Normal . . . Normal brightness.

Eco 1. . . . . Lower brightness and Fan speed decrease. Lower brightness reduces the lamp power consumption and extends the lamp life.

Eco 2. . . . . Lower brightness and Fan speed increase. Lower brightness reduces the lamp power consumption and extends the lamp life. It is recommended to use Eco 2 when using the projector continuously over a long period of time.

Lamp life control

Mode 1 . . . A lamp can be turned on even after exceeding the recommended total hours of use.

Mode 2 . . . A lamp is not turned on after exceeding the recommended total hours of use.

Lamp interval

This function can be used to automatically switch the lamp that is turned on after a certain period of time in order to reduce the lamp deterioration when 'Lamp1' or 'Lamp2' has been selected in 'Lamp mode' setting.

Use the Point  buttons to select from (Off/Auto/24H/ 200H/500H/1000H/2000H).

Note:

•“User” cannot be selected when the image is not captured.

Note:

•When switching from one of lamps to the other (e.g. when switching from Lamp1 to Lamp2), both lamps will light until the brightness of the lamps are stabilized.

•When neither of the two lamps is lighted, the projector will shutdown automatically.

•When either of the two lamps does not light up, the LAMP 1/2 REPLACE indicator blinks orange and the projector will light the other automatically. (X mark will appear on the unlighted lamp in the Lamp Status Display. See page 67 for details.)

Note:

•The fan noise becomes louder in Eco 2 than in Eco 1. Select the suitable mode for the used environment.

Note:

•If Mode 2 has been selected and either of two lamps exceeded its recommended total hours of use, Lamp interval mode will be fixed to ‘Off’. Also, ‘2-Lamps’ icon in the Lamp mode and the icon of lamp which exceeded its recommended total hours of use will be displayed in grayout.

•If Mode 2 has been selected and both lamps exceeded the recommended total hours of use, the warning icon will be displayed at the time of power-on. Then the projector will turn off after 3 minutes.

Note:

•When either of the two lamps is out, the projector will light the other automatically even if 'Off' is selected.

•When ‘AUTO’ is selected, the projector automatically detects which lamp is used less often than the other at the time of power-on and lights it.

•The setting values of time interval may not be accurate, and should be used only as a guide.
