TROUBLESHOOTING
The following conditions may be observed when using a CCD camera and are not
necessarily a fault of the camera.
Vertical smear This may occur when viewing a bright object or an intense
reflection.

when the camera is operated at a high temperature.
Jagged picture Becomes noticeable when viewing stripes, straight lines, or
similar patterns.

cameras. If a camera fails to function properly, confirm that
all necessary connections are in order and that lens
adjustments are correct for the application.
MAINTENANCE
Be careful not to spill water or other liquids on the unit.
Avoid operating or storing the unit in the following locations:
Extremely hot or cold places. The operating temperature of CCC4000 Series cameras
is 14° to 122°F (10° to 50°C).
