Why are there ratings from 2014 and 2016 here (for Helsinki 220 DAB and Stockholm 230 DAB) when the linked manual says "sales start July 2017"? At least the Stockholm 230 DAB looks completely different from the London 470 DAB and has a different feature set, so that some answers to questions here are not correct at all, such as the answer about saving the settings after power loss. According to the manual, the London 470 DAB has an EEPROM that permanently stores the settings.
