Maintenance
IMPORTANT WARRANTY INFORMATION
There are no user-serviceable parts inside the camera. Removing the rear cover of the camera
without express authorization from DVC Company will void the camera warranty.
DVC professional cameras are manufactured in a clean environment. Before shipping, each camera is
tested to assure that it meets stringent specifications for cleanliness and quality.
7.1.
Cleaning Guidelines
Frequent lens changes, especially without careful attention to contaminants, can allow debris to
accumulate on the infra-red blocking filter and lens surfaces. Therefore, DVC Company
provides the following guidelines for cleaning those components.
To minimize the need to clean the optical surfaces, do not remove the protective lens mount cap
shipped with the DVC-4000 camera until you are ready to mount the camera to the optical
system.
7.1.1.
Cleaning the lens or optical assembly
Please follow the lens manufacturer’s recommendations for cleaning. DVC Company is
not responsible for any damage caused to a lens or optical assembly caused by customer
cleaning or misuse.
To ensure optimum image quality with any DVC camera, do not remove the protective
lens-mount cap until ready to mount the camera on the application. If the camera is
removed from the application, immediately replace the cap. Doing so will keep dust and
other contaminants from accumulating on the optical surfaces. In addition, please note
the following model-specific guidelines.
7.1.2.
Standard (non-cooled) camera precautions
While the lens mounting ring and locking flange allow the user some lens back-focus
adjustment, complete removal of the ring will expose the CCD faceplate and will likely
cause debris to accumulate on its surface.
Extreme care should be taken to avoid
completely removing the lens mounting ring and exposing the CCD faceplate unless
absolutely necessary. Fingerprints or other evidence of contact with the CCD
faceplate may void the warranty.
7.1.3.
TE-Cooled camera precautions
The DVC Thermoelectrically-cooled cameras contain the CCD in a sealed, gas-filled
chamber having an anti-reflective glass window.
Do not, under any circumstances,
loosen or remove the inner glass window from a cooled camera
. Doing so will void
the warranty. If it is suspected that the seal has been broken or if the window breaks, call
DVC Customer Service. Do not apply power to the camera. Moisture will have been
introduced into the chamber, and cooling in the presence of moisture will cause
condensation and frost on the CCD, which can damage the entire cooling unit.
