9 Safety Instructions and Handling Precautions
When Using the Main Unit
• The screen may be damaged if it is left facing strong source of light. Please take precautions when placing it near
a window.
• Do not press firmly on the screen, scratch it or place an object on the screen. It can cause non-uniformity or
damage to the panel.
• The screen and cabinet may become warm during use. Note this does not constitute a malfunction.
• Depending on the environment where the video display is used, the internal temperature of the display may rise,
resulting in becoming hot to touch. Please take care when handling the video display.
• Viewing the display for prolonged periods of time may lead to eye strain or decreased vision. Please ensure to take
rest periodically to avoid these symptoms.
• Refer to Recommendation ITU-R BT.1702 "Guidance for the reduction of photosensitive epileptic seizures caused
by television" and related guidelines.
About Backlight
The backlight has a limited service life so its brightness may degrade and color may change due to aging.
About Temporary Screen burn-in
If a stationary image is displayed for a prolonged period, screen burn-in may occur where you see remnants of what
was displayed. This is a characteristic of LCD and is not a failure. However, this is only temporary and will disappear
when playing video.
About the LCD screen
The screen is produced using extremely high-precision manufacturing techniques, with more than 99.99% of the pixels
operating to specification. Less than 0.01% of the pixels may occasionally misfire or appear as black, red, blue or
green dots. In addition, this tendency may increase through long term use due to characteristic of the LCD panel.
These do not constitute a malfunction.
Condensation
If this equipment is brought into a warm room while it is cold or if the room is heated suddenly, condensation may form
on the surface or inside the equipment. Note that the equipment may be damaged if it is used under such condition.
If condensation has formed on the surface or inside the equipment, do not use the video display as it may get
damaged. Turn the power off and wait until the condensation has evaporated before using the video display.
