DIGITAL NIGHT VISION

1. Your night vision viewer operates with batteries. Unlike a daylight

binocular, where you see the image due to light traveling through the
glass and the prisms, the digital night vision device works by projecting
the image onto an LCD screen. While the CCD and the LCD are the
crucial components of your viewer, the optical parts of the unit are also
very important, as they gather the light into the CCD and bring the
projected image from LCD screen to your eye. Since the image is
projected on the screen, just like any TV, it has certain limited resolution,
so your digital night viewer cannot provide the same crystal clear image,
as you see through your daylight binoculars – after all, you are using this
device in the dark environment, where normally your vision would be
very limited.

2. Another important point – your digital night vision viewer has color
image during the day and monochrome (black & white) image during the
night – why? Because color CCD are generally not as light sensitive as
black & white, the color CCD will not be as effective as black & white
during nighttime conditions. The color transition is automatic and you
may notice some image flickering during this transition. This is normal
and does not affect the unit.

3. Your digital viewer is intended for nighttime operation however it is
also possible to use it during daylight hours. Please note that during
daylight you will have to reduce the brightness and contrast levels of the
unit to prevent the image from becoming totally washed out.
