Hi, meanwhile I figured out (info from local b&o-dealer) that new mainboards/devices come with serial 00000000, the correct serial has to be set with a configuration tool by the dealer/technican who changed the board.
He said that this can only be done once. So there are 3 options now:
– our devices got a new board and are not yet configured
– our devices got a new board and the person who changed it made an error in configuring, so it it not possible to enter the correct serial from now on
– our devices have a defective chip where the serial is stored (as all other settings are kept in memory after losing power maybe there is a special chip for the s/n)
I will go the dealer in the next 3 weeks and give it a try to enter the correct serial.
