For your safety
This equipment has been designed and manufactured to meet international safety standards, but like any
electrical equipment, care must be taken if you are to obtain the best results and safety is to be assured. So,
please read the points below for your own safety. They are of a general nature, intended to help you with all your
electronic consumer products and some points may not apply to the goods you have just purchased.
Air Circulation...

connect to a DC supply or any other power source. DO ensure that the TV is not standing on the mains lead. DO
NOT cut off the mains plug from this equipment, this incorporates a special Radio Interference Filter, the removal
of which will impair its performance. The fuse should only be replaced by a correctly rated and approved type
and the fuse cover must be refitted. IF IN DOUBT PLEASE CONSULT A COMPETENT ELECTRICIAN.
DO read the operating instructions before you attempt to use the equipment.
DO ensure that all electrical connections (including the mains plug, extension leads and inter-connections
between pieces of equipment) are properly made and in accordance with the manufacturers' instructions.
Switch off and withdraw the mains plug before making or changing connections.
DO consult your dealer if you are ever in doubt about the installation, operation or safety of your equipment.

front AV panel (See page 20), When this projection TV is installed first time or it has been moved or its direction
has been changed.
After this Auto adjustment, if the picture effect is still not satisfactory, please adjust it by using Manual

DON'T obstruct the ventilation openings of the equipment with items such as newspapers, tablecloths, curtains,
etc. Overheating will cause damage and shorten the life of the equipment.
DON'T allow electical equipment to be exposed to dripping or splashing or objects filled with liquids, such as
vases, to be placed on the equipment.
DON'T place hot objects or naked flame sources, such as lighted candles or nightlights on, or close to
