Radio-controlled alarm clock
It has a time deviation of less than one second in one mil-
lion years. The time is coded and transmitted from Main-
flingen near Frankfurt via the frequency signal DCF-77
(77.5 kHz) and has a transmitting range of approximately
1,500 km.
Therefore, please note the following steps:
• The recommended distance to any interfering sources
like computer screens or TV sets is at least 1.5 -
2 meters.
• Within concrete walls (reinforced with steel) such as
basements, the received signal is naturally weakened.
In extreme cases, please place the unit close to a win-
dow to improve reception.

• During night-time, the atmospheric interference is usu-
ally less severe and reception is possible in most cases.
A single daily reception is adequate to keep the accura-
cy deviation under 1 second.
