6. Working Principle
The clock 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 clock 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).
