4.1 Battery Installation

1. Open the battery compartment cover on the back of the clock.
2. Insert two AA batteries (not included) according to the polarity indicators (+/-).
3. Close the battery compartment cover securely.

4.2 Initial Power-On and DCF Signal

Upon battery installation, the clock will power on. If you are in Germany, the clock will automatically attempt to receive the DCF radio signal for time synchronization. This process may take several minutes. A signal icon will flash during reception and become solid upon successful synchronization.

If you are outside Germany or prefer manual time setting, you must disable the DCF function.

4.3 Disabling DCF (Outside Germany)

To disable the DCF function, press and hold the 'WAVE' button until the DCF signal icon disappears from the display. This allows for manual time and date setting.

4. Repeat steps 2 and 3 for minutes, year, month, day, and 12/24 hour format.

6. Maintenance

6.1 Cleaning

Wipe the clock surface with a soft, dry cloth. Do not use abrasive cleaners, solvents, or chemical sprays, as these may damage the display or casing.

6.2 Battery Replacement

When the display dims or functions become erratic, it is time to replace the batteries. Open the battery compartment, remove the old batteries, and insert two new AA batteries, ensuring correct polarity. Dispose of old batteries responsibly.

7. Troubleshooting

• No Display / Dim Display:
  Check battery installation. Ensure batteries are inserted with correct polarity. Replace batteries if they are old or depleted.
• Incorrect Time:
  If in Germany, ensure the DCF function is enabled and the clock is in a location with good signal reception. If outside Germany, ensure the DCF function is disabled and manually set the time and date as per section 5.1.
• Alarm Not Sounding:
  Verify that the alarm is activated (check for the alarm icon on the display). Ensure the alarm time is set correctly.
• DCF Synchronization Failure:
  Move the clock to a different location, preferably near a window and away from electronic devices that may cause interference. If persistent, disable DCF and set the time manually.
