Lamp Management - Sanyo PLC-HF15000L Owner's Manual

Lamp Management

This Projector is equipped with 4 Projection Lamps to
ensure brighter image and those lamps are controlled by
the Lamp Management Function. The Lamp Management
Function detects the status of lamps and shows the
status on screen or on the LAMP REPLACE indicators.
This function also automatically controls the Lamp
Mode when any of lamps is out for the end of life or
malfunctions.

Lamp Status Display
The lamp status icons as shown right appears on
screen when the projector is turned on or the input
source (input 1, input 2, Input 3 or input 4) is switched.
You can also check lamp status by using the
Information window. To display the Information
window, see pages 27 and 30.
Lamp Mode Changeover
The Lamp mode function automatically changes the
lighting lamp (Lamp Mode) by detecting the status of
lamp. For example, in 4-lamps mode, if one of the 4
lamps failed, the projector operates with the rest of the
lamps, and the lamp mode automatically switches to the
3-lamps mode. To change the lamp mode manually, use
the Lamp mode function. The illustrations shown right
are the examples of on-screen lamp status in each lamp
mode. Refer to the SETTING section on pages 55, 56.
