USING INFRARED ILLUMINATOR:

Your night vision viewer is equipped with a built-in powerful Infrared

illuminator light (10). This light operates in a spectrum, which is normally

invisible to a human eye, however with the help of the CCD, located inside

the unit, you will see a beam of light when looking though the ocular lens.

Since the CCD does not actively amplify the available light, you will need to

utilize the IR illuminator often in the nighttime conditions.

To turn the Infrared illuminator ON, press the Infrared illuminator button (4).

The Infrared illuminator has 4 power levels. Please note that to turn the IR

illuminator OFF you must first go through all the power levels. For example –

if you just pressed the Infrared illuminator button once, you are on level 1

and need to press the button 4 more times to turn the IR off.

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.

TROUBLESHOOTING:

1. Unit does not turn on and the light indicator is off:

a) please check if the batteries are inserted correctly

b) please make sure the batteries are fresh

2. The light indicator is working, but you cannot see the image:

a) you may be turning the unit on in a dark area with the lens

cover still on the unit

b) You may need to turn on the infrared light

3. Unable to obtain sharp and clear image:

a) you may need to repeat the process of rotating the ocular

and objective lens several times until you get a good feel of it
