Getting started

• Insert a new battery 1,5 V AA, ensure that the battery polarity is correct.
• The device is ready for use.

Reception of the DCF frequency signal

• The clock's hands move to 12 o'clock.
• The clock will now scan the DCF frequency signal
• When the time code is received successfully after 3-12 minutes, the radio-controlled time is displayed steadily on the display.
• The DCF reception always takes place daily at 1:00 and 3:00 o'clock in the morning.

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 Braunschweig. 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. 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 reception is adequate to keep the accuracy deviation under 1 second.

MSET button - Manual setting of the clock

• If the clock cannot detect the DCF-signal (for example due to disturbances, transmitting distance, etc.), the time can be set manually. The clock will then work as a normal quartz clock.
• Press and hold the MSET button for three seconds.
• Press and hold the MSET button until the desired time is indicated.
• Press the button briefly the clock's hands will move minute by minute.
• The clock's second hand stops at 12 o'clock.
• After 15 seconds, the clock's second hand will move forward again.
• The manually set time will be overwritten by the DCF time when the signal is successfully received.

REC button

• Manual initialization can be helpful.
• Press and hold the REC button for three seconds.
• The clock's second hand stops at 12.00 o'clock.
• The clock will scan the DCF frequency signal.

RESET button

• Use a pin to press the RESET button if the device does not work properly.

Fixing

• You can attach the device with a nail at the respective location using the wall mounting hole.

Care and maintenance

• Clean your instrument with a soft damp cloth. Do not use solvents or scouring agents.
• Remove the battery if you do not use the product for a long period of time.
• Store your clock in a dry place.

Energy saving feature

• To reduce battery consumption, the clock's second hand stops daily between 10 p.m. and 6 a.m.

Battery replacement

• Change the battery as soon as the clock's function becomes weak and the clock's second hand stops during the day (between 6 a.m. and 10 p.m.) at 12 noon.
• Insert a new battery 1,5 V AA. Ensure that the battery polarity is correct.

Troubleshooting

Problems	Solution
The clock's hands stand still	Ensure that the battery polarity is correct Change the battery
The clock's second hand stands still	6 a.m. until 10 p.m.: Wait for the reception of the radiocontrolled time Change the battery 10 p.m. until 6 a.m.: Energy saving feature
No DCF reception	Press the REC button for three seconds and start the initialization manually Wait for attempted reception during the night Choose another place for your product Manual setting of the clock Check if there is any source of interference Restart the device according to the manual
Incorrect indication	Use a pin to press the RESET button Change the battery

If your device fails to work despite these measures contact the supplier from whom you purchased it.
