"Normal" refers to authentication model. The "Normal" authentication model is the same authentication / security that you have with the File Bound Book. You only have the ability to specify a single password that protects the bound book from being opened.
This is completely optional. If don’t specify a password EZ Arms Keeper will automatically open the last open Bound Book when the program is started. If you do specify a password when EZ Arms Keeper is automatically opening the last bound book you will need to specify this password as well as anytime you go to File->Open and choose this bound book.
That’s all there is to it. You can now use the bound book exactly like you would a File Bound Book.
