	CAUTION
Do not apply solvents or similar liquids to the camera, the cables, or other items. This can cause damage.

	CAUTION
If you use a lens cleaning cloth it must be dry. Do not use a lens cleaning cloth with the liquids that are listed above. These liquids can cause material on the lens cleaning cloth to become loose. This material can have an unwanted effect on the surface of the lens.

	WARNING
Make sure that you read all applicable MSDS (Material Safety Data Sheets) and warning labels on containers before you use a liquid: the liquids can be dangerous.

	CAUTION
Be careful when you clean the infrared lens. The lens has a delicate anti-reflective coating. Do not clean the infrared lens too vigorously. This can damage the anti-reflective coating.

	CAUTION
In Step 2 below, do not use pressurized air from pneumatic air circuits in a workshop, etc., as this air usually contains oil mist to lubricate pneumatic tools.
