A friend who is currently in hospital asked if I would try to sort out his Nanocom 1 whilst he is otherwise engaged.

He bought it from Bearmach and says that it has never been registered or upgraded since buying it. From what I can make out it has firmware version 2.03 loaded but I don't seem to be able to find a serial number.

Is it correct that to upgrade the firmware, I need to buy a new resonator and firmware installer?

Is it possible to register the unit with BBS as it was purchased from Bearmach originally? What details would be required to register the unit?

I looked at the hardware installation guide in relation to replacing the resonator and the unit I have appears to have two resonators. One is in the same exact place as the one pictured in the description and one is slightly to the right of the other.

Any advice would be appreciated.
