WARNING

Do not permanently attach the camera to dynamic-mount applica­tions that continuously transmit vibration (such as on vehicles or
heavy machinery).

WARNING

Do not point the camera 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 camera.

WARNING

Operating OTS 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 camera off before you remove
power (remove batteries).

WARNING

OTS operates over a wide operating temperature range (-30°C
to +60°C). Not all AA 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 3.0 volts.

WARNING

Do not install batteries of different types (lithium with lithium-ion
rechargeable). All batteries must be of the same type.

WARNING

Always replace ALL 2 batteries. If you install new batteries with
used batteries, the result may be dangerous.

b

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.

WARNING

Remove the batteries before you store the camera 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 OTS 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.

C. FRAME RATE

One of the most important specifications of any thermal imaging
device is frame rate. This refers to the number of frames per sec­ond that can be viewed by the device. The lower the frame rate,
the choppier the motion. Conversely, the higher the frame rate, the
more precise the motion. This is especially critical in weapon scope
applications that require precise and quick acquisition.

Standard professional thermal systems come in 30hz (Fast Imag­ing or FI) while many commercial viewers run at 9hz (Standard Im­aging or SI). In 2012, ATN is proud to offer 60hz (Enhanced Imaging
or EI) options for most of its thermal systems. With Enhanced Im­aging you will never have to worry about hitting behind the moving
target because your skill outpaces the technology in your scope.

1.2.6. OPTICAL FUNCTION

The optical functions include an objective lens, thermal imaging de­tector and eyepiece. Infrared energy is emitted proportionally 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 from infrared detector
is passed to electronics for image processing. 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.

1.2.7. ELECTRICAL FUNCTION

The electronic circuit is powered by replaceable batteries - either
two 3.0 Volt lithium battery (CR123A).

Power from the batteries is supplied to the components through the
OFF-ON switch button.
