InfRA-RED IllumInAToR

Infrared illuminators, or IR illuminators, are common for night vision. The IR light greatly
enhances the performance of the NVB8 while remaining almost totally invisible to the
naked eye.
The NVB8 have a built-in IR with indicator
"ON" within the FOV. To turn the IR on,
hold the button pressed for more than 1.5
sec. It is important to remember that the IR
illuminator is but an infrared light source,
and like any light source, it may loose its
effectiveness over a great distance.
To turn the IR off, again hold the button
pressed for more than 1.5 sec.
NOTE: The IR will automatically turn off when the unit's power is off.
