CLOCCO – Wood style radio-controlled alarm clock with large LED digits

Symbol solid – signal is found

Symbol solid – reception is very good

• 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 sym-

bol disappears and the clock will then work as a normal quartz clock (see: Manual settings).

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. Your radio clock receives the signal, converts it and always

shows the exact time. The adjustment to Daylight Saving Time (summer/winter time) is automatic. 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 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.
