Safety
• An internal component within the image intensier tube contains toxic materials. During normal
operation, the operator will never come into contact with this component. However, if the tube
is damaged or broken, avoid inhalation or ingestion of the phosphor screen materials, and avoid
contact with open wounds. If the toxic material comes into contact with your skin, wash the aected
area with soap and water. If any material is swallowed, drink large quantities of water, induce
vomiting and seek medical assistance as soon as possible.
• The objective protective cover must always be tted when the night vision goggle is not in use.
Damage to the image intensier can occur if subjected to a strong light source such as daylight for
extended periods, even when power is switched o.
• Never point the PD-PRO-16B towards a bright light source such as the sun. City lights, car lights or
any brightly reecting object will not damage auto-gated tubes.
• Always remove the battery aer use and before repackaging.
• Dry the PD-PRO-16B completely before replacing it in the transit/carrying case.
• Take care when using the ‘‘IR" position ‘3’ of the operation switch an IR light is beaming around,
which can easily be detected by observers and bright light is shining out of the eyepiece, if not
covered.
• For underwater operations, use only the PD-PRO-16B-SUB, which is specially designed to withstand
depths of up to 20m and equipped with Plano-Plano windows.

General Description
1. Scope of Manual
This manual provides description, operating instructions and eld maintenance procedures for the
PD-PRO-16B Night Vision Binocular.
This manual is intended to help you operate and properly maintain the device and promote trouble-free
and ecient operation.
2. PD-PRO-16B Night Vision Binocular
CAUTION
The PD-PRO-16B is a precision electro-optical device. HANDLE IT WITH CARE!
2.1. General Description
The PD-PRO-16B(see Figure 1 and Figure 2) is a lightweight, ruggedized, metallic alloy night vision
BINOCULAR system. It oers a high resolution and clear bright image in a lightweight conguration.
The PD-PRO-16B operation is passive; the light available at the scene is electronically intensied so that
targets can be observed without articial illumination.
The PD-PRO-16B provides a stereoscopic vision to facilitate spatial vision, to drive, measure distances, etc.
The PD-PRO-16B is equipped with a built-in Infra-Red (IR) light, which gives additional close-range
covert illumination.
WARNING
When the IR light is activated, the emitted light can be detected by other image intensifying equipment.
The PD-PRO-16B employs a pair advanced Photonic image intensier tubes characterized by high
resolution and a clear, bright image. 4G auto-gated tubes are the standard conguration.
The PD-PRO-16B is powered by a single “AA” 1.5V, alkaline or lithium battery, or with an external battery
pack with capacity for two alkaline batteries “AA” 1.5V
The system operates under every ambient temperature from -40ºC to +55ºC.
The PD-PRO-16B includes LOW BAT indicator (LED green) in the top of eld of view of right arm, and
IR activation indicator (LED red) in the top of eld of view le arm that providing indications to operator
about state of the system.
The PD-PRO-16B is small and light enough to be hand-held, head mounted or helmet-mounted.

2.2.1. Operation Switch
A three-position rotary switch controls the operation of the MINIMUS-BINO.
WARNING
The IR position is very dangerous when used in the eld, since you will be visible to external observers using
image intensied equipment.
Operation switch of the PD-PRO-16B
The Operation switch of the PD-PRO-16B has three dierent positions:
Position 1:“OFF/M”. The device is disconnected and turns ON each arm of the BINOCULAR when
attached to the helmet mount or head mount and each arm is aligned with the eye of the operator.
When the PD-PRO-16B is ipped to side, the equipment disconnects automatically, preventing the
operator from emitting uncontrolled light that can be detected by the enemy. When reattached to the
helmet mount and aligned with the operator’s eye, the equipment restarts automatically, without need
to restart the ON/OFF switch.
WARNING
Before ipping the goggle into the up position, ensure each channel is rotated up to obtain the ultra-low prole
over the helmet.
Position 2: "ON". In this position the device is on when each arm is aligned with the eye of the operator.
This position activates the PD-PRO-16B for the use in manual mode, as observation binocular; the main
magnetic sensor is disabled.
Position 3: "IR”. In this position the system works like 2 position and a short-range IR illuminator
switching on. This position has two modes, instantaneous or continuous, for instantaneous mode turn
the knob to position 3 and keeps it clamped, when you release it, automatically will return to position 2.
To keep the IR illuminator continuous; pull the knob slightly outwards and then turn it to the position 3.
Night Vision
p. 8

WARNING
*IMPORTANT NOTE FOR OPERATOR SAFETY*
The use of the IR illuminator in open spaces makes the operator visible for outside observers with night
vision. We recommend using it only in conned spaces or extreme situations.
2.2.2. Objective Focus
The objective focus allows adjusting the focus from 15 cm to innity by turning the objective lens.
2.2.3. Diopter Ring
The PD-PRO-16B eyepiece enables diopter adjustment to suit dierent user eyesight, by means of the
diopter ring. It is attached to the eyepiece and provides continuous adjustment from -6 to +2 diopters.
2.2.4. IR LED Illuminator
The PD-PRO-16B is equipped with a built-in IR 935 nm diode (almost invisible for Gen 3 IIT), which gives
additional close-range covert illumination. The illuminator is activated by setting the operating switch to
IR position. A red indicator is displayed in the eld of view indicating that the IR illuminator is active.
2.2.5. Battery Compartment
The PD-PRO-16B battery compartment accepts a single “AA” size battery 1.5 alkaline or lithium and
provides inverse polarity protection.
2.2.6. Mounting Recess
The recess is the mounting surface between the PD-PRO-16M and the helmet mount or head mount.
2.2.7. Neck Cord (optional)
The PD-PRO-16B can be provided with a neck cord for user’s convenience. The type of neck cord can be
suited to customer’s requirements.
2.2.8. Operating Principle
The PD-PRO-16B operation principle is depicted in Figure 3 and is the same for boot goggle arms. Light
entering the objective lens is focused onto the image intensier. The image intensier (2) receives the
optical image from the objective lens (1) in the form of light energy, focused onto the photo cathode (4).
The photocathode is a light-sensitive surface, when light hits the surface it emits electrons.
The optical image is transformed into an electronic one, intensied by a micro-channel plate, and
projected onto the phosphor screen at the rear of the image intensier. This can then be seen through
the eyepiece (3).
The PD-PRO-16B uses 4G 16mm high performance tubes with green or white phosphor, characterized
by low weight, high gain, reduced halo and reduced blooming eect, which normally occurs when
viewing a bright light source.
Figure 3 MINUMUS-BINO Operating Principle
p. 9

The tube also contains Automatic Brightness Control (ABC) and Bright Source Protection (BSP) and
Auto Gated power supply, that gives a steady state of screen brightness under varying light conditions
and high resolution, including conditions normally too bright for a night vision device.

Operation
8. General
This chapter provides operating instructions for the PD-PRO-16B.
CAUTION
The PD-PRO-16B is a precision electro-optical device - handle it with care!
9. Safety
An internal component within the image intensier tube contains toxic materials. During normal
operation, the operator will never come into contact with this component. However, if the tube is
damaged or broken, avoid inhalation or ingestion of the phosphor screen materials, and avoid contact
with open wounds.
a. If the toxic material comes into contact with your skin, wash the aected area with
soap and water. If any material is swallowed, drink large quantities of water, induce
vomiting and seek medical assistance as soon as possible.
b. The objective protective cover must be tted at all times when the night vision goggle is
not in use. Damage to the image intensier can occur if it is pointed to a strong
light source such as daylight for extended periods, even when power is switched o.
c. Never point the night vision goggle towards the sun, even when shut o and with an
objective cover with pinhole. The center of the photocathode can be damaged. When
training at daylight a totally shuttered objective cover or a neutral density lter must be
used. A searchlight, a camera ash or any brightly reecting object, at distances of
more than 5 meter will not damage auto-gated tubes. Never point a visible or IR laser
towards eyepiece or objective as the tube will be damaged permanently.
d. Always remove the battery aer using and before repackaging, to avoid acid leakage due
to defective battery and permanent damage to the electronic board of NVLS EVO.
e. Rinse thoroughly in tap water aer immersion in sea water to prevent drying of salt deposits.
f. Dry the night vision goggle completely before replacing it in the tactical bag or hard-shell case.
g. Take care when using the V and IR positions of the operation switch. In V position bright
light is shining out of the eyepiece, if not covered. In IR position IR light is beaming
around, which can easily be detected by enemy forces and bright light is shining out of
the eyepiece, if not covered.
10. Battery Installation

b. Disconnect the neck cord from the anchor point on clothing or webbing.
c. Make sure that the objective protective cover is in position.
d. Press and hold the NVLS-24 release button on the mounting adapter.
e. Pull the PD-PRO-16B o the dovetail of the adapter assembly.
f. Loosen all straps and unbuckle the chin support.
g. Remove the head mount over your head.
h. Remove the battery from the PD-PRO-16B.
16. Operation at Low Temperature
At very low temperature (below zero) it can require more eort to operate the PD-PRO-16B controls
than in warmer conditions. This is normal. Do not attempt to force the movement of controls as this can
damage the working parts.
The capacity of the battery is reduced at low temperatures. This reduction in battery life is normal and
battery depletion will increase as the temperature decreases.
17. Operation at High Temperature
The PD-PRO-16B can be operated up to 55˚C, but wherever possible protect the battery from excessive heat.
The PD-PRO-16B can be subjected to sudden changes in temperature. But if the PD-PRO-16B is
moved from a cold area (A/C acclimatized) into an area with a much higher temperature and humidity,
condensation can occur on the optical surfaces.
18. Operation in Humid or Dusty Conditions
In humid or dusty conditions, extra care must be taken to keep all surfaces (particularly the optical
surfaces) clean at all times.
When using for diving the sacricial at-at lenses must be rmly attached to objective and eyepiece.
Adjust eyepiece diopter and focusing ring at 1-meter depth.
Aer immersion in salt water, all elements of the goggle must be cleaned with fresh water for
dissolving salts and dried completely with a clean cloth. Salt will corrode any material over a
medium or long-term duration. This will particularly impact the Magnesium variant of the PD-PRO-16B.
