Can someone give me the remote keys to display the lamp hours on a Mits 73833?

I am about to install a new bulb, as the old one is becoming yellow and darker. I remember that there was a key entry sequence on the remote to display the hours on a particular bulb, but that info has long since been lost. Also, is there a way to zero the counter when installing the bulb?

Thanks for any help.

Can anyone with a similar (73") Mits give me the keys to get the lamp life?

Thank you very much. I would like to keep track of how long this bulb lasts.
