satisfactorily does not imply that the
power outlet is grounded or that the
installation is completely safe. For your
safety, if you are in any doubt about the
effective grounding of the power outlet,
please consult a qualified electrician.
The lightning flash with arrowhead
symbol, within an equilateral triangle, is
intended to alert the user to the presence
of uninsulated "dangerous voltage" within
the product's enclosure that may be of
sufficient magnitude to constitute a risk of
electric shock to persons.
The exclamation point within an
equilateral triangle is intended to alert the

Notes on the LCD panel of this display
• The Liquid Crystal Display (LCD) panel of this display has a very thin protective layer of
glass which is liable to marking or scratching, and cracking if struck or pressured. The
liquid crystal substrate is also liable to damage under excessive force or extreme
temperatures. Please handle with care.
• The response time and brightness of the LCD panel may vary with the ambient
temperature.
• Avoid placing the display in direct sun or where direct sun or spot lighting will shine onto
the LCD panel, as the heat may damage the panel and the external casing of the display,
and the bright light will make viewing the display more difficult than necessary.
• The LCD panel consist s of individual pixels to display images and is manufactured
according to the design specifications. While 99.9% of these pixels work normally, 0.01%
of the pixels may remain constantly lit (in red, blue or green) or unlit. This is a technical
limitation of the LCD technology and is not a defect.
• LCD screens, like plasma (PDP) and conventional CRT (Cathode Ray Tube) screens, are
also susceptible to 'screen burn-in' or 'image retention' which can be found on the screen
as visible fixed lines and shades. To avoid such damage to the screen, avo id displaying
still images (like On-Screen Display menus, TV station logos, fixed/inact ive text or icons)
for more than two hours. Change the aspect ratio from time to time. Fill the entire screen
with the image and eliminate the black bars whenever possible. Avoid displaying images in
4:3 aspect ratio over a long period of time, otherwise there may be visible burn marks on
the screen as two vertical lines.
If display of a still image is required, it is recommended to enable Image Retention under
the Setting > Advanced menu.
Note:
• Under certain circumstances, condensation may occur on the inner side of t he cover glass, it's a
natural phenomenon and will not affect the operation of the display. This condensatio n wil l usu ally
disappear after around 2 hours of normal operation.
