projector or remote control to restore the image. The word 'BLANK' appears at the lower
right corner of the screen while the image is hidden.

taken on the blank screen.
Once Blank is pressed, the projector enters Economic mode automatically.

Do not block the projection lens from projecting as this could cause the blocking object to
become heated and deformed or even cause a fire.

m–3000 m above sea level, and temperature is between 0°C–35°C.
