SAFETY SUMMARY
Before operating this product, carefully read and study this Operation and Maintenance Manual.
The PVS-7 is a precision electro-optical instrument, and requires careful handling. To avoid damage to
the equipment or physical harm to the user when operating the PVS-7, follow all WARNINGS, CAUTIONS
and NOTES.
Below you will nd denitions of the following alerts that appear throughout this Manual:
WARN ING — Identies a clear danger to the person operating the equipment.
CAUTION – Identies risk of damage to the equipment.
NOTE – Serves to highlight essential procedures, conditions, and statements, or convey important in-
structional data to the user.
WARNING:
This product contains natural rubber latex which may cause allergic reactions! The FDA
has reported an increase in the number of deaths that are associated with an apparent sensitivity to natural latex proteins. If you are allergic to latex, it is a good idea to learn which products
contain it and strictly avoid exposure to those products.
WARNINGS:
When used in total darkness, the light from the unit’s infrared (IR) illuminator is invisible to •
the unaided eye. However, the light can be detected by other Night Vision Devices (NVD).
To reduce the risk of detection by another NVD, avoid prolonged activation of the IR illumi-•
nat or.
The IR light is more easily detected by an NVD when used in smoke, fog and rain. Avoid pro -•
longed activation of the unit’s IR illuminator in these conditions.
The intensier’s phosphor screen contains toxic materials. Please note the following:•
If the intensier tube breaks, be extremely careful to avoid inhaling the phosphor screen —
material. DO NOT allow the material to come in contact with your mouth, eyes, or any
open wounds on the skin.
If the phosphor screen material comes in contact with your skin, wash it o immediately —
with soap and water.
If you inhale or swallow any phosphor screen material, drink a lot of water, induce vomit- —
ing, and seek medical attention as soon as possible.
The information provided in this manual is for familiarization purposes only; the contents may undergo further
changes with no commitment by Armasight© to notify Customers of any updates.

CAUTION:
The PVS-7 is a precision optical instrument. To prevent damage to the unit, it should always •
be handled carefully.
Do not scratch the external lens surfaces or touch them with your ngers.•
To protect the image intensier, keep the lens cap securely tted over the objective lens •
when the device is not in use, or when it is being used in daylight conditions.
The IR illuminator produces light that is invisible to a naked eye, so that it can be used in con-•
ditions of extreme darkness. However, the IR light can be detected by other NVDs.
Use of rubber eyecups for extended periods of time may cause skin inammation. If any •
symptoms develop, consult a doctor immediately.
NOTES:
Do not test the device in daylight conditions for more than ten (10) minutes, even with the •
daylight lter/ lens cap on.
To protect the device from damage, do not direct it at bright light sources (re, automobile •
headlights, lanterns, etc.).
The purpose of the built-in IR illuminator is to provide additional illumination when neces-•
sary while viewing scenes at close distances (up to 3 meters).
The unit is equipped with an Automatic Shut-o System. When the goggles are removed •
from the head mount or helmet mount while turned on, they will turn o automatically. To
turn the unit on after automatic shut o, you will need to rotate the operation knob to the
OFF position rst and then return it to the ON position.
To avoid physical danger to the user and damage to the equipment, carefully read and un-•
derstand the following equipment limitations:
The equipment requires some ambient light (moonlight, starlight, etc.) to operate. —
Performance of the device in nighttime conditions depends on the level of ambient light —
in the environment. Please remember the following:
The level of ambient light is reduced by the presence of clouds, shade, or objects that •
block natural light (trees, buildings, etc.).
The equipment is less eective when operated in shadows and other darkened areas.•
The equipment is less eective when operated in rain, fog, sleet, snow, dust or smoke.•
The equipment will not “see” through dense smoke.•

DESCRIPTION AND DATA
2.1 SYSTEM DESCRIPTION
The PVS-7 is a hand-held, head-mounted or helmet-mounted night vision system that enables mobility, driving, weapon ring, short-range surveillance, map reading, vehicle maintenance and administering rst aid during operation in both moonlight and starlight. Each unit allows for vertical adjustment
(using the head straps), fore-and-aft adjustment, objective lens focus, eyepiece focus and eye relief
distance adjustment. The goggles are also equipped with an infrared (IR) light-emitting diode (or illuminator) and a low battery LED indicator. The goggles automatically shut o when disconnected
from the head mount or helmet mount, or when ipped up on the helmet mount. A bright light cuto
feature shuts o power to the goggles when they are exposed to excessive levels of light for more than
70 (±30) seconds.
The PVS-7 includes the items shown in Figure 2-1. See Table 2-1, Table 2-2 and Figure 2-1 for Standard
and Optional Equipment.
A. Goggles Assembly. The goggles assembly consists of four primary sub-assemblies; a simple objective lens, a wired housing assembly, an image intensier tube (IIT) assembly (not shown), and a rear
cover assembly. The wired housing assembly contains a built-in battery compartment, attached battery cap and the RESET/ OFF-ON-IR/ PULL switch.
B. Head mount Assembly. The adjustable, cushioned head mount assembly secures the goggles
to the operator’s head, providing hands-free operation and allowing the use of weapons, protective
masks and other devices. The thin brow pad (intended for use with larger heads) comes attached to
the head mount. Thicker, or medium, brow pads (intended for use with smaller heads) are stored in the
carrying case.
C. Carrying Case. The canvas carrying case is provided for transportation and protection of the PVS-7,
head mount assembly, batteries and accessories. Two slide keepers are provided for belt attachment.
A carrying case strap, which can be attached to the two D-rings on the back of the carrying case, is also
included. The case has a zipper closure.
D. Demist Shields. The two demist shields are used to prevent the eyepiece lenses from becoming
fogged.
E. Sacricial Window. A replaceable sacricial window is supplied to protect the objective lens during
operation in adverse conditions.
F. Neck Cord. This additional authorized item can be attached to the compass or 3X magnier lens and
worn by the operator to prevent them from dropping or losing these items.
I. Optional Equipment. Optional equipment includes compass, helmet mount assembly, 3x and 5x
Mil-Spec Magnier Lenses, Long Range Infrared illuminator, Mil-Standard Hard Shipping/Storage Case
and an IR spot/ ood lens.
The PVS-7 may sometimes be supplied in hard shipping and storage case. Batteries may also be stored
in this case.

2.1.2 OPTICAL AND ELECTRICAL FUNCTIONS
The optical functions include an objective lens, image intensier, a collimator lens, and two eyepieces.
The objective lens collects light reected from the moon, stars or other ambient light in the night
sky, and inverts and focuses an image of the scene onto the image intensier. The electrical functions
include the following:
A. Power Source. The electronic circuit is powered by replaceable batteries - either a 3.0 Volt lithium
battery (BA-5567/U) or two AA 1.5 Volt alkaline batteries (BA-3O5S/U).
B. Electrical Principles. Power from the batteries is supplied to the components through the RESET/
OFF-ON-IR/ PULL switch as follows:
RESET/ OFF Position. With the switch in the OFF position, the circuit will not supply energy to the image
intensier or the IR illuminator. You can also turn the switch to this position to reset your device after
automatic shuto or bright light cuto.
ON Position. Energy is drawn from the battery compartment to power the goggles. When the voltage
drops to 2.4 VDC, a low battery indicator will begin to blink on the right side region of the eyepiece,
indicating approximately 30 minutes of remaining operating time.
IR/ PULL Position. Energy is drawn from the battery compartment to power the goggles and IR light
source, and a steady red indicator light will appear in the left side region of the eyepiece. The IR can be
momentarily turned on by turning the switch ON without pulling the knob.
