Failure to observe these precautions could result in serious injury or death to personnel. Also included are explanations of safety and hazardous materials icons used within the technical manual. WARNINGS • Do not touch, ingest, or inhale particles of a broken objective lens. Lens contains germanium, which is slightly toxic if ingested or inhaled. Fragments may be sharp enough to cut personnel if touched. • Do not open, crush, puncture or otherwise mutilate batteries. Handle leaking batteries with rubber or plastic gloves. Get medical attention for any skin or respiratory irritation. • Batteries contain materials that are potentially hazardous and harmful to the environment. Turn depleted, leaking or damaged batteries in to next higher level of maintenance for disposal in accordance with unit Standard Operating Procedures (SOP). • Do not expose batteries to open flame or high temperatures. Batteries may explode or leak and cause personnel injury. • Do not expose batteries to water. Batteries may short circuit and/or flammable or noxious gas may be released that may cause a fire or injury to personnel. • Do not install batteries backwards, mix types of batteries, or mix used/new batteries. Batteries may explode or leak and cause personnel injury and/or equipment damage. • When using batteries other than the AA L91 (LiFeS2), the low battery indicator may not activate in time to provide sufficient warning to change batteries.
b
• Do not recharge AA L91 (LiFeS2) or alkaline batteries. Batteries may explode or leak and cause personnel injury. Refer to the Universal Battery Charger technical manual for directions on how to safely recharge the AA NiMH battery. • Do not short-circuit battery terminals. Batteries may explode or leak flammable or noxious gas, causing injury to personnel or damage to equipment. • Ensure weapon is not loaded and safety is on before installing or removing bracket/TWS to weapon. A loaded weapon may accidentally discharge, causing injury or death. • Ensure weapon safeties are on before installing or removing bracket/TWS to weapon. A loaded weapon may accidentally discharge, causing injury or death. • Remove eye from eyecup before firing MK19 machine gun. Recoil of MK19 machine gun may cause injury to personnel. • Ensure safeties are in place before sight-aligning weapon. Weapon may accidentally discharge, causing injury or death. • Unit deliberate decon SOP must be followed as the following procedures do not provide total decontamination. Protective mask and gloves should be worn when handling until total decontamination is completed by the decon lab. • The TWS is not light secure in Emergency mode. Use Emergency mode only if circumstances do not require light discipline. • Isopropyl alcohol vapors are harmful. Avoid prolonged or repeated breathing of vapors or solvent contact with skin. Use only with adequate ventilation. Isopropyl alcohol is flammable and should not be used near open flame. In the event of ingestion seek medical assistance. • Do not store batteries in TWS. Heat generated from the system in transit case may cause TWS to become hot.

HOW TO USE THIS MANUAL The safest, easiest, and most efficient way to operate and maintain the Thermal Weapon Sight (TWS) is to use this manual. Knowing what’s in this manual and how to use it will save you time and work, so take the time to learn how to use it. If this is the first time you are using this manual, be sure to completely read this section first. ORGANIZATION This manual is divided into four chapters: Chapter 1: Introduction – provides: • General Information • Equipment Description and Data • Principles of Operation Chapter 2: Operating Instructions – provides: • Description of Operator Controls and Indicators • Preventive Maintenance Checks and Services • Procedures for Operation Under Usual Conditions • Procedures for Operation Under Unusual Conditions Chapter 3: Operator Maintenance Instructions – provides: • Operator Troubleshooting Procedures • Operator Maintenance Procedures Appendix: Supporting Data – includes: • References • Components Of End Item (COEI) & Basic Issue Items (BII) • Additional Authorized List (AAL) • Expendable and Durable Items List (EDIL) • Quick Reference Card WHERE TO START If you’re using the manual for operating instructions, you will locate the procedures in the Operating Instructions, Chapter 2. If you are using the manual to replace a part (e.g., batteries) that you already know is bad, you will locate the replacement procedure in the Operator Maintenance Instructions in Chapter 3. If you do not know why a specific malfunction exists with the TWS, perform TWS Troubleshooting x
procedures located in the Operator Troubleshooting Procedures in Chapter 3. Before performing a procedure, read through it to determine if you have everything you need to perform the job. Familiarize yourself with the potential hazards described by the WARNINGS and CAUTIONS. You must familiarize yourself with the entire maintenance procedure before beginning the maintenance task. HOW TO USE A MAINTENANCE PROCEDURE The first page of a maintenance procedure, which is referred to as the setup page, contains supplementary support information you will need to perform that procedure. The following paragraphs describe all the blocks of information you will find there. TOOLS: If any tools are required, the tool will be listed as the first item under this heading. SUPPLIES: If any expendable or durable supplies are needed to perform the task, they are listed under this heading along with a reference to the item in Appendix D. If more than one of an item is required, the required quantity is provided. Appendix D gives you all the detailed information necessary to requisition the item if you don’t have it on hand. REFERENCING WITHIN THIS MANUAL Referencing from one procedure to another within this manual is by paragraph number. Paragraph references are preceded by the character “¶”. When you are referred to another procedure, you must read the setup page information for that procedure to determine what supplies may be required. SPECIAL FEATURES The front cover index lists the sections of the manual most commonly used. Bleeder edge tabs are used to quickly locate these sections in the manual. To locate a section, find the bleeder edge on the side of the manual that aligns with the bleeder edge on the front cover, and open to that page. The title of the section is boxed on that page.

CORROSION PREVENTION AND CONTROL (CPC)
Corrosion Prevention and Control (CPC) of Army materiel is a continuing concern. It is important that any corrosion problems with this item be reported so that the problem can be corrected and improvements can be made to prevent the problem in future items. Corrosion specifically occurs with metals. It is an electrochemical process that causes the degradation of metals. It is commonly caused by exposure to moisture, acids, bases, or salts. An example is the rusting of iron. Corrosion damage in metals can be seen, depending on the metal, as tarnishing, pitting, fogging, surface residue, and/or cracking. Plastics, composites, and rubbers can also degrade. Degradation is caused by thermal (heat), oxidation (oxygen), solvation (solvents), or photolytic (light, typically UV) processes.

PRINCIPLES OF OPERATION
FUNCTIONAL DESCRIPTION
The TWS is an IR imaging sensor used for target acquisition under varied visibility conditions. Thermal IR light energy emitted by the scene is gathered by the Objective Lens and focused onto the Focal Plane Array (FPA). The FPA converts IR energy into a digital video signal. The digital video signal is processed by the electronics, which then drives a micro-display to form a visible monochrome image. The visible image is then magnified, by the Eyepiece lens, for viewing by the Operator. Refer to the TWS Simplified Block Diagram, Figure 1-6. Lens Cap. The Lens cap protects the Objective Lens exterior surface from damage and contamination when the TWS is not imaging. The Lens cap is manually positioned by the Operator. Objective Lens. The Objective Lens gathers IR light emitting from the scene within the Lens’ FOV. The Objective Lens passes Thermal IR energy while rejecting all other wavelengths. The Objective Lens then focuses this energy onto the FPA. The Objective Lens provides a manual focus adjustment to bring scene objects into sharp focus (4m (LWTS/MWTS), 8m (HWTS). Calibration Shutter. The calibration function is performed by a motor driven flag-style Shutter. The Shutter closes for 0.5 seconds, blocking the optical path to permit the electronics to calibrate the image. A momentary image freeze occurs during calibration. The calibration function activates at power on, transition from Standby to Operate via the Eyecup, and when manually commanded by the operator.
1-20
Figure 1-6 TWS Simplified Block Diagram 1-21
FPA. The FPA converts incident IR energy into a digital video signal. Electronics. The electronics: • Convert and regulate power supplied from the Batteries or an external power source connected to the I/O port, into the voltages necessary to operate the electronics. • Processes the Operator control inputs. • Provides the drive signal for the Shutter Motor. • Store TWS programming. • Processes the raw digital video from the FPA, including NonUniformity Correction (NUC), gain, level, polarity, electronic zoom (FOV), and overlay of reticles and symbology. • Drives the Liquid-Crystal Display (LCD). • Converts the processed digital video stream to an RS-170 analog video signal suitable for driving television monitors and outputs this signal via the I/O port. • Provides a digital video stream output of either raw or processed digital video to the I/O port for maintenance use. • Provides a RS-422 serial communications interface for the TWS via the I/O Port for maintenance purposes. Backlight. The Backlight is a Light Emitting Diode (LED) illumination source for the LCD. The Backlight is illuminated by the standby override switch or in emergency mode. The Brightness level of the Backlight is adjustable by the Operator. Display. The LCD converts the Processed Video stream into a visible, monochrome image. Eyepiece Lens. The Eyepiece Lens magnifies the visible image from the display for viewing by the Operator. The Eyepiece provides a manual Operator diopter adjustment to set the display focus to the users eye (–6 to +2 Diopters).
1-22
Eyecup. The Eyecup provides a light seal to the Operator’s face for light security and to prevent glare. Compression of the Eyecup activates the Standby Override switch transitioning TWS from Standby to Operate. The eyecup properly positions the user’s eye for optimal viewing of the display. The Eyecup provides limited recoil protection to the Operator. The Eyecup contains flaps to assist in light security and minimize entrapment of debris and lens contamination. Batteries. AA Batteries loaded in a removable cassette provide the power source to operate the TWS when not powered from an external source (via the I/O connector). Controls. The Control interface allow the user to select or adjust the following: mode, brightness, gain, level, polarity, FOV, reticle selection, reticle adjustment and reticle polarity. With the exception of Mode, controls are inactive in Standby. See ¶2-1 for a detailed description of control functions. I/O Port. The I/O port is a connector interface for providing external power, outputting analog or digital video, and performing bidirectional serial communications. At the Operator level, the I/O port may be used to output analog video to a television monitor and/or input external power. I/O port is activated for video output when in the Operate Sub-Mode (Eyecup is depressed), EMER, or ZERO. External power may be applied at any time. Mount Assembly. The Mount Assembly (Rail Grabber) consists of a mechanical interface to the rail of the host weapon. The Rail Grabber/ Mount Assembly uses a ratcheting torque-limiting mechanism or two torqued down nuts, to ensure consistent mounting forces.
