What can I do if my DAB radio does not work?

  • Check at a neighbor whether it works there
  • Try to optimize the antenna and also change the location of the radio
  • Switch off recently switched on electrical devices (because possible sources of interference, such as PC, WLAN, light, power supplies, control systems, electrical devices)
  • Separate the radio from electricity (or remove batteries) and switch it on after about a minute
  • Perform a new automatic search on the radio
  • Possibly carry out a "reset" on the radio to  factory settings (attention: all previous list and settings will be  deleted) and start a new search
