Precautions

Operating or storage location
Operating or storing the camera in the
following locations may cause damage to
the camera:
• Extremely hot or cold places (Operating
°
temperature: –5 C to +45
°
113 F])
• Exposed in 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 equal in quality.
Cleaning
• Use a blower to remove dust from the lens
or optical filter.
• 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.

Precautions / Typical CCD Phenomena
Typical CCD
Phenomena
The following phenomena may appear on
the monitor screen while you are using the
DXC-C33/C33P color video camera. These
phenomena stem from the high sensitivity of
° °
C [23 F to the CCD image sensors, and do not indicate
a fault within the camera.
Vertical smear
A "smear" may appear to extend vertically
from very bright subjects, as shown below.
This phenomenon is common to CCD
imaging elements using an interline transfer
system, and is caused when electric charge
induced by infrared radiation deep within
the photo sensor is transferred to the
resistors.
Aliasing
When shooting fine stripes, straight lines or
similar patterns, the lines may become
slightly jagged.
Blemishes
A CCD image sensor consists of an array of
individual picture elements (pixels). A
malfunctioning sensor element will show up
as a single pixel blemish in the image. This
is generally not a problem.
White speckles
When you shoot a poorly illuminated object
at a high temperature, small white dots may
appear all over the entire screen image.
