What to do when these messages are displayed
Messages are displayed when the lamp life has expired and when there is input of signals that cannot be used.
Lamp Time Over: Displayed when the lamp time has exceeded 2000 hours. The message is displayed for a period of 3 minutes during each projection. Replace w1th a new lamp unit. For details on replacement of the lamp unit, please consult your authorized dealer.
Out of Range: When there is input of video signals that cannot be used with this unit. Input video signals that can be used.
No Input: When no device is connected to the input terminal. When the input terminal is connected but there is no signal. Input the video signals.
Warnings Using Indicators
The lamp time and warning mode are indicated using the indicator. For indicator displays during normal operation, refer to the note below.
