USING INFRARED ILLUMINATOR:
Your night vision binocular is equipped with a built-in
Infrared illuminator light (2). This light operates in a
spectrum, which is normally invisible to a human eye,
however with the help of the tube, located inside the
unit, you will see a beam of light when looking though
the ocular lens. This Infrared light is here to assist
you in especially dark conditions, where there is not
enough light for the tube to amplify.
To turn the Infrared illuminator ON, press the Infrared
illuminator button (4). To turn the infrared light off,
press the same button again.
When using the infrared illuminator it is important to
remember that like a flashlight, it is brightest when
used in short distances. As the distance increases, the
intensity of the infrared light fades away.
Please note that the infrared illuminator has a focusing
feature, which allows you to either spread the infrared
light beam for better viewing in the short distances, or
focus the beam in the center, which increases the
effective viewing distance. For viewing in the
distances over 50m you may purchase an extended
range illuminator (LN-EIR1, or LN-ELIR1) by asking
your dealer, or e-mailing us at:
(please indicate the model number of the binocular
(LN-PB3)). The extended range IR illuminator is
installed on top of the unit by removing the Sliding
Bracket (8).
