Troubleshooting

Due to external interference (caused by static charges from carpets, thunderstorms, etc.), the control electronics of your radio could receive bad information. If the display is incomplete or the radio is not responding to control buttons, proceed as follows:-

Remove the power supply (the mains and all batteries) and re-install them again after one minute.

This resets the radio to its initial state. The stored data for the individual memory positions, the clock, the alarm settings and the Last Station Memory are all cleared.
