Radio-controlled time reception
The time base for the radio-controlled time is a Caesium Atomic
Clock operated by the Physikalisch Technische Bundesan-
stalt Braunschweig. 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 frequency signal DCF-77
(77.5 kHz) and has a transmitting range of approximately 1,500
km. Your radio-controlled clock receives this signal and converts
it to show the precise time. Changeovers from summer time or
winter time are automatic. The quality of the reception
depends mainly on the geographic location. Normally there
should be no reception problems within a 1,500 km radius
around Frankfurt.
Please take note of the following:
• The radio-controlled time receiver is built inside the trans-
mitter. It is recommended to keep distance to any interfering
sources and ferro-concrete buildings.
• The outdoor transmitter will scan the DCF signal and transmit
it to the weather station. When the signal is received success-
fully the DCF time and the symbol will appear on the display.
If the reception is not successful, the DCF reception symbol
disappears, but the DCF time reception will be repeated
again.
• The clock automatically scans the time signal at 4 a.m., 5 a.m.
and 6 a.m. every day to maintain accurate timing. During
nighttime, the atmospheric disturbances are usually less severe
and reception is possible in most cases. A single daily reception
is adequate to keep the accuracy deviation below 1 second.
