      is the "We" for eductation?

      maybe re-flash the firmware with "W" version if it exists?

        ah yes.
        The EMP-400W is basically the same device as the 400We —sans the security features.
        also found this:
        The factory default password is to hold down the number button and press 1793 on the remote control

            one of the buttons on the remote may act as a shift key.
            obviously it cant be 0-9, so there are only 5 others to try
            i wonder if the original control pcb / switches are still under the orange panel?!

                  We had these in the school where I worked. We used the remote control to unlock them.

                        for sure . I will take the risk to short them and see what will happen, even if i am not sure that i will remove easily the password this way

                          i think it will always have a password, but if you reset it then atleast you know what it is.

                              read the thread from the begining, there are reset pins inside.
