• The projector is always in [ON] for 90 seconds after the lamp is turned on and while the POWER indicator is blinking green. The
lamp condition will not be affected even when [ECO MODE] is changed.
• If there is no signal for about one minute, the projector will display a blue, black or logo background (depending on setting) and
go into [ON].
The projector will return to the [OFF] mode once a signal is accepted.
• If the projector becomes overheated in [OFF] mode because of use in a high-temperature room, there may be a case where the
[ECO MODE] automatically changes to [ON] mode to protect the projector. This mode is called “forced ECO mode”. When the
projector is in [ON] mode, the picture brightness decreases. The LAMP indicator’s steady light indicates the projector is in [ON]
mode. When the projector comes back to normal temperature, the [ECO MODE] returns to [OFF] mode.
Thermometer symbol [ ] indicates the [ECO MODE] is automatically set to [ON] mode because the internal temperature is too
high.
