KRC2 battery changeover issue

KRC2 ed05
KSS 5.5.12

I’ve just changed the two backup batteries, which I installed after powering off to the controller. In hind site powering off the controller was perhaps not the correct procedure for changover.

I was expecting to have to remaster but i’m assuming as these error messages below were not there before that the error code repeating to E1 issues is directly correspondent to the battery changeover.

Error code 223,250, 1115, 206

Looks like I may have to restore some lost MADA enries related to the E1.

My question to the group is where should I look first to resolve this group of errors?

Many thanks

What about the text for each code? Nobody should expect that someone else looks for the error text when he himself is too lazy to write them down.

Ok point taken. I did wonder about that.

These are two screengrabs I took on first and second start up after installing the batteries. Perhaps there is an error log which I an attach tomorrow if that is preferable.
