Reception of the Radio signal

fresh batteries. The radio mast icon starts to flash.
 At 1:00 /2:00 / 3:00 am, the clock automatically carries out the synchronization procedure
with the DCF signal to correct any deviations to the exact time. If this synchronization

automatically attempt another synchronization at the next full hour. This procedure is
repeated automatically up to total 5 times.

radio mast icon disappears) and start again at the next full one hour.
