CAUTION:
SAFETY SUMMARY
STUDY CAREFULLY THIS MANUAL BEFORE TURNING ON
AND OPERATING THIS PRODUCT.
CAUTIONS
The TTWS Series Thermal Digital Riflescopes are precision
electro-optical instruments and requires careful handling. To pro-
vide safe use of the systems the following instructions should be
observed:
• Do not dismantle the device.
• Keep the device clean; protect it from moisture, sharp tem-
perature drops and shocks.
• Be careful not to touch the glass surfaces. If you put fin-
ger-prints on, or contaminate the glass surfaces, use only
clean and soft materials to clean it.
• Do not leave the device in on position during stops in opera-
tion.
• Remove the batteries from the device for the period of storage.

b
WARNING
Do not permanently attach the scope to dynamic-mount applica-
tions that continuously transmit vibration (such as on vehicles or
heavy machinery).
WARNING
Do not point the scope directly at any high-intensity objects that you
must not view with your eyes (such as the sun or a welding arc). If
you do, you will damage the scope.
WARNING
Operating TTWS Series outside of its specified operating tempera-
ture range or voltage range can cause permanent damage and will
void the warranty.
WARNING
Use the power button to turn the scope off before you remove power
(remove batteries or disconnect external power supply).
WARNING
TTWS Series operates over a wide operating temperature range
(-20°C to +60°C). Not all lithium batteries are specified over this
same temperature span. Check the manufacturer’s specifications
of your selected battery to verify the valid temperature range.
WARNING
Do not use any battery other than a CR-123A lithium battery. DO
NOT use any battery(ies) providing a (combined) voltage greater
than 12.0 volts.
WARNING
Do not install batteries of different types (lithium with lithium-ion
rechargeable). All batteries must be of the same type.
WARNING
Do not replace batteries in a possibly explosive environment, such
as a gas station (or any place where you must turn off your vehicle
engine). If you do, sparks can cause an explosion.

c
WARNING
Remove the batteries before you store the riflescopes for extended
periods (2 weeks or more).
WARNING
Do not carry batteries in pockets containing metal objects such as
coins, keys, etc. Metal objects can cause the batteries to short cir-
cuit and become very hot. In the case of lithium batteries, a short
circuit could cause them to explode.
WARNING
Observe battery manufacturer’s guidelines for safe handling and
proper disposal of batteries.
EQUIPMENT LIMITATIONS
• The TTWS Series detector spectral band (7 to 14 mkm) pro-
vides a better penetration through smoke, smog, dust, water
vapor etc.
• Infrared radiation does not travel through glass and therefore
the scope does not sense objects if they are behind a glass
window.

1.2. DESCRIPTION AND DATA
1.2.1. DESCRIPTION
a. Purpose
The TTWS Series Thermal Digital Riflescopes combines the ergo-
nomic features of a handheld and the convenience of weapon
mounting. Based on the proven 324x256 or 336x256 or 640x512
microbolometer core, the TTWS is an ideal product for force pro-

forces providing them the tools they need to be successful in all
field conditions both day and night. Uncooled thermal imaging cuts
through dust, smoke, fog, haze, and other battlefield obscurants. Its
use cannot be detected as it emits no visible light or RF energy and
operates without the use of illuminators or IR lights.

1.2.4. MECHANICAL FUNCTION
The mechanical adjustments of the TTWS sights allow for physi-
cal differences between individual operators using the system. The
scope functions include the Keypad, Output Connector, Eyepiece
Diopter Adjustment Ring, Focusing Ring, Battery Module, Accessory
Rail, and Weapon Mount.The controls are identified in Figure 1.4.

1.2.5. OPTICAL FUNCTION
The optical functions include an objective lens, thermal imaging
detector, display and eyepiece. Infrared energy is emitted propor-
tionally to the temperature of an object. The warmer the object,
the more energy it emits. The infrared energy from the objects is
focused by the optics, onto an infrared detector. The information

1-12
from infrared detector is passed to electronics for image process-
ing. The signal processing circuitry translates the infrared detector
data into an image that can be viewed on the built-in OLED display.
The image is observed through an eyepiece by operator.
1.2.6. ELECTRICAL FUNCTION
The electronic circuit is powered by replaceable four 3V lithium bat-
teries (CR123A). Power from the batteries is supplied to the compo-
nents through the Power button.
