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 user to the presence of important
operating and maintenance (servicing)
instructions in the literature
accompanying the appliance.
• The mains plug of the power supply cord shall remain readily operable. The AC

• Do not place this display near water, like a spa or pool, or in a position which will allow
the splashing or spraying of water onto the display, like in front of an open window
where rain water may enter.
• Do not install this display in a confined space without proper ventilation and air
circulation, such as in a closed cabinet. Allow proper space around the display for
dissipating heat inside. Do not block any openings and vents on the display. Overheating
may result in hazards and electric shock.
• Installation of this display should only be performed by a qualified technician. Failure to
install this display properly may cause injuries and damages to the personnels and the
display itself. Check the installation regularly and maintain the display periodically to
ensure the best working condition.
• Use only the accessories approved or recommended by the manufacturer to mount this

• To reduce the risk of electric shock, do not remove covers. No user serviceable parts
inside. Refer servicing to qualified service personnel.
• To prevent personal injuries, mounting the display or installing desktop stands is
required before use.
household wiring. Extension cords
used with the equipment must have
three cores and be correctly wired to
provide connection to the ground.
Wrongly wired extension cords are a
major cause of fatalities.
The fact that the equipment operates
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.

instructions.
8. Do not install near any heat sources such as radiators, heat registers, stoves, or
other apparatus (including amplifiers) that produce heat.
9. Do not defeat the safety purpose of the polarized or grounding-type plug. A
polarized plug has two blades with one wider than the other. A grounding-type plug
has two blades and a third grounding prong. The wide blade or the third prong are
provided for your safety. If the provided plug does not fit into your outlet, consult an
electrician for replacement of the obsolete outlet.
10. Protect the power cord from being walked on or pinched particularly at plugs,
convenience receptacles, and the point where they exit from the apparatus.
11. Only use attachments/accessories specified by the manufacturer.
12. Use only with the cart, stand, tripod, bracket, or table specified by the
manufacturer, or sold with the apparatus. When a cart is used, use
caution when moving the cart/apparatus combination to avoid injury
from tip-over.

periods of time.
14. Refer all servicing to qualified service personnel. Servicing is required when the
apparatus has been damaged in any way, such as power-supply cord or plug is
damaged, liquid has been spilled or objects have fallen into the apparatus, the
apparatus has been exposed to rain or moisture, does not operate normally, or has
been dropped.
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 consists 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
Important safety instructions 3
screen as visible fixed lines and shades. To avoid such damage to the screen, avoid
displaying still images (like On-Screen Display menus, TV station logos, fixed/inactive
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.
Note: Under certain circumstances, condensation may occur on the inner side of the
cover glass, it's a natural phenomenon and will not affect the operation of the display.
This condensation will usually disappear after around 30 minutes of normal operation.
• If display of a still image is required, it is recommended that the “Anti-Image Retention”
function is enabled under the Initial Setting menu.
Safety notice for remote control
• Do not put the remote control in the direct heat, humidity, and avoid fire.
• Do not drop the remote control.
• Do not expose the remote control to water or moisture. Failure to do so could result
in malfunction.
• Confirm there is no object between the remote control and the remote sensor of the
product.
• When the remote control will not be used for an extended period, remove the
batteries.
