6.3 Radio-controlled time reception

• Three minutes after the base station has completed the search for the transmitter, the device starts scanning the DCF signal (radio signal) and the DCF reception symbol flashes.

• When the time code is successfully received after 3-12 minutes, the radio-controlled time, the date and the DCF symbol will be shown steadily on the display.

• You can also start the initialization manually.

• Press and hold the + and – button at the same time.

• The DCF reception symbol will be flashing.

• The DCF reception always takes place hourly between 1:00 and 5:00 o'clock in the morning. If the reception is not successfully received until 5:00 o'clock, the next DCF reception attempt will happen at 1:00 o'clock in the following morning.

• If the clock cannot detect the DCF-signal (e.g. due to interference, transmitting distance, etc.), the time can be set manually. The DCF reception symbol disappears and the clock will then work as a normal quartz clock (see: Manual settings).

• There are 4 different reception symbols: Radio waves are flashing - reception is active Radio waves stop flashing - reception is successful Transmission tower - no DCF reception No symbol - time is set manually

6.4 Note on radio-controlled time

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 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 DST is shown on the display. The reception quality depends mainly on geographic loca- tion. 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

• 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.

• Press and hold the + or – button in setting mode for fast mode.
