TIME BLOCK
– Radio-controlled alarm clock
• After a test run (11:11 until 00:00 appear on the display) the clock will scan the DCF fre-
quency signal and the DCF symbol flashes on the LCD. When the signal is received success-
fully after 3-10 minutes, the radio-controlled time appears.
• Please do not press any keys during signal reception.
• If the radio-controlled clock is unable to receive a DCF signal, further attempts will be
made every hour between 2 a.m. and 5 a.m. Therefore no alarm setting is possible
between 2:00 and 2:10, 3:00 and 3:10, 4:00 and 4:10 and 5:00 and 5:10.
• Should these attempts fail, a random time will appear on the display and the symbol dis-
appears.
• Manual initialization can be helpful. Press MODE button.
• In case the clock cannot detect the DCF-signal (for example due to disturbances, transmit-
ting distance, etc.), the time can be set manually. The clock will then work as a normal
quartz clock. (see: Setting of clock and calendar).
Radio-controlled time reception:
The time base for the radio-controlled time is a Caesium Atomic Clock operated by the
Physikalisch Technische Bundesanstalt Braunschweig which 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 approxi-
mately 1,500 km. Your radio-controlled clock receives this signal and converts it to show
the precise time in summer or wintertime. The quality of the reception depends greatly on
the geographic location. In normal cases, there should be no reception problems within a
1,500 km radius around Frankfurt.
Please take note of the following:
• Recommended distance to any interfering sources like computer monitors or TV sets is a
minimum of 1.5 - 2 metres.
• Within ferro-concrete rooms (basements, superstructures), the received signal is naturally
weakened. In extreme cases, please place the unit close to a window and/or point its front
or back towards the Frankfurt transmitter.
• During night-time, 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.
