HOW TO PERFORM A NUC

NUC'ing is required to improve image quality when the image is degraded by var-
ious environmental events.
There are multiple NUC tables to span the full operating temperature range, and
the camera automatically selects the optimum table based on its temperature.
Example: Change of temperature, continues viewing of a particular warm object,
movement from one environment to another all may cause image degradation.
To clean up the image you will need to press the NUC from the Shortcut
Carousel while closing the objective lens with a solid object (lens cap,
hand, book, etc..).
PIXEL CORRECTION PROCEDURE
Pixel Correction Procedure is intended to correct "neutral" pixels that are visible in
the FOV, but are not responding to the changing environment or scenery. They may
be white or black and remain static and or nonresponsive.
1. Enter the Carousel by pressing the "Enter" key
2. Select System Settings
3. Select Thermal Category
4. Select Pixel Correction Subcategory
5. Select Manual Correction
6. You should see a targeting reticle, use the key pad to move the reticle over
the neutral pixel. If it is hard to target the neutral pixel, press the enter button and
select zoom. Use the up and down keys to zoom in and out on to the neutral pixel in
order to isolate it. Once you have isolated the neutral pixel, press the enter button to
escape from the zoom function.
7. Once the reticle is positioned over the neutral pixel, press the enter button and
select save. This should correct the pixel.
NOTE
If after you have done the procedure outlined above and the neutral pixel has
not been corrected. Try the process on a pixel directly adjacent to the neutral
pixel in order to make a uniformed correction in the FOV.
