ings on the monocular’s body.

OPERATIOn In nIgHTTIME cOnDITIOnS
cAuTIOn:
Avoid exposing the night vision device to bright light sources. Bright light emitted by fires,
automobile headlights, lanterns, projectors, etc. will damage your Avenger.
1) Visually estimate the illuminance level in the viewing area. Operation of the device with the objective
lens cap removed is safe when the illuminance level is less than 1 lux; at an illuminance level of 1 lux,
you will barely be able to read a newspaper, even after your eyes have adapted to the low level of light.
2) Verify that the battery is inserted into the battery compartment in accordance with the polarity
markings on the monocular’s body.
3) Remove the front lens cap.
4) Activate the unit. After a momentary delay, green light indicating correct IIT operation will appear.
