3. SAFETY PRECAUTIONS

The following general safety precautions supplement the
specific WARNINGs, CAUTIONs and NOTEs that appear
elsewhere in this manual.

3.1

Batteries . The Clip-On Night Vision Device – Thermal
(CNVD-T) is powered by four lithium DL123A batteries. The
following safety precautions apply when handling lithium
batteries:

• Do not short circuit, puncture, incinerate, or
disassemble.

• Do not attempt to recharge.

• Prior to use, inspect all batteries for cracks, dents,

leakage, or bulging. Never install a defective battery
in the CNVD-T.

WARNING..

Do not use the CNVD-T with a mix of old and new
batteries, or batteries of different brands.

CAUTION..

Lithium batteries can explode or cause burns if
disassembled, shorted, recharged, 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.

ii

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-T.

WARNING..

Use of off-brand batteries poses a risk of fire or
explosion. Ensure that only 3V lithium batteries
produced by well-known battery manufacturers
such as Duracell®, Rayovac®, or Panasonic® are
installed in the CNVD-T. These batteries are
specifically designed for use in high performance,
high-drain devices, and contain built-in fault and
heat protection features.

CAUTION..

Do not ship or store the CNVD-T with batteries
installed.

3.2

Weapons Safety

. The CNVD-T is designed to be used
with destructive weapon systems. Improper operation or
misuse of the CNVD-T 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.

iii

WARNING..

Remove the CNVD-T from the weapon before
inspecting, cleaning, or performing other
maintenance functions.

3.3

Operation and Maintenance

.

CAUTION..

Use of acetone or gun cleaning agents containing
perchloroethylene or methylene chloride may
permanently damage the CNVD-T system.

CAUTION..

Pointing the CNVD-T directly at the sun without
the lens cover installed (and closed) may
permanently damage the thermal assembly.

1.4 PURPOSE OF EQUIPMENT

The CNVD-T is a handheld or weapon-mounted thermal
imaging device that allows for observation, target
identification, and passive target acquisition during the day or
in adverse conditions such as light rain, light snow, dry
smoke, and low light to total darkness.

1.6 SYSTEM DESCRIPTION

The CNVD-T is a battery operated, handheld or weapon­mounted, thermal imaging device. It allows for observation,
target identification, and target acquisition during the day or
in adverse conditions such as light rain, light 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 CNVD-T detects and displays available thermal
signatures to provide rapid cueing to the operator of potential
targets or danger. The sight is passive and does not emit
visible or infrared light (except from the eyepiece) that can
be detected by the enemy.

The CNVD-T can be mounted to weapons equipped with a
MIL-STD-1913 rail. It may also be used in conjunction with
other optical and red dot sights.

It is a ruggedized system designed for operation in battlefield
environments.
