Important safety instructions 8
• 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, 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 to enable pixel shift under the
General settings.
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

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.

local regulations or waste disposal provider.
