‚ Maintain a distance from TV sets, computers and monitors.
Base stations of cordless telephones should also not be in the
immediate vicinity of the radio-controlled alarm clock.
‚ Depending on your location, it may occur in rare individual
cases that the alarm clock receives signals from another time
signal transmitter or even alternately from two time signal
transmitters. This is not a fault in the device. In this case,
change the location of the alarm clock.
‚ The weather, e.g. a heavy storm, can cause interference with
the reception.
‚ Temporary shutoffs of the transmitter can sometimes
happen, e.g. because of maintenance work.
