7.1.7.
Cleaning the CCD faceplate
The CCD faceplate is a coated optical surface and should not be exposed unless
absolutely necessary. It will be exposed if the infra-red filter is removed.
Never
attempt to clean the CCD faceplate unless the dirt or debris is a noticeable
problem in the image and cleaning the lens does not remedy the problem. Any time the
CCD sensor is exposed, it is at risk of being damaged. Use common sense, and carefully
follow these guidelines.
7.1.7.1.
What must I do before cleaning the CCD imager faceplate?
First, carefully examine the CCD faceplate in a clean location under a strong,
direct light. Try to determine if the contaminants are a few dust particles, an
oily smudge (such as a fingerprint) or both.
7.1.7.2.
What if the contamination is only a few dust particles?
If you are sure that the contamination is particulates:
•
Use a CLEAN, DRY (preferably brand-new), camel-hair lens cleaning brush
(such as those used by photographers) to gently wipe the contaminants off of the
CCD Faceplate.
•
If in doubt, or if the CCD faceplate surface is very dusty, please call DVC
customer service before proceeding.
•
7.1.7.3.
What if the contamination includes a smudge?
DVC strongly recommends returning the camera to the factory for
professional cleaning to avoid damaging the CCD faceplate.
Scratches,
chemical contamination, or other damage due to improper cleaning may
void the camera warranty.
•
Remove the camera from the optical assembly and bring the camera to a clean,
dry location where it is safe to use flammable solvents (please see caution
below).
