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 pro­vide 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 tem­perature drops and shocks.

• Be careful not to touch the glass surfaces. If you put fin­ger-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 opera­tion.

• Remove the batteries from the device for the period of storage.

CAUTION:

THIS PRODUCT CONTAINS NATURAL RUBBER LATEX

WHICH MAY CAUSE ALLERGIC REACTIONS.

a

WARNING

Do not permanently attach the scope to dynamic-mount applica­tions 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 tempera­ture 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.

b

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 cir­cuit 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) pro­vides 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.

3.2.2. FOCUSING

To focus the scope you need to adjust the diopter first. The scope
has an adjustable eyepiece with a range of +2 to -6 diopter. Simply
turn the diopter clockwise until it stops. Then concentrate on any
object and slowly turn the diopter back counter clockwise until the
grain in the image is sharp. Then rotate the eyecup to accommo­date use over the left or right eye.

The TTWS models have ability to focus either long range or short.
Focus the front lens to rotate it until the image and the grain are
both sharp.
