• If the projector is overheated in Normal mode, there may be a case where the Lamp mode automatically changes to Eco mode
to protect the projector. When the projector is in Eco mode, the picture brightness decreases. When the projector comes back
to normal temperature, the Lamp mode returns to Normal mode.
Thermometer symbol [ ] indicates the lamp mode is automatically set to Eco mode because the internal temperature is too
