Cleaning
Turn off all power to the equipment and secure all covers before cleaning the units.
Otherwise, damage to the equipment or injury to you could occur.
Controller and Camera
Although there is no periodic maintenance that must be performed on the NTE/CDD
Detector, users are advised to wipe it down with a clean damp cloth from time to time.
This operation should only be done on the external surfaces and with all covers secured.
In dampening the cloth, use clean water only. No soap, solvents or abrasives should be
used. Not only are they not required, but they could damage the finish of the surfaces on
which they are used.
Optical Surfaces
Optical surfaces may need to be cleaned due to the accumulation of atmospheric dust.
We advise that the drag-wipe technique be used. This involves dipping a clean cellulose
lens tissue into clean anhydrous methanol, and than dragging the dampened tissue over
the optical surface to be cleaned. Do not allow any other material to touch the optical
surfaces.
