General information
Night vision products are electro-optical devices which support
vision in conditions of virtually total darkness. This is made possi-
ble by enhancing the residual light present, e.g. from the moon or
stars. Thanks to the integrated infrared lighting, which represents
an external light source, observation is even possible in conditions
of pitch darkness.
Your new device is a professional product, which requires careful
handling and maintenance like every other high performance de-
vice. The technology included in your new night vision device is
specially designed to support observations made under conditions
of darkness. In comparison to binoculars, night vision devices do
not incorporate exceptionally high magnifications, since these often
adversely affect the resolution and the ability to enhance lighting.
Battery installation
Loosen the lock of the battery compartment door (6b) and flip down
the door to open. Insert 3 AA batteries into the container. Please be
careful to ensure the correct polarity (as indicated on the inside of
the battery container lid). To extend the service life of the device,
we recommend that alkaline batteries be used.
Flip up the battery compartment door to close it, hold it firmly and
lock it.
Important!
It is advisable to remove the batteries when the device is not used
for more than 24 hours. This prevents the batteries from leaking
and extends their service life.
Please do not use rechargeable batteries, since the base voltage
they provide is insufficient. We recommend using high performance
type AA 1.5 V alkaline batteries.
Using the device
Remove the lens caps (7). Slide the Power Switch (1) to turn the
device on. Look through the Ocular Lens (3) turn it to focus your
eye piece until the black frame of the screen is sharp.
Line up the device with an object at a distance; turn the Object Lens
(4) to focus your viewing object. You are required to re-focus your
device whenever the distance between the device and your viewing
object changed. While the device is turned on, press the Mode but-
ton (2) briefly to cycle through the operation modes:
