LOW BATTERY AND IR “ON” INDICATORS
Unit “ON” indicator (green color), Low battery indicator “Low Battery” (red light), IR indicator “IR
ON” (yellow color) & high light cut off indicator “Bright Light” (blue color) located in the top portion of
visible field of view of the NVD.
IR Illuminator
NVD is equipped with build in IR light for illumination of close by objects located in front portion of the
body of module. Brightness of the IR light is bright enough to read the map in complete darkness (with
objective lens 25mm/F1.3) it is also allows to conduct small repairs and maintenance work.
Moisture collector
Moisture collector is design to collect moisture inside the NVD during operation. If Moisture collector
is dry the color inside the window is blue. If on the other hand, moisture collector is full of moisture than
the color is pale pink or grey. You can replace Moisture collector cartridge using the key provided with the
unit.
Soft padded carrying case
Carrying case is design to accommodate the unit as well as all accessories that are included in the
standard package . The case is made from nylon with soft padded inserts designed to absorb the shock
of impact as well additional packets for other tools. The case also has adjustable shoulder strap.

POWER SOURCE
Power source for NVD is provided by one Ni-MH power cell voltage 1.2V (
not less 2300 mAh)
type
«ÀÀ» or one Alkaline battery voltage 1.5V type «ÀÀ».
This is enough for continued operation for up to 20 hours at 20°Ñ in observation mode and 6 hour of
operation with IR illuminator turned on. The batteries are easy to replace in any environment and the
construction of battery house is designed so the even if polarities are reversed the unit is protected.
Besides normal operation the NVD is able to use external power supply from any external source
with voltage of 3.5 - 1.5V, as an example the NVD work of a car adapters or CCTV-systems. In order to
use external power source in the battery compartment instead of «ÀÀ» battery you need to instal
external power adapter (optional), which ensures that voltage is stabilized at 1.5V, as well as it protects
from reverse polarities and a transition cycle in the chain of external source range to ± 60V. Adapter is
equipment with low voltage slot type size 5,5/2,1 for continuous power supply.
