[AUTO ECO] Light power consumption will be changed
between [100%] and [80%] automatically
according to picture level
NOTE: A bright gradation may be less visible depending on
the image.
[NORMAL] Light power consumption: approx. 80% brightne-
ss.The light life will extend by lowering the light
power.

• The projector is always in [NORMAL] for 1 0 seconds after the l ight is turned on. The l ight condition will not be affected even when
[ECO MODE] is changed.
• After a lapse of 1 minute from when the projector displays no-signal guidance, a blue, black or logo screen, [ECO MODE] will automatically
switch to [ECO]. The projector will return to its original setting once a signal is accepted.
• If the projector is overheated in [OFF] mode, there may be a case where the [ECO MODE] automatically changes to [NORMAL] mode to
protect the projector. When the projector is in [NORMAL] mode, the picture brightness decreases. When the projector comes back to normal
temperature, the [ECO MODE] returns to its original setting.
Thermometer symbol [ ] indicates the [ECO MODE] is automatically set to [NORMAL] mode because the internal temperature is too high.
