The error detection setting in respect of the time is highly sensitive, which means that even very minor irregulari-
ties may result in an error message. Before calling customer service, access the Day/Time menu and set the
time. Only if this error message recurs repeatedly is the error serious enough to call customer service.
Your fitter will naturally be available to assist you in the event of faults.
