AN/UAS-11 Night Vision Sight Technical manual
The AN/UAS-11 Night Vision Sight is a self-contained infrared system that allows operators to track targets in darkness, daylight, and degraded field conditions. The device is cooled by a rechargeable coolant cartridge and can be powered by a vehicle power conditioner or an attached rechargeable battery. The Night Sight converts infrared energy into visible light that can be viewed through a binocular eyepiece at the rear of the device. You can select between a wide or narrow field of view depending on the distance to the target.

Remove power before removing and replacing any assembly, subassembly, or component.
HIGH VOLTAGE is used in this system.
Death or injury can result if you do not observe safety precautions.
WARNING
RADIATION HAZARD
The antireflective coating on all infrared optics contains slightly radioactive thorium fluoride.
Potential hazard may result from ingestion (swallowing or inhaling) of this coating material.
Dispose of broken lenses and optics in accordance with AR 385-11.
Chemical agent resistant coating (CARC) is extremely toxic and flammable.
Never use where sparks, smoking or open flame may be present. CARC, if improperly used, may cause long term health problems.
Avoid contact with skin, breathing of fumes, or ingestion of dried particles. Use must be monitored by the local safety office and preventive medicine support activity.
Refer to TM 43-0139 for applicable safety precautions prior to removal or application of CARC.

HOW TO USE THIS MANUAL
1.
Take a few minutes to look through this manual.
We’ve designed this manual so that it will be easy for you to find and perform the procedures you need.
2.
If the Night Sight needs repair and you know what’s wrong with it, here’s what you do: a) Turn to the index and check for a paragraph on the component you want to remove and replace.
b) Turn to the paragraph.
Under the paragraph title, you’ll find the tools, materials, and equipment condition needed to perform the procedure. If there are no tools or materials needed, it will also be noted here. If you have more than one of a specific type of tool (for example, two different screwdrivers) the text will indicate which tool to use in the necessary steps.
If there is no equipment condition needed to prepare the
Night Sight for removal procedure, it will be noted that the Night Sight is assembled.
c) To remove the bad component, perform the removal procedure.
d) To install the new component, perform the replacement procedure.
The
Night Sight should now be ready to operate.
e) Perform the troubleshooting procedure paragraph 3-2 to verify repair of
the Night Sight.
3.
If the Night Sight needs repair and you don’t know what’s wrong with it, you go to the troubleshooting procedures.
Troubleshooting procedures are written in the flow chart style.
Each set of instructions is written in a box and the boxes are connected by arrows.
By following the arrows, you can work your way through the procedure.
The chart on the following page tells you what the various boxes mean.

•
Prior to starting troubleshooting, insure the Night
Sight has freshly charged battery and fully charged coolant cartridge installed.
Follow steps in order given in the procedures. Do not skip any steps.
When you enter the “NO” chain, perform the procedure and/or repairs as instructed in the corrective action block.
Unless otherwise specified, after performing the corrective action of the “NO” chain always return to the “START” of the procedure you were checking. When more than one corrective action may be required, perform the first corrective action, return to
“START”, and repeat the procedure.
If
the problem still exists, perform the next corrective action and repeat.
The eyeshield assembly may be removed during troubleshooting to aid in observing raster. A socket-head screw key is stored in the Night Sight field handling case for this purpose.
If corrective action contained in this manual does not remedy the malfunction, turn AN/UAS-11 Equipment Set in through normal channels of supply.

TOUCHUP PAINTING
MATERIALS:
CARC paint (Item 5, Appendix D)
Chemical agent resistant coating (CARC) is extremely toxic and flammable. Never use where sparks, smoking or open flame may be present. CARC, if improperly used, may cause long term health problems. Avoid contact with skin, breathing of fumes, or ingestion of dried particles. Use must be monitored by the local safety office and preventive medicine support activity.
Refer to TM 43-0139 for applicable safety precautions prior to removal or application of CARC.
Use masking tape to ensure that no paint is applied to bolt holes, attaching surfaces, preformed packings, preformed packing grooves, or surfaces treated with lubricant.

This fine document...
Was brought to you by me:
Liberated Manuals -- free army and government manuals
Why do I do it? I am tired of sleazy CD-ROM sellers, who take publicly available information, slap “watermarks” and other junk on it, and sell it.
Those masters of search engine manipulation make sure that their sites that sell free information, come up first in search engines. They did not create it...
They did not even scan it... Why should they get your money? Why are not letting you give those free manuals to your friends?
I am setting this document FREE. This document was made by the US
Government and is NOT protected by Copyright. Feel free to share, republish, sell and so on.
I am not asking you for donations, fees or handouts. If you can, please provide a link to liberatedmanuals.com, so that free manuals come up first in search engines:
