Replace Lamp The lamp indicated by flashing indicator, lamp 1 or 2, is due for replacement. Replace it with a new lamp. 
If you continue to use the lamp after the replacement period has passed, the possibility that the lamp may 
explode increases. Replace it with a new lamp as soon as possible.
We recommend replacing both lamps together to maintain consistent hue and brightness of projected 
images.

Images are fuzzy or out of focus
Interference or distortion appear in imagesAre the image signals being output to the projector?
Only when projecting images from a laptop computer 
or a computer with a built-in LCD screenIf the image signals are only being output to the computer's LCD monitor or to the accessory monitor, 
you need to change the output to an external destination as well as the computer's own monitor. For 
some computer models, when the image signals are output externally, they no longer appear on the 
LCD monitor or accessory monitor. For more information, see your computer's documentation.
If the connection is made while the power of the projector or computer is already turned on, the 
function [Fn] key that changes the computer's image signal to external output may not work. Turn the 
power for the computer and the projector off and then back on again.

Is the focus adjusted correctly? Press the [Focus] button on the remote control to adjust the focus. 
Is the projector at the correct distance? Is it projecting outside of the recommended projection distance range?
Setup within the recommended range. 
Is the Keystone adjustment value too large? Lower the projection angle to reduce the amount of keystone correction. 
Has condensation formed on the lens? If the projector is suddenly taken from a cold environment to a warm environment, or if sudden ambient 
temperature changes occur, condensation may form on the surface of the lens, and this may cause the 
images to appear fuzzy. Set the projector up in the room about one hour before it is used. If 
condensation forms on the lens, turn the projector off and wait for the condensation to disappear.
