 A continuously displayed radio mast icon indicates that the DCF signal was received successfully
 We recommend a minimum distance of 2.5 meters to all sources of interference, such as televisions or computer
monitors
 Radio reception is weaker in rooms with concrete walls (e.g.: in cellars) and in offices. In such extreme
circumstances, place the system close to the window.
