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.

televisions or computer screens.

The radio signal is weaker in rooms with concrete walls (e.g. in the basement) and in
office buildings. For extreme cases, please put the main unit 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 will be adjusted automatically.
Radio signal sender coverage up to 1500km distance to Frankfurt/Main.
