Lamp use time reset
Be sure to reset the Lamp use time after replacing the lamp unit. Unless reset, the projector will cease operation (lamp will not light) when 2000 hours are reached.
Conversely, reset the use time only after replacing the lamp.
RESETTING

(2) In sequence, press the [EXIT], [ENTER] and [HIDE] buttons.
(3) Press the DOWN  button for more than 2 seconds.
The STAND-BY and LAMP LEDs alternately flash for about 3 seconds, then only the STAND-BY LED lights steadily.
RESET AFTER REPLACING PROCESSOR PWB ASS'Y
The lamp use time data are stored in memory on the PROCESSOR PWB ASS'Y and need to be reentered after replacing the PROCESSOR PWB ASS'Y. Use the special software and a personal computer to reenter the data. Afterwards, confirm the mode has been returned to that prior to board replacement.
