CLEANING THE SCREEN

•
When the screen surface becomes dirty with dust, etc., clean it by using a soft cloth such as gauze. When
water, and volatile chemicals such as benzene, thinner, etc., spill on the screen surface, it may be subject
to damage, therefore, do not use them. Also, since the surfaces are susceptible to damage, refrain from
rubbing them with a hard material or using a duster.
Since the Projector has been adjusted at the time of shipment, avoid
making further adjustments without good reason.
The Projector is subject to colour deviation due to Convergence deviation
caused by the geomagnetism at the installation location and peripheral
magnetic field. After the installation of machine, and before commencing
operation, check for Convergence deviation and if deviated, make
adjustments.
Since the Projector screen is susceptible to damage, pay careful attention
to its handling. When cleaning, refrain from using water or volatile
chemicals.
