SAFETY PRECAUTIONS

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

Laser Radiation

Depending on the particular model, the Weapon Mounted Mini Thermal Monocular (WTM) is equipped with either a Visible or Infrared (IR) Laser Pointer. The IR laser is invisible to the naked eye. Regardless of model, the following general safety precautions apply at all times:

• 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 individuals’

eyes.

Nominal Ocular Hazard Distances (NOHD) for safe operation and required Optical Densities (OD) are listed in Table i-1.

Table i-1 Laser Safety Parameters

Laser

Viewing without magnifying optics.

Viewing with 7x magnifying optics.

WARNING

Exposure to the WTM’s laser beam inside the NOHDs listed in Table i-1 can cause irreversible damage to the human eye.

WARNING

IR lasers are detectable by an enemy using night vision devices. Detection is easier in smoky, foggy, or rainy conditions. To reduce the risk of detection by an enemy using night vision devices, avoid prolonged activation of the WTM’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 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 WTM.

WARNING

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

iii

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.

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 WTM.

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 WTM. These batteries are specifically designed for use in high performance, high-drain devices, and contain built-in fault and heat protection features.

WARNING

Remove the WTM from the weapon before inspecting, cleaning, or performing other maintenance functions on the WTM.

CAUTION

Do not ship or store the WTM with batteries installed.

CAUTION

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

CAUTION

Pointing the WTM directly at the sun without the lens cover installed may permanently damage the thermal assembly.

EQUIPMENT DESCRIPTION

1.6 SYSTEM DESCRIPTION

The WTM is a battery operated, thermal imaging device with an integrated Laser Pointer (IR or Visible) and digital camera. It may be mounted to a standard tripod, an AN/PVS-7 / PVS-14 helmet assembly, or to any weapon equipped with a Picatinny (MIL-STD-1913) or Weaver rail.

The thermal imaging capability of the WTM allows for observation and target identification under adverse conditions including light rain, smoke, light snow, and low light to total darkness. It will not allow the user to see through glass, water, or heavy rain / snow.

Models equipped with a Visible Laser Pointer provide for target acquisition in low light conditions without the need for night vision devices. Models equipped with an IR Laser Pointer provide for target acquisition in low light or complete darkness when used in conjunction with night vision devices.

With the integrated camera, the WTM allows for acquisition, storage, download, and recall of viewed thermal images. Thermal images may also be transferred to a personal computer.

The WTM is a ruggedized system designed for operation in battlefield environments.
