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.
