Note
• Allow a margin of error in the value in the diagrams above.
• When the distance from the lens center to the bottom of the image [H] is a negative number, this indicates
that the bottom of the image is below the lens center.
• See page 18 about projection distance [L] and distance from the lens center to the bottom of the image [H].

projector, and the power supply recovers immediately after that, the lamp indicator will illuminate in red
and the lamp may not be lit. In this case, unplug the power cord from the AC outlet, replace the power
cord in the AC outlet and then turn the power on again.
• The cooling fan keeps the internal temperature of the projector constant and this function is controlled
automatically. The sound of the cooling fan may change during operation because the fan speed may
change and this is not a malfunction.
