• The projector does not display anything on the screen or output sound when
it is turned on.
• The product emits smoke or a burning smell.
• Water or foreign substances are present inside the product.
• Part of the projected image is cut out.
• A strange noise (crackling or sparking sound) regularly occurs from inside
the projector.

In this case, stop using the product.
• For safety, turn off the power switch and remove the plug from the socket.

Abnormal behavior
• There is a colored 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
stabilizer or a three-wavelength lamp is installed.
– In this case, replace the lamp with electronic stabilizer or the three-
wavelength lamp with international standard products to ensure the
remote control works properly.
