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
1
Viewing without magnifying optics.
2
Viewing with 7x magnifying optics.
ii
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.
iv
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.
