Filter cartridge
This projector provides mechanical sensor switches, the one is for filter cartridge switch (SW1891) and the other
one is for lamp cover switch (SW90). The filter cartridge switch detects whether the filter cartridge is installed cor-
rectly. If the filter cartridge is not installed correctly, the projector cannot turn on.
The lamp cover switch detects whether the lamp cover is closed securely. If lamp cover is opened or not closed com-
pletely, the drive signal to the lamp circuit is cut off. After opening the lamp cover for replacing the lamp ass’y, place
the lamp cover correctly otherwise the projector cannot turn on.

Indicators
The projector is shut down; and the LAMP indicator is lighting
and other indicators are blinking.
When the projector detects an abnormal condition (SW90, SW903, SW904
- opens, or SW1891 - opens), it will be automatically shut down to protect the
inside of the projector and the LAMP indicator lights on and other indicators
blink. In this case, unplug the AC power cord and check that the filter car-
tridge and lamp cover are installed securely, and the plug it, and turn on the
projector once again to verify operation. If the projector cannot be turned on
and these indicators are still lighting and blinking, unplug the AC power cord.
