When the projector is in operation, the duration (in hours) of lamp usage is automatically 
calculated by the built-in timer. The method of calculating the equivalent lamp hour is as 
follows:

Total (equivalent) lamp hour
= 1 (hours used in Economic mode) + 
   4/2.5 for the MP626 | 4/3 for the MP670 (hours used in normal mode)

To obtain the lamp hour information:

1.

Press Menu/Exit and then press  /

 until the SYSTEM SETUP: Advanced menu 

is highlighted.

2.

Press 

 to highlight Lamp Settings and press MODE/ENTER. The Lamp Settings 

page displays.

3.

You will see the Equivalent lamp hour information displaying on the menu.

4.

To leave the menu, press Menu/Exit.

You can also get the lamp hour information on the INFORMATION menu.

The projection lamp is a consumable item that normally can last up to 3500-4000 hours with 
proper usage. To keep the lamp life as long as possible, you can do the following settings 
via the OSD menu.

Using Economic mode reduces system noise and power consumption by 20%. If the 
Economic mode is selected, the light output will be reduced and result in darker projected 
pictures.

Setting the projector in Economic mode also extends the lamp operation life. To set 
Economic mode, go into the SYSTEM SETUP: Advanced > Lamp Settings > Lamp 
mode menu and press 

/

.

This function allows the projector to turn off automatically if no input source is detected 
after a set period of time to prevent unnecessary waste of lamp life.

To set Auto Power Off, go into the SYSTEM SETUP: Basic > Auto Power Off menu and 
press 

/

. The time period can be set from 5 to 30 minutes in 5-minute increments. If the 

preset time lengths are not suitable for your presentation, select Disable. The projector will 
not automatically shut down in a certain time period.
