Lamp information
Getting to know the lamp hour
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:
• MP575/MP576
Total (equivalent) lamp hour
= 1 (hours used in Economic mode) + 4/3 (hours used in normal mode)
• MP515/MP525/MP526
Total (equivalent) lamp hour
= 1 (hours used in Economic mode) + 3/2 (hours used in normal mode)
See "Setting Lamp Mode as Economic" below for more information on Economic mode.
To obtain the lamp hour information:
1. Press Menu/Exit and then press / to highlight the SYSTEM SETUP: Advanced
menu.
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.
Extending lamp life
The projection lamp is a consumable item that normally can last up to 3000-4000 (for
the MP575/MP576) or 2000-3000 (for the MP515/MP525/MP526) hours with proper
usage. To keep the lamp life as long as possible, you can do the following settings via the
OSD menu.
Setting Lamp Mode as Economic
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 / .
Setting Auto Power Off
This function allows the projector to turn off automatically if no input signal 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.
