About the time signal transmitter DCF77
‚ Depending on your location, it may occur in rare individual cases that the radio-
controlled clock receives signals from another time signal transmitter or even
alternately from two time signal transmitters. This is not a fault in the device. In this
case, change the location for the radio-controlled clock.
‚ The weather, e.g. a heavy storm, can cause interference with the reception.
‚ Temporary shutoffs of the transmitter can sometimes happen, e.g. because of
maintenance work.
Setting up/hanging the radio-controlled clock
The radio-controlled clock has a hanging loop and a fold-out stand on the back.
− Hang or place the radio-controlled clock as near as possible to a window. Here, the
reception will generally be best.
About the time signal transmitter DCF77
This radio-controlled clock receives its radio signals from the time signal transmitter
DCF77. This broadcasts the precise and official time of the Federal Republic of Germany
on the long-wave frequency of 77.5 kHz.
The transmitter is located in Mainflingen near Frankfurt am Main and, with its range of
up to 2000 km, supplies the majority of radio-controlled clocks in western Europe with
the necessary radio signals.
As soon as the radio-controlled clock is supplied with power, it switches to receiving
mode and searches for the signal from the transmitter DCF77. If the time signal is
received in sufficient strength, the display shows the date, time and day of the week.
The radio-controlled clock switches on several times a day and synchronises the time
with the radio signal from the transmitter DCF77. In the event the signal is not received,
e.g. during a strong storm, the device continues to run precisely and then switches to
receiving mode again at the next scheduled time.
