CAUTION:
Before removing the objective lens cap, verify that the photoreceiver is open.
4. Verify that there are no bright light sources in the CO-LR’s field of view. Turn the device ON. After a
slight delay, a green glow will appear in the day scope’s output lens.
CAUTION:
Avoid exposing the device to bright light sources such as firelight, headlights, searchlights, etc.,
as these can damage the CO-LR.
5. To operate the CO-LR in short-time activation mode, turn the switch to the STB position. To activate
the CO-LR, press and hold the remote control button. Release the remote control button to deacti-
vate the CO-LR.
6. Observe the scene. Adjust the focus by rotating the CO-LR focus knob until the image becomes clear
and sharp.
7. Adjust the image contrast by rotating the CO-LR gain control knob (CO-LR MG version).
8. If the day scope includes a focusing ring (i.e., parallax adjustment knob), adjust the focus for a paral-
lax-free image.
9. If necessary, turn on the day scope’s reticle illumination and adjust the reticle brightness.
CAUTION:
Do not leave the CO-LR activated if it is not being used.
NOTE:
Automatic interrupting time is 120 minutes. To resume operation, you will need to restart the
CO-LR.
3.3.2 OPERATING IR850
Use the IR850 in poor light conditions or complete darkness.
CAUTION:
When operating the device in extremely dark conditions, the light from the unit’s IR illuminator
will be invisible to the naked eye. However, the light can be detected by other NVDs.
NOTE:
Do not leave the IR850 activated when the device is not in use.
1. After examining a scene with the CO-LR, turn on the IR850.
2. To change the radiated power level, turn the power switch to one of the spots in between the two
OFF positions.
3. To adjust IR beam divergence, turn the lens.
4. To adjust the IR spot position in the field of view, loosen the clamp screw and tilt the IR850 as re-
quired in the spherical clamp hinge. Tighten the screw using a 2.5mm hex key.
