cAUtion:
• The device is equipped with an infrared LED which is not hazardous to human health. However
do not point the IR illuminator at anyone’s eyes.
• The IR illuminator infrared light will be invisible to the naked eye. The light can, however, be
detected by other night vision devices.
• DO NOT leave the IR illuminator activated in the ON position if it is not being used.
Operate the IR illuminator as follows:
1. Turn on the IR illuminator by rotating the power switch from OFF position.
2. To change the radiated power level, turn the power switch to one of the spots between the two OFF
positions. The brightness levels are marked with dots of increasing size, respective to the four different
output power levels.
3. To adjust IR beam divergence, turn the objective lens of IR illuminator.
4. Adjust the IR spot position in the field of view of the NVD as follows (refer to Figure 5):
a) loosen the screws (A) of the clamp on the IR illuminator mount (using a 2.5 mm hex key);
b) turn on the night vision device and the IR illuminator;
c) carefully move the IR illuminator up and down and side to side while looking through the eye-
piece of your device to, observe the IR spot position relative to the night vision device;
