Precautions

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

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.

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.

The speakers generate magnetism. To avoid damaging the 
data, keep magnetic tapes and disks away from the 
speakers.

• 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.
