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 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.

Important safety instructions 5

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 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. 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 the cover glass, it's 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.
