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 3
(CNVD-T3) is powered by two lithium DL123A batteries.
The following safety precautions apply when handling lithium
batteries:
• Do not short circuit, puncture, incinerate, or
disassemble.
• Do not att em pt to recharge.
• Prior to use, inspect all batteries for cracks, dents,
leakage, or bulging. Never install a defective battery
in the CNVD-T3.
WARNING..
Do not use the CNVD-T3 with a mix of old and new
batteries, or batteries of different brands.
WARNING..
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-T3.
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-T3. These batteries are
specifically designed for use in high perform ance,
high-drain devices, and contain built-in fault and
heat protection features.
CAUTION..
Do not ship or store t he CNVD-T3 with batteries
installed.
3.2
Weapons Safety
. The CNVD-T3 is designed to be used
with destructive weapon systems. Improper operation or
misuse of the CNVD-T3 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-T3 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-T3 system.
CAUTION..
Pointing the CNVD-T3 directly at the s un without
the lens cover installed (and closed) may
permanently damage the thermal assembly.

1.6 SYSTEM DESCRIPTION
The CNVD-T3 is a battery operated, weapon-mounted,
thermal imaging device with an integrated 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-T3 allows for
observation and target identification under adverse
conditions such as light rain or snow, dry smoke, and low
light to total darkness. It has a self-contained, internal
shutter used for calibration. The unit will not allow the user
to see through glass, water, or heavy rain / snow.
With the integrated digital camera, the CNVD-T3 allows for
acquisition, storage, and recall of viewed thermal images.
Thermal images may also be transferred to a personal
computer (PC) using the Image Adapter Cable.
The CNVD-T3 can be mounted to weapons equi pped with a
MIL-STD-1913 rail.
It is a ruggedized system designed for operation in battlefield
environments.

OPERATING INSTRUCTIONS
PREPARATION FOR USE AND INSTALLATION
2.1 PREPARATION FOR USE
2.1.1
Unpacking the Equipment . Before unpacking the
equipment, verify that all major components listed in Table
1—2 are present. Check the CNVD-T3 assembly to ensure
the following additional items are also included:
a. Battery Cap Assembly
b. Video Jack Plug
c. Object i ve Lens Cover (and straps)
d. Objective Lens Protective Ring
If any of the major components or items listed above are
missing, seek guidance from the equipment issuing
authority.
2.1.2
Inspection of the Equipment
pieces of equipment for any damage such as cracks, loose
parts, faulty cables, or other visible defects. If any damage
or defects are noted, seek guidance from the equipment
issuing authority.
2.2 BATTERY HANDLING

2.2.2 Battery Installation
. Proper battery orientation is
clearly marked on the CNVD-T3 housing. Unscrew the
battery cap and install the first DL123A lithium battery. Tilt
the CNVD-T3 to allow the battery to slide into the battery
compartment, thereby providing space to insert the second
battery. Install the second battery, then replace and screw in
the battery cap.

CAUTION..
Do not ship or store the CNVD-T3 with batteries
installed.
2.2.3
Low Battery Power. A low battery message will
appear in the eyepiece display when approximately 20
minutes of continuous operation remain. If the batteries are
not replaced promptly when the “LOW P OWER” message
appears, the display quality will deteriorate rapidly.
