Is it safe to plug in the AC adaptor and change the batteries while the 71b is off?

Thanks, dmh

I just noticed that you are Calculator Clique...

Thanks for your posting on FORTH on the 75 - i watched that a couple of times...

IF you are working with FORTH on the 71B and have the Forth in a MULTIMOD card-reader module, you need to take a specific precaution for that module.

Elsewhere on this site Multimod - Memory Lost you can see that when you turn the 71B OFF, it is not really OFF for some time - and swapping batteries needs some extra care.
