• DCF radio signal search starts automatically about 3 minutes after battery exchange. The
“radio tower” signal is flashing.
• Press“+“ “-“ for more than 3 seconds to enter or quit the Radio controlled signal reception
• The clock synchronizes with the DCF radio signal automatically and daily from AM 1:00 to
3:00 to correct potential time deviations each hour. If the synchronization is unsuccessful
(“radio tower“ symbol disappears), a further synchronization attempt is made From 4:00 and
5:00 until success.This process is repeated up until 5:00 AM. If still not success, daily
reception stop.
Information
• Flashing “radio tower” symbol stands for DCF radio signal reception started.
• Continuous “radio tower” symbol stands for DCF radio signal reception 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 radio signal (due to
interferences, large distance to the sender, obstructions like mountains, etc.) As soon as the radio
signal can be received, the clock wil be adjusted automatically.
Radio signal sender coverage up to 1500km distance to Frankfurt/Main.
