Operating Precautions; Phenomena Specific To Ccd Image Sensors - Sony IPELA SNC-DF40N Manuel D'installation

Operating Precautions

Operating or storage location
Avoid operating or storing the camera in the
following locations:
• Extremely hot or cold places (Operating
temperature: –10°C to +50°C [14°F to
122°F])
• Exposed to direct sunlight for a long time,
or close to heating equipment (e.g., near
heaters)
• Close to sources of strong magnetism
• Close to sources of powerful
electromagnetic radiation, such as radios
or TV transmitters
• Locations subject to strong vibration or
shock
Ventilation
To prevent heat buildup, do not block air
circulation around the camera.
Transportation
When transporting the camera, repack it as
originally packed at the factory or in
materials of equal quality.
Cleaning
• Use a soft, dry cloth to clean the external
surfaces of the camera. Stubborn stains
can be removed using a soft cloth
dampened with a small quantity of
detergent solution, then wipe dry.
• Do not use volatile solvents such as
alcohol, benzene or thinners as they may
damage the surface finishes.
Phenomena Specific
to CCD Image
Sensors
The following phenomena that may appear
in images are specific to CCD (Charge
Coupled Device) image sensors. They do not
indicate malfunctions.
White flecks
Although the CCD image sensors are
produced with high-precision technologies,
fine white flecks may be generated on the
screen in rare cases, caused by cosmic rays,
etc.
This is related to the principle of CCD image
sensors and is not a malfunction.
The white flecks especially tend to be seen
in the following cases:
• when operating at a high environmental
temperature
• when you have raised the gain (sensitivity)
Vertical smear
When an extremely bright object, such as a
strong spotlight or flashlight, is being shot,
vertical tails may be produced on the screen,
or the image may be distorted.
Monitor
screen
Aliasing
When fine patterns, stripes, or lines are shot,
they may appear jagged or flicker.
Note on laser beams
Laser beams may damage the CCDs. If you
shoot a scene that includes a laser beam, be
careful not to let a laser beam become
directed into the lens of the camera.
