7. Note for radio-controlled time DCF
The time base for the radio-controlled time is a caesium atomic clock operated by the Physikalisch Technische Bundesanstalt Braun-
schweig. 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 frequency signal DCF-77 (77.5 kHz) and has a transmitting range of approximately 1,500 km. Your radio-controlled
clock receives this signal and converts it to show the precise time. Changeover from summer time or winter time is automatic. In Day-
light Saving Time DST is shown on the LCD. The quality of the reception depends mainly on the geographic location. Normally there
should be no reception problems within a 1,500 km radius around Frankfurt.
Please take note of the following:
•
The recommended distance to any interfering sources like computer monitors or TV sets is at least 1.5 - 2 meters.
•
Inside ferro-concrete rooms (basements, superstructures), the received signal is naturally weakened. In extreme cases, please place
the unit close to a window to improve the reception.
•
During night-time, the atmospheric interference is usually less severe and reception is possible in most cases. A single daily recep-
tion is adequate to keep the accuracy deviation under 1 second.
8. Operation
• During the operation, all successful settings will be confirmed by a brief beep tone.
•
The device will automatically quit the setting mode if no button is pressed for a long period of time.
•
Press and hold the +/12/24 or -/°C/°F button in the setting mode for fast running.
8.1 Manual settings
•
Press and hold the MODE button in normal mode. The device will alert you with a beep. The hour digit will be flashing. Press the
+/12/24 or -/°C/°F button to adjust hours.
•
Press the MODE button to make the settings in the following sequence: Minutes, seconds, year, month, day and time zone. Press
the +/12/24 or -/°C/°F button to adjust it.
•
Confirm with the MODE button.
•
The manually set time will be overwritten by the DCF time when the signal is received successfully.
8.1.2 Setting of the time zone
• In the setting mode you can make the time zone correction (-12/+12).
•
The time zone correction is needed for countries where the DCF signal can be received but the time zone is different from the Ger-
man time (e.g. +1=one hour later).
