Minimize moving the CAM to and from areas of large temperature differentials
(as from a cool enclosure to direct sunlight).
c. Operation in Darkness.
The display contains light emitting diodes that light the display in
darkness. The diodes are activated anytime that the CAM is operating.
d. Operation in Blowing Sand or Dust.
Check filtered nozzle standoff for collection of dust. If dust is visible,
remove and replace the filter with a new filtered nozzle standoff.
