5. Working principle
The WC3320 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 WC3320 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).
