elsewhere in this manual.
WARNING
The Clip-On Night Vision Device – Thermal 2
(CNVD-T2) emits invisible laser radiation in the
form of an Infrared (I R) Laser Pointer designated
Safety Class 1. Nominal Ocular Hazard Distances
(NOHD) for safe operation are listed in Table i-1.

WARNING
• Do not stare into the laser beam.
• Do not look into the laser beam through binoculars
or telescopes.
• Do not point the laser beam at mirror-like surfaces.
• Do not shine the laser beam into another indivi dual s’
eyes.
ii
WARNING
IR lasers are detectable by an enem y using night
vision devices. Detection is easier in smoky,
foggy, or rainy conditions. To reduce the ri sk of
detection by an enemy using night vision devices,
avoid prolonged activation of the CNVD-T2’s IR
Laser Pointer.
WARNING
Emission of stray light from the eyepiece (even
with the eyecup installed) may be detectable by
the enemy.
WARNING
Do not touch, ingest, or inhale particles or
fragments of a broken thermal objective lens.
Thermal lenses contain material that may cause
irritation to eyes, skin, upper and lower respirat ory
tracts, or gastrointestinal t ract. If contacted, flush
eyes or skin with large amounts of water. If
ingested, DO NOT induce vomiting. Rinse m outh
with water and give victim 2-4 cupf uls of milk or
water. Fragments of the lens may be sharp
enough to cut personnel if touched.
WARNING
Activating Z OOM 2X when the CNVD-T2 is used
in-line with other optical sights may introduce an
error in the aiming function of those devices.
WARNING
Do not use the CNVD-T2 with a mix of old and
new batteries, or batteries of different brands.
iii
WARNING
• Do not short circuit, puncture, incinerate, or
disassemble batt eri es.
• Do not attempt to recharge batteries.
• Prior to use, inspect all batteries for cracks, dents,
leakage, or bulging. Never install a defective battery
in the CNVD-T2.
WARNING
Lithium batteries can explode or cause burns if
disassembled, shorted, recharged, or exposed to
water, fire, or high temperatures (above 100°C or
212°F). Do not place loose batteries in a pocket
or other container containing metal objects. Do
not store batteries with hazardous or combustible
materials. Store in a cool, dry, ventilated area.
WARNING
Use of off-brand batteries poses a risk of fire or
explosion. Ensure that only batteries produced by
a well-known battery m anufacturer are installed in
the CNVD-T2. These batteries are specifically
designed for use in high performanc e, high-drain
devices, and contain built-in fault and heat
protection features.
WARNING
Use of incorrect batteries poses a risk of fire or
explosion. Be aware that batteries do exist with
similar physical characteristics to the DL123A
battery, but with a different voltage and/ or polarity
path. Ensure that only 3V lithium batteries with a
raised positive (+) terminal are installed in the
CNVD-T2.
iv
WARNING
The CNVD-T2 is designed to be used with
destructive weapon systems. Improper operation
or misuse of the CNVD-T2 with these weapon
systems could lead to personal injury or death of
either the operator or other persons within
weapons range. Safe firearms handling
procedures must be practiced at all times.
WARNING
Remove the CNVD-T2 from the weapon before
inspecting, cleaning, or performing other
maintenance functions.
WARNING
Isopropyl alcohol is flammable and toxic. To avoid
injury, keep away from open fire and use in a well
ventilated area.
CAUTION
Use of acetone or gun cleaning agents containing
perchloroethylene or methylene chloride may
permanently damage the CNVD-T2 system.
CAUTION
Pointing the CNVD-T2 at the sun (even when
powered off) without the lens cover installed may
damage internal imaging components.
CAUTION
Do not ship or store the CNVD-T2 with batteries
installed.

1.6 SYSTEM DESCRIPTION
The CNVD-T2 is a battery operated, weapon-mounted,
thermal imaging device with an integrated IR Laser Pointer
and digital camera. It may be used as a handheld device,
mounted to a weapon in a stand-alone configuration, or used
in-line with a magnified day optic.
The thermal imaging capability of the CNVD-T2 allows for
observation and target identification under adverse
conditions such as light rain or snow, dry smoke, and low
light to total darkness. The unit will not allow the user to see
through glass, water, or heavy rain / snow.
The integrated Laser Pointer provides a means of marking
potential targets in low light or complete darkness for handoff
to individuals using night vision devices.
With the integrated digital camera, the CNVD-T2 allows for
acquisition, storage, download, and recall of viewed thermal
images. Thermal images may also be transferred to a
personal computer (PC) using the Image Adapter Cable.
The CNVD-T2 can be mounted to weapons equipped with a
MIL-STD-1913 rail.
It is a ruggedized system designed for operation in battlefield
environments.
