Question about Braun Series 7

Use the cleaning station from my old shaver series 7 760 cc

There is no cleaning station for this, no. :-( This is generally the case with all models that have the letter 's' in the model number. This stands for 'Solo' and these models do not have a chip for communication with the station. This function is the exclusive responsibility of the "cc" models, which are also sold with a cleaning station.
