It is possible that the OSD is set to [OFF]. Press the [ON SCREEN] button on the remote control to make the OSD visible.
Network function and RS-232C control cannot be used in standby mode. Why?

Is the lamp power setting automatically changed from [NORMAL] to [ECO]?

Is there a time limit for using the shutter function?
No, there is no time limit when using the shutter function.

The <LAMP1> / <LAMP2> lamp indicator is blinking red three times. What should I do?
This indicates that an abnormality has been detected in the lamp or the power supply circuit for the lamp. If the power is turned off and then back on immediately, the lamp light source may not cool down sufficiently, causing this symptom. Please wait for a while before turning the power back on. If the <LAMP1> / <LAMP2> lamp indicator still blinks, please contact your point of purchase, or click here to obtain the contact details of a sales office in your region.
Why is <ON (G) / STANDBY (R)> power indicator blinking green and why is no image projected?
