Cannot Set Date -Time on IBM Thinkpad 600

I have several 600’s and they all have the same issue. They are giving 161 192 163 errors. I replaced the battery in them and then go to try and setup the time. However, instead of letting me set the time, it gives me an – – – -> pointing to a book and I am assuming that it is telling me to look at the manual.

To back up a bit, these machines appear to have been setup with a blank power on password. Once I get the error messages and hit enter, it get the OK with the arrow and it moves on. I am “assuming” that the password isn’t causing an issue, but then again maybe I am off.

Help on this would be appreciated. Normally i get 161,163, 192, I replace the battery and move on. This has me a bit stumped.
