How to Clean
Clean the case with a damp cloth and a weak soap solution. Do not use
abrasives, isopropyl alcohol, or solvents to clean the case or lens/window. If
used and stored properly, the infrared lens on your Product should require only
occasional cleaning.
When necessary, to clean the lens:
1. Use a hand-squeeze air pump to gently blow off any dust or debris from
the lens surface.
2. If the lens surface requires additional cleaning, use a clean, fine-fiber or
micro-fiber cloth, dampened with a mild, soapy water solution. Gently wipe
surface of lens to remove smudges and debris.
3. Dry with an absorbent, clean fine-fiber or micro-fiber cloth.
Note
Minor smudges and dirt should not significantly affect the performance
of the Product. However, large scratches or the removal of the
protective coating on the infrared lens can affect both image quality
and the temperature measurement accuracy.
