Radio-controlled alarm clock
• If the clock cannot detect the DCF-signal (e.g. due to interfer-
ence, transmitting distance, etc.), the time can be set manually.
The clock will then work as a normal quartz clock. (see: Manual
settings).
Radio-controlled time reception
The time base for the radio-controlled time is a caesium atomic
clock operated by the Physikalisch Technische Bundesanstalt based
in Braunschweig (Brunswick), Germany. It has a time deviation of
less than one second in one million years. The time is coded and
transmitted from Mainflingen near Frankfurt via the frequency sig-
nal DCF-77 (77.5 kHz) and has a transmitting range of approxi-
mately 1,500 km.
Therefore, please note the following steps:
• The recommended distance to any interfering sources like com-
puter screens or TV sets is at least 1.5 - 2 meters.
