Hi there in Singapore = If your BC2 has been powered off for some time, you will need to re-enter the 4-digit pin code to reawaken the socket unit. Have you tried this, already? Also, you could try entering the service code ie press the double left-pointing arrows three times then enter 11111. There is lots of service info in the products section, if you are able to go there - follow the links. Good luck = Brian (Northumberland)
