3. Setup

3.1 Battery Installation

Locate the battery compartment on the back of the alarm clock.
Open the battery compartment cover.
Insert the required batteries (batteries are not included) according to the polarity indicators (+ and -).
Close the battery compartment cover securely.

3.2 Initial Time Synchronization (DCF77)

Upon battery installation, the clock will automatically begin searching for the DCF77 radio signal to synchronize the time. This process may take several minutes.

Place the clock near a window for optimal signal reception.
A radio mast icon will appear on the display, indicating signal reception.
Once synchronized, the icon will become solid, and the correct time will be displayed.
The clock will attempt to synchronize automatically every hour, or at specific times (e.g., 2 AM UK time, which is 1 AM UK time for the Frankfurt signal).

3.3 Manual Time and Date Setting

If automatic synchronization is not successful or if you are outside the DCF77 signal range, you can set the time and date manually.

Press and hold the TIME button until the hour digits begin to flash.
Use the 12/24 or °C/°F WAVE buttons to adjust the hour.
Press TIME again to confirm the hour and move to the minute setting.
Repeat step 2 and 3 for minutes, year, month, and day.
After setting the date, the time zone adjustment will appear. Use 12/24 or °C/°F WAVE to set the offset (e.g., -1 for UK time if the clock defaults to Central European Time).
Press TIME to exit manual setting.

6. Troubleshooting

Problem	Possible Cause	Solution
Clock does not display anything or display is dim.	Batteries are low or incorrectly inserted.	Replace batteries with new ones, ensuring correct polarity.
Clock does not synchronize with DCF77 signal.	Poor signal reception due to location, interference, or distance from transmitter.	Move the clock to a different location, preferably near a window and away from electronic devices. Ensure the clock's back or front is facing towards Frankfurt (South East from UK). Initiate a manual signal search by pressing the °C/°F WAVE button. Set the time manually if automatic synchronization is consistently unsuccessful.
Incorrect time displayed after synchronization.	Incorrect time zone setting.	Adjust the time zone offset manually as described in Section 3.3.
Alarm does not sound.	Alarm is not activated or alarm volume is too low (if adjustable).	Ensure the alarm clock symbol is visible on the display. Press ALARM ON/OFF to activate. (Note: This model has a fixed alarm sound).
Temperature display shows "00" or incorrect readings.	Sensor malfunction or internal error.	Remove and reinsert batteries to perform a soft reset. If the problem persists, contact customer support.
