Maintenance
Do not touch the CCD sensor by hand or with other objects. The sensor
can be damaged by electrostatic discharge (ESD), body oils, and particulate
matter.
Use a lens mount cover whenever a lens is not mounted on the camera to
protect the sensor from dust and dirt.
Avoid drastic temperature changes to prevent dew condensation.
When necessary, use the following procedure to clean the sensor at a
workstation equipped with anti-ESD facilities. If dust sticks to the CCD,
first attempt to blow it off from the side of the sensor using ionized air.
If oils are present on the sensor, clean the sensor with a cotton bud and ethyl
alcohol. Be careful not to scratch the glass. Use only one pass over the glass
per cotton bud to minimize the risk of recontamination and scratching.
