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

thermal image may be noticed. In these instances, and
during initial startup, the WTM should be calibrated to
optimize the viewed thermal image.
Calibration is accomplished by simultaneously pressing (and
holding) the UP / DOWN buttons, or via the system menu
(see section 2.16, Calibration (CAL)). Regardless of which
method is used, the objective lens cover must first be placed
over the objective lens. Failure to do so may result in a
distorted picture or the presence of ghost images in the
eyepiece display.
The WTM is equipped with an internal sensor that detects
significant changes in temperature. When this condition
occurs, the message “RECAL” will appear in the eyepiece
display indicating that the operator should calibrate the WTM
as described above.

Retrieving Stored Images
Images stored in the WTM may be downloaded to the Image
Adapter Cable and converted to either a .tiff or .jpeg file
format (depending on model). Once downloaded, images
may then be viewed, saved, edited, and/or deleted by a PC
in the same manner as any files accessed through an
external drive. The Image Adapter Cable can store in
excess of 400 .tiff files. Storage capacity for .jpeg files is
considerably higher.
NOTE
The download process does not remove any of the
raw images from the WTM’s flash memory.
Deleting saved pictures from the WTM must be
accomplished as described in section 2.16,
Review (REV).
1. Plug the Image Adapter Cable into the WTM by aligning
the white dot on the cable plug with the white dot on the
video jack. Push the cable plug into the jack until it locks
into place.
2. Insert the Image Adapter’s Universal Serial Bus (USB)
connector into a free USB port on the computer. The PC
will recognize the Image Adapter as an external hard
drive and will normally open a Windows Explorer dialogue
box to display the contents of the drive.
3. Wait for the LED on the Image Adapter to turn solid
green. Other LED status indicators are described in
Table 2-5.

4. Press the Download Button. This action downloads all
images stored in the WTM’s flash memory, converts them
to .tiff (or .jpeg) format, and saves them to the flash
memory of the Image Adapter Cable. The LED on the
Image Adapter will flash green during this process.
NOTE
The Image Adapter creates a separate folder for
each of the WTM devices it has been connected
to. Initiating the download process from the same
WTM will cause the Adapter to overwrite the
existing folder. Renaming the folder prior to
downloading new images will preserve the content
of the original folder.
5. Wait for the LED on the Image Adapter to return to a
steady green state indicating that the transfer process is
complete. Open or refresh the Windows Explorer
dialogue box to view the contents of the Image Adapter’s
flash memory. Images may then be viewed, saved,
edited, and/or deleted in the same manner as any files
accessed through an external drive.
