The type 2 BB60C was a minor component change with no affect to the operation of the unit. You can determine if you have a BB60C-2 by connecting your unit to the PC and looking in the device manager under USB devices. It will show up as a “BB60C” for type 1 devices, and “BB60C-2” for type 2 devices.
If you are still unsure, you can contact our service department at service@signalhound.com with your serial number and we can look up your unit.
