2. Initial Time Synchronization

After battery insertion, the clock will automatically attempt to receive the DCF radio time signal. This process may take several minutes:

1. The hands will move to the 12 o'clock position and then begin searching for the radio signal.
2. Once the signal is successfully received, the clock will automatically set itself to the correct time.
3. Place the clock near a window or in an open area for optimal signal reception during initial setup. Avoid placing it near electronic devices that may cause interference.

3. Manual Time Setting (If Radio Signal Unavailable)

In areas with poor radio signal reception, you may need to manually set the time. Refer to the back of the clock for control buttons:

• REC Button: Press this button to initiate a manual search for the radio signal.
• SET Button: If the radio signal cannot be received, press and hold the SET button to manually adjust the time. Each press will advance the minute hand.

4. Mounting

The clock is designed for wall mounting:

1. Select a suitable location on a wall, ensuring it is sturdy enough to hold the clock's weight (approximately 455g).
2. Use a screw or nail (not included) appropriate for your wall type.
3. Hang the clock using the integrated hanging hole on the back of the device.

Operating

Automatic Time Adjustment

Once the radio signal is successfully received, your TFA Dostmann wall clock will automatically:

• Maintain precise time accuracy.
• Adjust automatically for Daylight Saving Time (summer/winter time changes).

The clock will periodically check and update its time signal to ensure continuous accuracy.

Maintenance

Cleaning

To clean your clock:

• Use a soft, dry, or slightly damp cloth.
• Do not use abrasive cleaners, solvents, or polishing agents, as these can damage the glass cover or casing.

Battery Replacement

When the clock hands stop moving or the time becomes inaccurate, it is time to replace the battery:

1. Remove the old AA 1.5V battery from the compartment.
2. Insert a new AA 1.5V battery, observing correct polarity.
3. The clock will then attempt to resynchronize with the radio signal.

Troubleshooting

If you encounter issues with your clock, refer to the following common problems and solutions:

• Clock not setting time or displaying incorrect time:
  - Ensure the battery is new and inserted with correct polarity.
  - Press the 'REC' button on the back to initiate a manual signal search.
  - Move the clock to a different location, preferably near a window and away from electronic devices (TVs, computers, microwaves) that may cause interference.
  - Allow sufficient time (up to several hours) for the clock to receive the radio signal, especially during initial setup or after battery change.
• Hands are stuck or not moving:
  - Replace the battery with a fresh AA 1.5V battery.
  - Check for any obstructions preventing the hands from moving freely.
• Poor radio signal reception:
  - The radio signal (DCF77) is transmitted from Mainflingen, Germany. Reception can be affected by geographical location, building materials, and local interference.
  - Try placing the clock in different orientations or locations within the room.
  - If consistent reception is not possible, use the manual time setting feature.
