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 attempt 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 performance, high-drain devices, and contain built-in fault and heat protection features.

CAUTION

Do not ship or store the 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 sun without the lens cover installed (and closed) may permanently damage the thermal assembly.

EQUIPMENT DESCRIPTION

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 equipped with a MIL-STD-1913 rail.

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

OPERATING INSTRUCTIONS

SECTION I

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.Objective 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. Before use, inspect all 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

2.2.1 Battery Inspection. Before installation, inspect the batteries for any cracks, dents, leakage, or bulging. Never install a defective battery in the CNVD-T3.

2-1

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.

Figure 2-1 Battery Installation

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 POWER” message appears, the display quality will deteriorate rapidly.
