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.

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.
