							Safety warnings and precautions 5
Safety warnings and precautions
• The mains plug of the power supply cord shall remain readily operable. The AC 
receptacle (mains socket outlet) shall be installed near the equipment and shall be easily 
accessible. To completely disconnect this equipment from the AC mains, disconnect the 
power cord plug from the AC receptacle.
• Do not place this display on an uneven, sloping or unstable surface (such as a trolley) 
where it may fall and cause damage to itself or others.
• 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 
display. Using wrong or unsuitable accessories may cause the display to fall and result in 
serious personal injuries. Make sure that the surface and fixing points are strong enough 
to sustain the weight of the display.
• 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.THIS EQUIPMENT MUST BE 
GROUNDED
To ensure safe operation, the three-pin 
plug must be inserted only into a 
standard three-pin power outlet which 
is effectively grounded through normal 
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. 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 products 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. 
						

							Important safety instructions 6
Important safety instructions
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near water.
6. Clean only with dry cloth.
7. Do not block any ventilation openings. Install in accordance with the manufacturers 
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.
13. Unplug this apparatus during lightning storms or when unused for long 
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 7
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, its a natural phenomenon and will not affect the operation of the display. 
This condensation will usually disappear after around 2 hours of normal operation.
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.
Battery safety notice
The use of the wrong type of batteries may cause chemical leaks or explosion. Please 
note the following:
• Always ensure that the batteries are inserted with the positive and negative terminals in 
the correct direction as shown in the battery compartment.
• Different types of batteries have different characteristics. Do not mix different types.
• Do not mix old and new batteries. Mixing old and new batteries will shorten battery life 
or cause chemical leaks from the old batteries.
• When batteries fail to function, replace them immediately.
• Chemicals which leak from batteries may cause skin irritation. If any chemical matter 
seeps out of the batteries, wipe it up immediately using a dry cloth, and replace the 
batteries as soon as possible.
• Due to varying storage conditions, the battery life for the batteries included with your 
product may be shortened. Replace them within 3 months or as soon as you can after 
initial use.
• There may be local restrictions on the disposal or recycling of batteries. Consult your 
local regulations or waste disposal provider.
