CAUTION:
Remember that external light indication is one of the factors which make you detectable. Mask
the LED indicator with the cap, if necessary.
1. Verify that the battery is installed as required.
2. Perform a visual estimation of the illumination level in the viewing area, using the reference data
presented in Appendix A. You can begin operating the CO-MR if the illumination level is less than
1 lx.
3. Remove the objective lens cap and place it over the lens’ housing.
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-MR’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-MR.
5. To operate the CO-MR in short-time activation mode, turn the device on standby. To activate the CO-
MR, press and hold the remote control button. Release the remote control button to deactivate the
CO-MR.
6. Observe the scene. Adjust the focus by rotating the CO-MR focus knob until the image becomes
clear and sharp.
7. Adjust the image contrast by rotating the CO-MR gain control knob.
8. If the day scope includes a focusing ring (i.e., parallax adjustment knob), adjust the focus for a paral-
lax free image.
9. Turn on the day scope’s reticle illumination and adjust the reticle brightness.
CAUTION:
DO NOT leave the CO-MR activated if it is not being used.
3.3.2 OPERATING THE IR850
Use the IR850 in poor light conditions or complete darkness.
CAUTION:
The light from the IR illuminator will be invisible to the naked eye. However, the light can be
detected by other NVDs.
CAUTION:
DO NOT leave the IR850 activated when the device is not in use.
1. After examining a scene with the CO-MR, turn the IR850 on.
2. To change the radiated power level, turn the power switch to one of the spots between the two OFF
positions.
3. To adjust IR beam divergence, turn the lens.
