Getting Started
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:
°
°
°
°
0
C to 40
C [32
F to 104
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.
Maintenance
The camera mechanism may cause abnormal noise due
to wear and lubrication loss after a long period of use.
To maintain optimum performance, we recommend
periodical maintenance. If abnormal noise occurs,
consult with your Sony dealer.
Note on laser beams
Laser beams may damage a CCD. You are cautioned
that the surface of a CCD should not be exposed to
laser beam radiation in an environment where a laser
beam device is used.
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.
White flecks tend to be seen particularly in the following
cases:
• during operation at a high environmental temperature
• when you have raised the gain (sensitivity)
• when the shutter speed is set to 1/30 sec., or slower, for
the BRC-300 or 1/25 sec., or slower, for the BRC-
300P
This symptom may be improved by turning the camera
off and then on again.
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.

Aliasing
When fine patterns, stripes, or lines are shot, they may
appear jagged or flicker.
