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.
Lamp usage time: the actual usage time of each lamp mode during the operation.
Equivalent Lamp hour = Total lamp hour
= 2*(hours used in Normal mode) + 1.4*(hours used in Eco
mode) + 1*(hours used in SmartEco mode)
To obtain the lamp hour information:
1.
Press MENU and then use the arrow keys (▲/▼/◄/►) to go to Information or
Settings > Information.
2.
The Lamp Usage Time information displays.
3.
Press BACK to exit.
Extending lamp life
The projection lamp is a consumable item. To keep the lamp life as long as possible, you
can do the following settings via the Advanced OSD menu.
To access the Advanced OSD menu, see
"About the OSD Menus" on page 32
for details.
Setting Lamp Power
Setting the projector in Economic or SmartEco mode also extends the lamp life.
Using Economic mode reduces system noise and power consumption by 30%. Using
SmartEco mode reduces system noise and lamp power consumption by up to 70%. If the
Economic or SmartEco mode is selected, the light output will be reduced and result in
darker projected pictures.
