CLOCCO – Wood style radio-controlled alarm clock with large LED digits
7. Operation
7.1 Manual settings
• Important: The device cannot be operated during the DCF time-signal reception.
• Press and hold the UP or DOWN button in setting mode for fast mode.
• The device will automatically quit the setting mode if no button is pressed for 10 seconds.
7.1.1 Set mode
• Press and hold the SET button in normal mode for three seconds.
• d-1 (default) will be flashing. Press the UP or DOWN button to adjust the display mode.
• Press the SET button to make the settings in the following sequence: The automatic dimming function (A-of - default), the DCF reception (dCF 1 -
default), the hours, the minutes, the year, the month and the day). Press the UP or DOWN button to adjust it.
• Confirm the setting with the SET button.
• Once the DCF time signal is successfully received and the DCF reception is activated (dCF 1), the manually set time is overwritten.
• 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.
