13.1 Maintenance
The 3490HD series maintenance requirements are minimal, requiring only occasional exterior cleaning as
described below:
Non-Optical Surfaces
Clean the exterior enclosure as deemed necessary (likely for aesthetic, not operational purposes). Use a soft
cloth and commercially available foaming cleaner for metal/painted surfaces.
Optical Surfaces
Clean the camera system window as needed. Use a soft non-abrasive cloth, such as terry cloth or microfiber
cloth, and a foaming glass cleaner.
Thermal Lens Surfaces
Use the following solvents for cleaning:
l
Acetone – to remove grease
l
Ethanol – to remove fingerprints and other contaminants
l
Alcohol – for final cleaning (before use)
Below are steps for cleaning the thermal lens:
1. Immerse the tissue paper in alcohol / propanol / acetone, or ethanol (reagent grade).
2. Wipe the lens in "S" motion (so that each area of the lens will not be wiped more than once).
3. Repeat stage 2 until the lens is clean. Use a new tissue each time.
