1. INTRODUCTION

1.1 SCOPE

This manual provides instructions for the operator to use and
maintain the Aviator's Night Vision Goggles Model NVS 6
(Fig.1-1).

The NVS 6 is a self-contained, helmet-mounted passive night
vision binocular device that provides the capability for pilots to
fly in terrain flight modes at night.

The system amplifies ambient light from sources such as the
moon, stars and sky glow, so the viewed scene becomes clearly
visible to the operator.

The NVS 6 has the following important features:

•   Powered by batteries
•   Low-battery indicator on the helmet mount blinks, if the
    battery voltage drops below safe limits
•   Eye-span, vertical distance, tilt, eye relief, diopter and focus
    adjustable
•   Binocular may be flipped up and stored away from the eyes
    in an emergency.

1.2.1 Mount assembly

The mount assembly or the mount (Fig.1-3) attaches to the
existing visor guard of helmets and contains a vertical adjustment
for moving the binocular up or down, a fore-and-aft adjustment
for optimal viewing of the field of view and tilt adjustment for
optimal line-of sight viewing. It also allows the binocular to be
stowed in the up position away from the eyes and to be pulled off
or to break away during a crash load of 10g force or more. The
bottom of the mount incorporates: a low-battery indicator (red
LED) that either comes on or blinks to alert the pilot when
remaining battery life is approximately 30 minutes; a connector
plug that provides the electrical contacts and mechanical quick
interconnection mechanism for binocular.

                                11
1.5 OPTICAL FUNCTIONS

The binocular assembly (the binocular) is an electro-optical
system consisting of two monoculars with identical optical
terrains and functions (Fig.1-6). Each monocular has an objective
lens, an image intensifier assembly and an eyepiece lens.
The objective lens collects the ambient light reflected from the
scene by the moon, stars, or night sky glow, inverts the image
and then focuses the image on the image intensifier. Inside the
image intensifier, a photocathode converts the light into
electrons; a micro channel plate amplifies the electrons image
resulting in the electron striking a phosphor screen.
The phosphor screen creates a visible image, which in turn is re-
inverted by fiber optics and transmits to the eyepiece, where the
operator can see the intensified image in its proper 1:1
perspective (unity magnification).




                               12
1.6 ELECTRICAL FUNCTIONS

1.6.1 Power source
The system is powered by two 1.5V alkaline or lithium
replaceable batteries (see Fig.1-7), inserted in power pack.

1.6.2 Electrical function.
Power from the batteries is supplied to the components through
the power pack's 3-positions (ON-OFF-ON) power switch as
follows. In either of ON-positions - power is drawn from the
appropriate battery compartment to energize the binocular.
When the voltage drops to approx. 2.1 Vdc, a low-battery
indicator at the base of the mount assembly blinks, indicating
approx. 30 minutes of operating time left on that battery
compartment.

In OFF-position - the system is not energized from either battery
compartment. With the switch in either of the ON-positions,
power from the battery compartment is applied through the
power cable, through the matching contacts in the mount to the
matching contacts inside the monocular onto the image
intensifier assembly (Fig.1-7).




                                13
1.6.3 Electronic circuit
The electronic circuit regulates the direct current voltage from
the batteries to the image intensifier assemblies, as required. It
also monitors the output voltage of the batteries and turns on a
low-battery indicator when the battery's life is approximately 30
minutes (2.1 Vdc).

                        Figure 1-7. NVS 6 electrical diagram



1.6.4 Image intensifier's power supply function
The power supply inside the image intensifier assembly (refer to
Fig.1-6) converts the 3.0 volts from the power pack to the
applicable voltages, which provide the optimal conditions for
operating the image intensifier. The power supply also provides
automatic brightness control (ABC) and bright source protection
(BSP) under high light conditions.

                                                       14
The ABC automatically reduces the voltages to the micro
channel plate (MCP) to keep the image intensifier's brightness
within a set limit. The effect of this function may be seen when
rapidly changing from low-light to high-light conditions, the
image gets brighter and then after a short delay, dims slightly to a
constant level.

The BSP function reduces the voltage to the photocathode when
the goggles are exposed to bright light sources.

The BSP feature protects the image intensifier from damage and
enhances its life; however, it also has the effect to lowering
resolution. Therefore, under bright conditions, when you would
not, formally, use the goggles, the image produced is not sharp.


1.6.5 Low-battery indicator
Electrical power for the low-battery indicator is drawn from
either compartment, whichever has the high voltage. When
activated, the low-battery indicator light blinks ON and OFF.

                             NOTE
   Make sure to use fresh (no time) batteries before beginning
    a mission. Some batteries that have been used, and still
   have many hours of life remaining, can be used depending
                       on unit procedures.
                                   25
2.3.2 Low Battery indicator check.

At the base of the NVS 6 mount is a red light-emitting diode
(LED) that comes on or blinks at a steady rate when battery
voltage is low (see Fig.2-4). To make sure this indicator works,
perform the following check. With good batteries installed in
both compartments of the power pack, open one of the battery
compartment and pull the cartridge part way out, to make sure
you break the electrical contact.
                             NOTE
     The low-battery indicator must be checked without the
  binocular attached to the mount or in the flipped-up position

Turn the power switch ON to the side where the battery
compartment is open. The Low-battery indicator should come on
or blink.
                          WARNING
     If eyeglasses are worn, the upper rims of the eyeglasses
              can obscure the low-battery indicator.

Return the switch to the OFF (middle) position, return the
cartridge to its initial position and close the battery compartment.

Repeat the same procedure for the second ON position of the
power switch.

If the low-battery indicator does not respond as required replace
the batteries, which are in closed compartment, with fresh ones
and try again. Make sure the power cable is properly connected.
If the indicator still does not function, return the NVS 6 with its
power pack and mount to the maintainer.



2.3.3 Attaching the Binocular to the Mount

A. Make sure the power switch is turned off. Hold the binocular
   with both hands with the eyepieces facing you, and slide the
   spring-loaded ball bearings into the channels of the mount
   until they lock in place.

B. Press the lock release button (see Figure 2-6) and rotate the
   binocular to the up and lock position.

C. Press the lock-release button and ensure it locks properly.

2.4 OPERATING PROCEDURES

2.4.1 Setting the controls and adjustments

The NVS 6 is designed to adjust for differences in head shape
and correct for most differences in eyesight.


                           NOTE
Although the NVS 6 is designed to be used without eyeglasses, if
eyeglasses are needed to read the aircraft instruments and the
eyeglass lenses will fit within the eye relief distance of the
binoculars’ eyepiece, eyeglasses can and should be worn.


                       WARNING
If eyeglasses are worn, the eyeglasses upper rim can obscure the
low-battery indicator.




                               29
                            NOTE
Before using the NVS 6 for flight operations, be sure to check
out the system's operation. Perform the checkout under darkened
conditions.
Use the following operating procedures for check out. If a failure
occurs, refer to the troubleshooting procedures in Chapter 3,
Section II. If the problem persists, the system must be returned to
the maintainer.

Make sure the batteries are installed as described in paragraph
2.3.1. Remove the lens caps. Turn the power switch initially to
one of the ON position. A green glow will appear in each
eyepiece (after a slight delay).


                            NOTE
If a red light appears at the base of the NVS 6 mount, the
batteries in that compartment are low and need to be replaced.
Switch to the other battery compartment and make sure those
batteries are good.

Turn the vertical adjustment knob (see Fig.2-7) to center the
eyepieces in from of your eyes. Minor readjustment may be
needed after adjusting the tilt lever.


                                30
                            NOTE

If the NVS 6 eyepieces are not properly aligned with the eyes,
optimal resolution will not be achieved. Proper alignment of the
eyepieces is achieved when the distance between the monocular
matches the distance between your pupils and the line of sigt is
the same as the vertical angle of the binocular.When all the
eyepiece adjustments (eye-span, vertical and tilt) are properly set,
the edges of the images in both monoculars will be clear.




                                31
                         CAUTION
Do not attempt to adjust the tilt angle of the binoculars by
pushing or pulling the monocular up and down as this will
damage the adjustment mechanism. Use only the tilt lever to
make tilt angle adjustments.
Move the tilt lever (see Figure 2-8) up or down to obtain the
optimum line-of-sight view. If the upper or lower edges of the
image areas are blurred, adjust both the vertical adjustment knob
and the tilt lever until the blurred edge is removed and an optimal
line of sight is achieved.




Turn the fore-and-aft adjustment knob (see Figure 2-9) to move
the monocular away from the eyes as far as possible without
losing the field of view. This makes edge clarity easier to judge.
You may use the fore-and-aft scale to preset this adjustment.




                                32
                         CAUTION
Do not attempt to adjust the eye-span distance by pulling the
monocular away from each other or pushing them together.
Using force on the monocular to make this adjustment will
damage the adjusting mechanism inside the adjustment shelf.

Use only the eye-span knob(s) to adjust the eye-span distance.

If your eye-span distance has measured prior to mounting the
binocular, turn the eye-span knobs(s) (See Figure 2-10) to set this
value on the scale.

If not move the binoculars closer together or further apart to
adjust the eye-span distance for the proper spacing between your
eyes.

When properly adjusted, the edges of the images in both
monocular will be clear and the resultant binocular view will
appear as a single circle or as two circles, overlapped and slightly
displaced laterally.




                                33
                  Figure 2-10 eye-spam knobs



Now, turn the fore-and –aft adjustment knob to move the
monocular closer to the eyes as desired for individual preference
without your eyelashes touching the eyepiece lenses. A 25mm
eye relief distance provides the optimal field of view for the
larger 25mm eyepieces.

3.3 Maintenance procedures

Operator maintenance of the NVS 6 is limited to cleaning the
system as follows:


                         CAUTION

The binocular is a precision electro-optical instrument and must
be handled with care.

Do not scratch or touch the external lens surfaces.

Do not use abrasive materials to clean the gold-plated electrical
contacts.

Gently brush off any dirt using only a soft, lint-free cloth.
Moisten the cloth with fresh water and gently wipe the external
surfaces (except lenses) so they are free of foreign material.
With another dry, clean, soft lint-free cloth, dry any wet surfaces
(except lenses).
Using lens paper, carefully remove all loose dirt from the lenses.
Dampen a folded lens paper with clean water and lightly and
slowly wipe the lenses. After one straight stoke, discard the lens
paper. Repeat this step until the glass surfaces are clean.
