Section 3. TECHNICAL PRINCIPLES OF WORK
See chapter 2 section 1 DESCRIPTION, USE OF CONTROLS AND INDICATORS
Section 1. DESCRIPTION, USE OF GOVERNING BODIES AND INDICATORS
2-1. VERTICAL ADJUSTMENT
Binocular attachment moves up or down to fit the distance of the operator from the eyes to the helmet. Vertical movement is carried out by turning the adjustment knob vertically. The adjustment is self-locking.
2-2. ADJUSTMENT OF THE MONOCULAR RANGE IN THE HORIZONTAL PLANE (CRUSH)
Allows you to move the monoculars to the sides to fit the distance between the eyes. Range adjustment is done by turning the range adjustment knob. The adjustment is self-locking.
2-3. TILT ADJUSTMENT
Allows you to tilt the binocular. The tilt is performed by moving the tilt adjustment lever. This adjustment is self-locking.
2-4. HANDLE ADJUSTMENTS IN THE HORIZONTAL PLANE RELATING TO THE VIEW
Allows monoculars to move back and forth to ensure a comfortable distance of the night vision device to the eyes. This adjustment is self-locking.
2-5. RING FOCUSING OCULAR AND LENS
The eyepiece ring allows the operator to move the eyepiece in and out to get a clear image. Adjustable from +2 to -5 diopters. The lens ring allows the operator to move the lens in and out for a clear view of images ranging from 254 mm to infinity.
2-6. POWER SWITCHING SYSTEM
The switch is located on the power supply. Three switch positions: ON / OFF / ON. The three-position toggle switch allows you to switch between ANVIS batteries. Latching the toggle switch to ON provides power to the connectors for attaching the night vision device. When you connect the power of the aircraft, the power from the battery is automatically turned off. The OFF position cuts off both types of power supply.
2-7. LOW CHARGE BATTERY INDICATOR
The LED lights up with a dim red light in your field of view when there is about 30 minutes of active work left in the battery.
Section 2. CHECK BEFORE OPERATION
2-8. CHECK BEFORE OPERATION
but. Basic checks. These checks help the ANVIS operator determine if its equipment is ready for operation. Perform these before each use of the equipment. Report defects using the correct forms.
s Check wiring. Check for loose or frayed wires.
with. Low battery indicator. Set the system power switch to the lower ON position. Unscrew the bottom cover of the battery. The low battery indicator should light up. Lock the bottom battery cover back. Set the system power switch to the upper 0N position. Unscrew the top cover. The indicator must be activated. Set the power system switch to 0FF.
D. Lenses. Check the lens and eyepiece lenses for dirt, dust, fingerprints, scratches, chips or cracks. Inspect the lenses if necessary.
e. Contact binoculars. Check double contacts for dirt and wear. Send to AVUM if there are damages that cannot be repaired.
e. Adjustment. Move the settings throughout the range to ensure their free movement. Adjustments include a vertical adjustment knob, a length adjustment knob, a horizontal adjustment knob relative to the view, a tilt adjustment, an eyepiece focus ring, and a lens focus ring.

Step 5. Set the ANVIS power switch to OFF.
2-14. FIXING BINOCULAR TO ANVIS FASTENING
• Ensure the ANVIS power system is turned off.
• With the helmet on, put the binocular lens on the eyepiece with you.
• Secure the binocular securely in the power channels provided for it in the mount.
• Turn the binoculars to the working (down) position.
To avoid damage to the image amplifier tubes, use binoculars only at night. Do not turn on the device during daylight hours without protective filters.
The low battery indicator indicates that the binocular is powered by a weak battery with less than 30 minutes power. The power supply has an alternative battery. Set the power supply switch to another battery. If the low battery indicator goes out, this is a signal that power is being supplied from a more full battery. The low battery indicator also goes out if power is connected to the aircraft.
2-15. CHECK AVS-6 CORRECTIONS
Make a check in a dark room.
To check shading, sidelight, bright spots, blinking, flickering, or intermittent operation, check the binocular as follows:
An example of a faulty monocular. The fault is caused by a darkening in the lower left of the image circle.
SHADING. If shading is present, you will not see a completely round image. Shading always starts at the edge and moves inward. If you see the shading, turn it in AVUM
LATERAL COLOR is a bright area on the outside of the image area. Bring your hand to the lens to extinguish the whole world. If you see a side light, send in a binocular to AVUM.
BRIGHT SPOT. Bright spots may flicker or may be static. Bring your hand to the lens of the lens, extinguishing all the light. If you see bright spots, contact AVUM.
Make sure that bright spots or highlights are not caused by the light source in the scene. Ensure that shading is not the result of improper tilt, monocular collapse, or vertical settings.
USE BINOCULAR EXCLUSIVELY TOGETHER WITH THE INSURANCE NECK CORD TO PREVENT DYNAMIC DAMAGE TO THE BINOCULAR DURING EMERGENCY DISCONTINMENT OF FASTENING
