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 (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.
The lamp hour in Economic mode is calculated as 2/3 of that in normal mode. That is,
using the projector in Economic mode helps to extend the lamp hour by 1/2.
Extending lamp life
The projection lamp is a consumable item that normally can last up to 2000-3000 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 / .
When the DCR function is set to On, the lamp mode cannot be adjusted.
• Setting Auto Power Off
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.
