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.
