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:
Total Lamp Hour = (hours used in Normal mode) + 2/3*(hours used in Economic mode)
See "Setting Lamp Mode as Economic" below for more information on Economic mode.
To obtain the lamp hour information:
1. Press MENU and then press / until the SYSTEM SETUP: Advanced menu is highlighted.
2. Press to highlight Lamp Settings and press OK/IMAGE. The Lamp Settings page is displayed.
3. You will see the Lamp Time information appearing on the menu.
4. To leave the menu, press MENU.
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 4000 (used in Normal mode)–6000
(used in Economic mode) hours with proper usage. Such interval differs depending on the operating
environment and may be shorter than 4000–6000 hours.
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 approximately 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 / .
• When this mode is switched, the projected images may flicker.
• If this mode is frequently switched, the lamp may be deteriorated.
Setting Auto Power Off
This function allows the projector to turn off automatically if no input source is detected and no operation
is made by user 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.
