emissions.
Four brightness modes of the lamp can be selected: [OFF], [AUTO ECO], [NORMAL] and [ECO] modes.
[ECO MODE] Description Status of LAMP indicator
[OFF] The lamp brightness is 100%. Off
[AUTO ECO] Lamp power consumption will be changed between
[OFF] and [NORMAL] automatically according to
picture level
NOTE: A bright gradation may be less visible depending
on the image.
[NORMAL] Lamp power consumption: approx.80% brightness.
The lamp life will extend by lowering the lamp power. Steady Green
light
[ECO] Lamp power consumption (approx. 60% brightness).
The lamp life will extend longer than the one on
NORMAL mode by controlling power appropriate for
the lamp. The maximum power becomes equivalent
to the power in NORMAL.
To turn on the [ECO MODE], do the following:
1. Press the ECO Button on the remote control to display [ECO MODE] screen.
2. Press the ECO button again to select a mode you wish.
• Each time the ECO button is pressed, the choices will be changed:
OFF
→
AUTO ECO
→
NORMAL
→
ECO
→
OFF
TIP:
• The leaf symbol at the bottom of the menu shows the current selection of ECO mode.
NOTE:
• The [ECO MODE] can be changed by using the menu.
Select [SETUP] → [GENERAL] → [ECO MODE].
• The lamp life remaining and lamp hours used can be checked in [USAGE TIME]. Select [INFO.] → [USAGE TIME].
• The projector is always in [NORMAL] 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.
• 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.
• Immediately after [ECO MODE] is changed from [ECO] to one of [OFF], [AUTO ECO], or [NORMAL], the lamp brightness may
decrease temporarily. This is not a malfunction.
