Working principle

The WS8426 contains a receiver which receives a radio-signal from a radio
station located near Frankfurt, Germany. This long-wave radio-signal (DCF77)
is based on atomic clocks and contains time and date information. The
WS8426 automatically synchronizes with this master clock radio-signal and
when necessary adjusts the positions of second, minute or hour hands of the
clock.
Due to its nature, the radio-signal can be received indoors. However, it should
be noted that the signal is weakened by the presence of concrete and metal.
Therefore the clock must not be installed in concrete basements or inside
metal cages. In large concrete office buildings or apartments, the clock should
be located near a window for better reception.
Also avoid installing the clock near strong magnetic fields or other devices
that generate a lot of electrical noise (e.g. engines).
