To reset the lamp timer:
1) With the projector plugged in and turned off, press the 'ON/STANDBY' button to put the projector in 'STANDBY' mode. NOTE: You have to press the button on the projector itself, you cannot use the remote for this step (this is not clear in manual).
2) Now, using the remote, press the following keys in order: RESET, <--, -->, ENTER.
3) Timer should now read '0'.
