Precautions with regard to safety
Cautions on use
In order to get the picture quality
Draw curtains or blinds over windows and turn off any lights near the screen to prevent outside light or light from indoor lamps from shining onto the screen. Depending on where the projector is used, air exhaust vents or the warm air from air conditioning can cause a shimmering effect on the screen. For this reason, take care not to shield the air exhaust vents and con- sider the direction of the air flowing from air condition- ing.
Do not touch the surface of the projector lens cover with your bare hand.
If the surface of the lens becomes dirty from finger- prints or anything else, this will be magnified and projected onto the screen.

Important Information
Do not move the projector while it is operating or subject it to vibra- tion or impact.
The service life of its internal components will be shortened.
The projector has a high pressure mercury lamp that is characterised as follows:
zzThe brightness of the lamp will decrease over time. zzThe lamp may explode or shorten the lamp life by
shocks or chipping damage.
zzIn rare cases, it may burst shortly after the first use.
zzThe possibility of its bursting increases when the lamp is used beyond the replacement time.
zzIf the lamp bursts, gas inside the lamp is released in the form of smoke.
zzThe life of a mercury lamp varies according to the individual difference or conditions of use.
zzIn particular, turning the power on and off frequently and/or repeatedly as well as continuous use for
10 hours will greatly affect the life cycle. Provide a lamp for replacement in advance.
Connection to external device
When connecting the projector to a computer or external device, use the mains lead supplied with the corresponding device and a commercially available shielded interface cable.
Optical components
It may be necessary to replace the optical compo- nents such as Liquid crystal panels and Polarizing plates in less than 1 year if using the projector in a high temperature environment or in a very dusty, oily smoke or tobacco smoke environment. For more details, please contact your dealer.
Security instruction
zzThe connecting network must be secured by fire- wall or others.
zzChange your password regularly.
zzDo not use a password that is simple to guess.

Cleaning and maintenance
Ask an Authorised Service Centre to clean the inside of the projec- tor at least once a year.
If dust is left to build up inside the projector without being cleaned out, it can result in fire or problems with operation. It is a good idea to clean the inside of the projector before the season when humid weather ar- rives.
Ask your nearest Authorised Service Centre to clean the projector when required.
Please discuss with the Authorised Service Centre regarding cleaning costs.
