3.1 Automatic Time Setting (DCF77)

The clock automatically receives the DCF77 radio signal from Frankfurt, Germany, ensuring precise timekeeping, including automatic adjustment for Daylight Saving Time (DST).

• After battery insertion, the clock will automatically search for the DCF77 signal. A radio tower icon will typically appear on the display during this process.
• Once the signal is received, the time will be set accurately to the second.
• If the signal is lost or weak, the clock may attempt to resynchronize periodically.

3.2 Display Information

The large XL display provides the following information:

• Time: Current time in hours and minutes.
• Date: Day and month.
• Day of the Week: Full display of the day of the week (available in 10 languages).
• Indoor Temperature: Current temperature in degrees Celsius.
• Indoor Humidity: Current relative humidity percentage.

3.3 Alarm and Snooze Function

The clock includes an alarm function with a snooze option.

• Refer to the detailed instructions in the included printed manual for setting the alarm time.
• When the alarm sounds, press the SNOOZE button to temporarily silence it. The alarm will sound again after a short interval.
• To deactivate the alarm, press the ALARM button.

3.4 Time Zone Setting

The clock supports a time zone adjustment feature (+23/-23 hours) to accommodate regions outside the standard DCF77 reception area or for specific local time offsets. Consult the full manual for detailed instructions on how to adjust the time zone.

4. Maintenance

• Cleaning: Wipe the clock surface with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Battery Replacement: Replace all 4 AA batteries when the display becomes dim or the clock stops functioning correctly. Always replace all batteries at the same time with new ones of the same type.
• Environment: Avoid exposing the clock to extreme temperatures, direct sunlight, or high humidity, as these can affect performance and lifespan. This product is designed for indoor use only.

5. Troubleshooting

• No Display/Dim Display: Check battery installation. Ensure batteries are inserted with correct polarity and are not depleted. Replace with fresh batteries if necessary.
• Incorrect Time/No Radio Signal: Ensure the clock is placed in an open area away from potential sources of interference (e.g., TVs, computers, large metal structures). Try repositioning the clock. The DCF77 signal is strongest at night.
• Inaccurate Temperature/Humidity: Ensure the clock is not placed near heat sources, vents, or in direct sunlight, which can affect sensor readings. Allow time for the sensors to stabilize after initial setup or relocation.
