Hi mate,

Did you win with your Scalable controller?

To login try: ABCD

To reset a fatal error from the controller, go to command and Clearblocking, which should reset your fault.
Before just have a look at the error log to investigate the fault, you should have a description on SMLCD
Sorry I don't have any manual, we connect our phone directly to the controller to have a look error description.

Cheers
