How do you reprogram the olympia infoglobe clock? I lost the manual. Model OL3000.2

I have the manual and can tell you what it says:
(this worked for me last year when we went off daylight savings, but for some reason, It doesnt seem to work anymore. I can't imagine that I did anything different then. You can try, though.)
Enter (or leave) the Demonstration Mode by pressing the right key for at least 1 second.
Then, by pressing SELECT key, you are SUPPOSED to be able to scan a menu which lets you pick date format, time format, etc.

This no longer works for me, and the instructions also have a contradictory comment that says the SELECT key is disabled in this mode. But perhaps this will work for you.

I would also appreciate instructions if anyone knows what I am doing wrong.
