Please tell me how to reset lamp timer on Hitachi...

After switching on, on the main unit press reset button and left button at same time. After a few seconds text at the very bottom of the display will show something like LAMP (1751). then release and select the same two buttons again, and then again (I think) and the LAMP (0) should appear and it is reset. if this sounds a little vague its because this is what I remember doing as I was trying different things out on my cp-x960.
