Test network works fine, but when I open the voting none of the keypads opens.

The Functionality of the base-station is changed. The keypads are initialized in NEW FUNCTIONALITY and now the base-station is in STANDARD Functionality or vice versa. This means test network will function, but the keypads do not open and you cannot vote with the keypads. Put the keypads back in the charging cases and turn the power on, wait 3 minutes and initialize again.
