If still not success, daily reception stops.
INFORMATION
• The flashing "radio tower" symbol stands for DCF radio signal reception has started.
- Continuous "radio tower" symbol stands for DCF radio signal reception has been successful.
- Please observe a minimal distance of 2.5m to sources of interference such as televisions or computer screens.
- The radio signal reception is weaker in rooms with concrete walls, e.g. in the basement and in office buildings. For extreme cases, please put the clock near a window.
- There are less atmospheric disturbances at night. A radio time signal reception is usually possible at that time. One synchronisation per day is sufficient to keep the time display accuracy at 1 second.
TIP
You can adjust the time manually in case the clock cannot receive the DCF time signal due to interferences, large distance to the sender, obstructions like mountains, etc. As soon as the time signal can be received, the clock will be adjusted automatically. Time signal sender coverage up to 1500km distance to Frankfurt/Main.
