTE The gain control is not present in 6015 or PVS-14NG model. 1-15

****** Page 24 ****** 1.3.2 OPTICAL FUNCTIONS The optical functions include an objective lens, image intensifier and eyepiece lens (Figure 1.6). The objective lens collects light re- flected from the night scene by the moon, stars, or night sky, inverts the image and focuses that image on the image intensifier. The im- age intensifier converts the captured light into a visible image and reinverts the image which can then be viewed through the eyepiece lens. PHOTOCATHODE MICROCHANNEL PLATE OBJECTIVE LENS PHOSPHOR SCREEN POWER SUPPLY IMAGE INTENSIFIER FIBER-OPTIC INVERTER EYE EYEPIECE LENS FIGURE 1.6. OPTICAL FUNCTION DIAGRAM 1.3.3. ELECTRONIC CIRCUIT FUNCTION The electronic circuit regulates the direct current voltage from the battery to the image intensifier and IR source as required. It also monitors the output voltage of the battery and turns on a low-bat- tery indicator when the available battery voltage is 1.9 — 2.1Vdc. a. Power Source The electronic circuit is powered by one battery. b. High Light Cut-Off The monocular will automatically cut off after 70 ±30 seconds of operation in daylight or bright room light. Individual bright lights (headlights, flashlights, or other concentrated light sources) will not actuate the high light detector located on the front of the monocular. To turn the monocular back ON, turn the power switch to RESET/ OFF position and then to ON again. 1-16

NOTE The TS-4348/UV Test Set can be used by Direct Support/lnter- mediate Level to perform the resolution testing 180 Day Serv- ice. If a system fails it must be tested on theTS-3895A/UV Test Set. NOTE Verify the resolution of the monocular using the TS-4348/UV Test Set at every opportunity. The resolution cannot be accu- rately measured without the test set. The following procedures are designed to check the performance of the image intensifier. a. Setup Before using the TS-4348/UV Test Set to set up and familia-rize yourself with its operation and the warnings and cautions associ- ated with that test equipment. NOTE • The resolution test must be performed in a darkened area. Your eyes must be dark-adapted to perform this test. Review the following test procedure before entering the dark area. • Expect cosmetic blemishes, such as chicken wire, black spots, and fixed-pattern noise, to stand out while viewing through the TS-4348/UV Test Set when it is on the high light level. This is acceptable. • The rejection of any MUNVM for cosmetic defects must be based on an outdoor evaluation and not the TS-4348/UV Test Set. b. Low Light and High Light Resolution Test Procedure Test the monocular for low light and high light resolution perfor- mance according to the following steps. (1) Place the HIGH/LOW switch on the test set to the LOW position. 2-14

****** Page 39 ****** (2) Install the LIF per paragraph 2.3.6. (3) Turn off the room light and let your eyes adjust to the dark. (4) Turn on the test set by setting the “II/OFF/III” switch to the “Ill” position. (5) Turn on the monocular and insert it into the test port on the test set. (6) Look through the monocular and view the projected pattern (see Figure 2.2.). If necessary, focus the eyepiece lens and then the objective lens to obtain the sharpest image. (7) The MUNVM monocular must be able to resolve Group 2, Ele- ment 2, under low light conditions to pass the test. If the MUNVM does not pass the test, return it to maintenance for repair. The op- erator must document resolution failures on the maintenance re- cord.

RESOLUTION FOR MUNVM READ THIS FOR HIGH LIGHT RESO- LUTION FOR MUNVM FIGURE 2.2. TS-4348/UV TEST SET PATTERN 2-15

****** Page 40 ****** NOTE For a pattern to be resolvable, three vertical bars and three horizontal bars must be visible. (8) Flip the HIGH/LOW switch to the HIGH position. (9) Again, look through the monocular and view the projected pat- tern (see Figure 2.2.). If necessary, refocus the objective lens and then the eyepiece lens to obtain the sharpest image. (10) The MUNVM must be able to resolve Group 3, Element 5, un- der high light conditions to pass the test. If the monocular does not pass the test, send it to a higher level of maintenance for repair. NOTE When using the TS-4348/UV Test Set, you are not viewing the entire image intensifier. Therefore, operational and cosmetic inspections must be done without the test set as specified in paragraph 2.2.3. (11) Look for flashing, flickering, or other nonstable behavior of the image intensifier. Also check the image intensifier for other opera- tional defects described in paragraph 2.2.3. To view the image in- tensifier under low light conditions, flip the HIGH/LOW switch to the LOW position and allow your eyes to become accustomed to the dark. If any unacceptable conditions are noted, send to a higher level of maintenance for repair. 2.2.3. INSPECTION CRITERIA FOR PROPER IMAGE INTENSIFIER OPERATION a. General As directed in the Preventive Maintenance Checks and Services table, image intensifier operation must be checked before each mission. This section provides information for the operator con- cerning what to look for, how to look for it, and how to determine if the MUNVM should be returned to the maintainer. CAUTION Perform the following inspection in the dark. To perform this inspection, attach the monocular to the headmount as described in paragraph 23.8. and turn the power switch to the ON position. Look through the monocular and view the image. 2-16

****** Page 41 ****** There are two groups of “defects” you may encounter — operational defects and cosmetic blemishes. Operational defects are an im- mediate cause to reject the MUNVM. Cosmetic blemishes are not a cause for rejection unless they become severe enough to inter- fere with the ability to perform the mission. The rejection of any MUNVM for cosmetic defects must be based on an outdoor evaluation and not the TS-4348/UV Test Set. b. Operational Defects These defects relate to the reliability of the image intensifier and are an indication of instability. If identified, they are an immediate cause for rejecting the MUNVM. They include shading, edge glow, flashing, flickering, and intermittent operation. (1) Shading. If shading is present, you will not see a fully circular image (see Figure 2.3). Shading is very dark and you cannot see an image through it. Shading always begins on the edge and mi- grates inward eventually across the entire image area. Shading is a high contrast area with a distinct line of demarcation. Return the MUNVM to the maintainer. SHADING FIGURE 2.3. SHADING NOTE Make sure the shading is not the result of improper eye-relief adjustment (refer to paragraph 2.4.2). (2) Edge Glow. Edge glow is a bright area (sometimes sparkling) in the outer portion of the viewing area (see Figure 2.4). 2-17

****** Page 42 ****** To check for edge glow, block out all light by cupping a hand over the objective lens. If the image intensifier is displaying edge glow the bright area will still show up. Return the MUNVM to the main- tainer. FIGURE 2.4. EDGE GLOW EDGE GLOW (3) Flashing, Flickering, or Intermittent Operation. The image may appear to flicker or flash. If there is more than one flicker, check for loose battery cap or weak battery. If weak or loose batteries are not the problem return the MUNVM to the maintainer. c. Cosmetic Blemishes These are usually the result of manufacturing imperfections that do not affect intensifier reliability and are not normally a cause for rejecting an MUNVM. However, some types of blemishes can get worse over time and interfere with the ability to perform the mission. If you believe a blemish is cause for rejection, record the specific nature of the problem on the maintenance forms and identify the position of the blemish by using the clock method and approximate distance from the center (e.g., 5 0’clock toward the outside, 2:30 near the center, or 1 midway). The following are cosmetic blem- ishes: (1) Bright Spots. A bright spot is a small, nonuniform, bright area that may flicker or appear constant (Figure 2.5.). Not all bright spots make the MUNVM rejectable. Cup your hand over the objective lens to block out all light. If the bright spot remains, return the MU- NVM to the maintainer. Bright spots usually go away when the light is blocked out. Make sure any bright spot is not simply a bright area 2-18

****** Page 43 ****** in the scene you are viewing. Bright spots are acceptable if they do not interfere with the operator’s ability to view the image or to perform the mission. EMISSION POINTS BRIGHT SPOTS FIGURE 2.5. BRIGHT SPOTS AND EMISSION POINTS (2) Emission Points. A steady or fluctuating pinpoint of bright light in image area that does not go away when all light is blocked from the objective lens of the monocular (Figure 2.5.). The position of an emission point within the image area does not move. Not all emission points make the MUNVM rejectable. Make sure any emission point is not simply a point light source in the scene you are viewing. Emission points are acceptable if they do not interfere with the operator’s ability to view the image or to per- form the mission. (3) Black Spots. These are cosmetic blemishes in the image in- tensifier or dirt or debris between the lenses. Black spots are ac- ceptable as long as they do not interfere with viewing the image. No action is required if this condition is present unless the spots interfere with the operator’s ability to view the image or to perform the mission. (4) Fixed-Pattern Noise. This is usually a cosmetic blemish char- acterized by a faint hexagonal (honeycomb) pattern throughout the viewing area that most often occurs at high light levels or when viewing very bright lights (see Figure 2.6.). This pattern can be seen in every image intensifier if the light level is high enough. This condition is acceptable as long as the pattern does not inter- 2-19

****** Page 44 ****** fere with the operator’s ability to view the image or to perform the mission. FIGURE 2.6. FIXED-PATTERN NOISE (5) Chicken Wire. An irregular pattern of dark thin lines in the field- of-view either throughout the image or in parts of the image area (see Figure 2.7.). Under the worst case condition, these lines will form hexagonal or square-wave shaped lines. No action is re- quired if this condition is present unless it interferes with the operator’s ability to view the image or to perform the mission. FIGURE 2.7. CHICKEN WIRE 2-20

****** Page 45 ****** 2.3. ASSEMBLY AND PREPARATION FOR USE 2.3.1. UNPACKING The following steps must be accomplished prior to each mission where the MUNVM is used. CAUTION Relieve air pressure inside shipping and storage case by pressing in on opposite sides of the case before releasing latches. (1) Release the latch securing top of shipping and storage case and open. (2) Check contents for completeness (see Figure 1.1 (3) Remove carrying case. Open carrying case (Figure 1.3.), re- move MUNVM, and check contents for completeness.

(9) Adjust the objective lens focus (Figure 2.1.) while observing an object until the sharpest image is obtained. 2.4.3. HELMET MOUNTED OPERATION CAUTION Take some precaution when using/handling the helmet mount. Most damage occurs when the helmet mount is left on the helmet when not needed for immediate use. Observe the fol- lowing cautions to significantly extend the useful life of the helmet mount. CAUTION • Do not use excessive force when changing the up/down posi- tion of the MUNVM. Excessive force can break the headmount/ helmet mount adapter. • Do not drop or throw the helmet with the helmet mount attached to it. • With the monocular in the flipped up position, do not flick the monocular down by shaking the helmet. This places signifi- cant stress on the helmet mount. • All Other Services — Return the helmet and the helmet mount to unit maintenance for direct mounting of the bracket via the helmet screws. Perform the following procedures for helmet mounted operation. 2-36

****** Page 61 ****** NOTE The helmet mount provides two positions for the user to posi- tion the MUNVM. The flipped down position allows the user to position the MUNVM directly in front of the eyes. The helmet mount also allows the user to rotate the MUNVM to a flipped up position when the MUNVM is not needed for immediate use. Both the flipped down and the flipped up positions have a positive stop which assures the user that the MUNVM is in the correct position. NOTE The headmount/helmet mount adapter allows the MUNVM to be rotated from the left to the right eye or vice versa. The MUNVM can be moved to the flipped up position with the headmount/ helmet mount adapter positioned to either the left or the right. (1) Ensure that the battery are installed per paragraph 2.3.2.

(5) Adjust the objective lens focus (Figure 2.1.) while observing an object until the sharpest image is obtained. 2.4.5. IR SOURCE OPERATIONS WARNING The IR source is a light that is invisible to the unaided eye for use during conditions of extreme darkness. However, the light from the IR source can be detected by the enemy using night vision devices. NOTE The purpose of the IR source is for viewing at close distances up to 3 meters when additional illumination is needed. (1) Pull the power switch knob out and rotate clockwise to the IR position. With the monocular held to the eye, observe that a red light appears in the eyepiece. This indicates that the IR source is operating. (2) For momentary IR, turn the power switch clockwise (without pulling) past the ON position. Observe that a red light appears in the eyepiece. 2-4.6. OPERATION WITH COMPASS WARNING The compass illuminator can be seen by others using night vision devices. CAUTION You will get inaccurate readings, when using the compass on any head or helmet mount with the magnet still installed. Only the magnet on the metal mount can be removed without caus- ing damage to the equipment, see paragraph 2.3.12. 2-39

****** Page 64 ****** NOTE • The compass reading is the magnetic North, not true North. • The compass reading is within 20 of correct absolute mag- netic bearing. Compass readings with mounted monocular (head mount or helmet mount) can be up to 150 of correct absolute magnetic bearing. This occurs mostly in the East (900) to West (2700) and less in the North (3600) to South (1800) reading. If the compass is inadvertently magnetized this could cause an additional 150 error. • The objective lens focus can be fine tuned after installation, but in order to obtain an accurate reading, the compass must be vertical. (The compass image must be level.) (1) Install per paragraph 2.3.12. (2) If necessary to more clearly view your distant object, adjust the objective lens focus slightly by gripping the compass and turning clockwise. NOTE • Increase brightness slowly. Excessive brightness may burn a temporary image into the image intensifier. Do not increase brightness any more than is necessary to clearly read the compass heading. •The monocular must be focused at or near infinity for proper compass operation. 320 FIGURE 2.22. VIEW THROUGH INSTALLED COMPASS 2-40

****** Page 65 ****** (3) To view the compass through the monocular, grip the compass with index finger on top and thumb on illumination button on bottom. Press button slowly with thumb until proper brightness is obtained. The image should appear as shown in Figure 2.22. (4) The compass readings should change when you move your head from side to side. Rotate or tap compass slightly to ensure compass is operating correctly. Hold the monocular in a level posi- tion to assure free rotation of the compass scale. (5) The tick mark closest to the center of the lighted display is the compass bearing. The tick marks are in degrees, with longer tick marks every five degrees and bearing labels every 10 degrees. 2.4.7. OPERATION WITH 3X MAGNIFIER (1) Install per paragraph 2.3.13.
