Abnormal behaviour
There is a coloured dot (bright dots, dark dots, stationary dots, and/or
flickering dots) on the screen.
— This projector was produced with high precision technology. However,
a tiny dark or bright dot may appear on the screen. This is a common
occurrence due to the production process, and it does not indicate a
functional failure.
The remote control may not work properly where a lamp with electronic
stabiliser or a three-wavelength lamp is installed.
— In this case, replace the lamp with electronic stabiliser or the three-
wavelength lamp with international standard products to ensure the
remote control works properly.
