❹ Changing Eco Mode/Checking Energy-Saving Effect

Using Eco Mode [ECO MODE]

The ECO MODE (NORMAL and ECO) increases lamp life, while lowering power consumption and cutting down on
CO emissions.
2
Four brightness modes of the lamp can be selected: [OFF], [AUTO ECO], [NORMAL] and [ECO] modes.
[ECO MODE]
[OFF]
[AUTO ECO]
[NORMAL]
[ECO]
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 and DYNAMIC CONTRAST features control the lamp power. Some pictures may become extremely bright when
using both ECO MODE and DYNAMIC CONTRAST features to control the lamp power. To avoid this phenomena, turn off the ECO
MODE and DYNAMIC CONTRAST.
• Immediately after the menu item is selected for [ECO MODE], the screen may flicker. This is not malfunction.
• Using the projector in the [AUTO ECO], [NORMAL], or [ECO] mode for [ECO MODE] may cause poor halftones depending on the
projected image.
• When [ECO] has been set for [ECO MODE], the fan noise may change in a certain cycle.
• 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].
• 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 [OFF] mode.
Thermometer symbol [ ] indicates the [ECO MODE] is automatically set to [NORMAL] mode because the internal temperature
is too high.
