6.4.1 Note on radio-controlled time
The time base for the radio-controlled time is a caesium atomic clock operated by the Physika-
lisch 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 signal DCF-77 (77.5 kHz) and has a transmitting range of approximately
1,500 km. The adjustment to Daylight Saving Time (summer/winter time) is automatic. In Daylight
Saving Time the DST symbol is shown on the display. The reception quality depends mainly on geo-
graphic location. Normally there should be no reception problems within a 1,500 km radius around
Frankfurt.
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 window to improve reception.
• During night-time, the atmospheric interference is usually less severe and reception is possible in
most cases. A single daily reception is adequate to keep the accuracy deviation under 1 second.
7. Operation
• Important: Buttons will not function while scanning DCF or transmitter signal, unless they are well
received or stopped manually.
• During the operation, all successful settings will be confirmed by a brief beep tone.
• Press and hold the +/°C °F or -/RCC button in the setting mode for fast mode.
• The device will automatically quit the setting mode if no button is pressed for 20 seconds.
