2. Setup
2.1 Unpacking and Included Components
Carefully remove all components from the packaging. Please ensure the following items are present:
- TFA Dostmann CLOCCO 60.2549.08 Alarm Clock
- Power Adapter
- 1 x CR2 Battery (for settings backup)
- Instruction Manual
2.2 Power Supply
The CLOCCO alarm clock operates primarily via the included power adapter. The CR2 battery serves as a backup to retain settings during power outages.
- Insert the CR2 battery into the designated battery compartment, observing the correct polarity (+/-). This battery ensures your settings are saved if the main power is interrupted.
- Connect the power adapter cable to the DC input port on the back of the alarm clock.
- Plug the power adapter into a standard electrical outlet. The display will illuminate.

2.3 Initial Time Synchronization
Upon initial power-up, the alarm clock will automatically attempt to synchronize with the DCF77 radio signal (atomic clock in Frankfurt, Germany). This process may take several minutes to a few hours, depending on your location and environmental conditions.
- Place the alarm clock near a window, away from electronic devices that might cause interference.
- A flashing antenna symbol on the display indicates that the clock is searching for the radio signal.
- Once synchronized, the antenna symbol will become solid, and the correct time will be displayed. The clock will automatically check and adjust the time, typically between 2:00 AM and 4:00 AM daily.
- If synchronization fails, you may need to manually set the time (refer to Section 3.1).
3. Operating Instructions
3.1 Display Modes and Manual Settings
The CLOCCO alarm clock offers various display modes and manual adjustment options:
Figure 2: Feature diagram showing display modes and controls.
- Switching Display Modes: Press the "SET" button (usually located on the back or top) to cycle through display modes: Time, Date, Day of the Week, Indoor Temperature, or an automatic cycle between these.
- Manual Time/Date Setting: If radio synchronization is unavailable or undesired, press and hold the "SET" button until the time digits flash. Use the "UP" and "DOWN" buttons to adjust the hour, then press "SET" to confirm and move to minutes, then date, and so on. Press "SET" again to exit manual setting mode.
- Temperature Unit: The temperature is displayed in Celsius (°C). There is no option to change to Fahrenheit.
3.2 Setting the Alarm
To set the alarm time:
- Press the "ALARM" button (usually on the back or top) once to display the current alarm time.
- Press and hold the "ALARM" button until the alarm hour digits flash.
- Use the "UP" and "DOWN" buttons to adjust the desired alarm hour. Press "ALARM" to confirm.
- The minute digits will flash. Use "UP" and "DOWN" to adjust the alarm minutes. Press "ALARM" to confirm.
- To activate or deactivate the alarm, press the "ALARM" button briefly when the alarm time is displayed. An alarm icon will appear/disappear on the display.
3.3 Dimming Function and Sound Activation
- Automatic Dimming: The display brightness automatically reduces between 7:00 PM and 6:59 AM to prevent excessive light during nighttime hours.
- Manual Brightness Adjustment: (If available, typically via a dedicated button or holding a button) Some models allow manual adjustment of brightness levels. Refer to the specific button labels on your device.
- Sound-Activated Display: When operating on battery power (if applicable) or in a specific mode, the display can be set to turn off and only illuminate when a sound is detected (e.g., a clap) or when the clock is touched. This conserves energy and reduces light pollution. Consult your device's specific button for this feature (e.g., "DOWN" button for 5 seconds as mentioned in a review).

4.2 Battery Replacement (CR2 Backup Battery)
The CR2 battery is primarily for backup. If you notice settings are not retained after a power interruption, it may be time to replace this battery.
- Locate the battery compartment on the back or bottom of the device.
- Open the compartment cover.
- Remove the old CR2 battery and dispose of it according to local regulations.

5. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank or not lighting up. | No power, power adapter disconnected, or sound-activated display is active. | Ensure the power adapter is securely connected to both the clock and the outlet. If using sound activation, make a sound or touch the clock. |
| Radio-controlled time is not synchronizing. | Poor signal reception due to location, interference, or initial setup. | Move the clock closer to a window and away from other electronic devices. Allow several hours for synchronization. If issues persist, manually set the time. |
| Display is too bright or too dim. | Automatic dimming active, or manual brightness setting needs adjustment. | The clock automatically dims between 7 PM and 7 AM. Check if your model has manual brightness adjustment buttons. |
| Alarm does not sound. | Alarm is not activated or set incorrectly. | Verify that the alarm is activated (alarm icon visible) and that the alarm time is set correctly (refer to Section 3.2). |
| Settings are lost after power disconnection. | CR2 backup battery is depleted or missing. | Replace the CR2 backup battery (refer to Section 4.2). |
