Precautions
Precautions
Operating or storage location
Avoid operating or storing the system in the following
locations:
• Extremely hot or cold places
• Humid or dusty places
• Places exposed to strong vibration
• Close to sources of strong magnetism
• Close to sources of powerful electromagnetic radiation,
such as radios or TV transmitters
• Noisy places
LCD screen
Notes on use
• Do not expose the LCD screen surface to the sun. Doing
so may damage the screen surface.
• Do not push or scratch the LCD screen, or place objects
on top of the system. The image may become uneven or
the LCD panel may be damaged.
• If the system is used in a cold place, a smear may occur
in the picture or the picture may become dark. This does
not indicate a failure. These phenomena improve as the
temperature rises.
• Ghosting may occur when still pictures are displayed
continuously. It may disappear after a few moments.
• The screen and cabinet get warm when the system is in
use. This is not a malfunction.
Display pixels
Although the LCD display panel is made with high-
precision technology and has an effective picture element
ratio of over 99.99%, black dots (dead pixels) may appear
on the screen or pixels may become permanently lit (red,
blue, green, etc.) or unlit. The appearance of dead pixels
after extended periods of use is common among LCD
display panels. Be aware that such appearances do not
represent a malfunction.
Phenomena specific to CMOS sensors
The following phenomena that may appear in images are
specific to CMOS (Complementary Metal Oxide
Semiconductor) sensors. They do not indicate
malfunctions.
White flecks
Although the CMOS 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 CMOS 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)
Aliasing
When fine patterns, stripes, or lines are shot, they may
appear jagged or flicker.
Built-in speakers
The speakers generate magnetism. To avoid damaging the
data, keep magnetic tapes and disks away from the
speakers.
Cleaning
• Before cleaning, disconnect the power cord from the AC
outlet.
• The LCD screen surface is finished with a special
coating. To remove dust from the screen surface, wipe
gently with a soft, dry cloth.
• Do not use volatile solvents such as alcohol, benzene or
thinners as they may damage the surface finishes.
• When you use chemical cleaning cloth, observe the
instructions that come with it.
• Do not apply volatile solvents such as an insecticide to
the screen, or allow rubber or plastic objects to touch to
the screen for a long time, as they may damage the
surface finishes.
Note on laser beams
Laser beams may damage a CMOS sensor. You are
cautioned that the surface of a CMOS sensor should not
be exposed to laser beam radiation in an environment
where a laser beam device is used.
