Image 3: Back View. This image shows the back of the alarm clock. It features a large battery compartment cover at the bottom. Above it, there is a small dial for setting the alarm time, labeled "SET", and a button labeled "WAVE" for manual radio signal reception. A small reset button is also visible.
Setup
- Battery Installation:
- Open the battery compartment cover located on the back of the alarm clock (refer to Image 3).
- Insert one (1) AA/LR6 battery, ensuring the correct polarity (+/-).
- Close the battery compartment cover securely.
- Initial Time Synchronization (Radio Control):
- After inserting the battery, the clock hands will perform a full rotation and then stop precisely at the "12" position.
- The alarm clock will then enter reception mode to synchronize with the DCF-77 time signal.
- This initial synchronization process can take up to 20 minutes. During this time, the hands will not move. It is crucial not to interrupt this process. The clock will automatically set to the correct time once the signal is received.
- For optimal reception, place the clock near a window and away from electronic devices that may cause interference.
Operating Instructions
- Setting the Alarm Time:
- Locate the alarm setting dial on the back of the clock (labeled "SET" in Image 3).
- Rotate this dial to move the small alarm hand to your desired alarm time.
- Activating/Deactivating the Alarm:
- Use the ON/OFF slide switch located on the right side of the casing (refer to Image 2).
- Slide the switch to "ON" to activate the alarm. When the alarm is active, the second hand will move to the "12" position and stop, enabling the "No Tick" silent operation feature.
- Slide the switch to "OFF" to deactivate the alarm. The second hand will resume normal sweeping motion.
- Snooze Function:
- When the alarm sounds, press the large button on top of the clock (labeled "LIGHT/SNOOZE").
- The alarm will pause for approximately 5 minutes before sounding again.
- Dial Illumination:
- Press the large button on top of the clock (labeled "LIGHT/SNOOZE") to temporarily illuminate the dial for easy reading in the dark.
- The clock also features luminous hour and minute hands for visibility in low light conditions.

Image 4: Illuminated Dial. This image shows the alarm clock's dial illuminated in a dark environment, demonstrating the effectiveness of the backlight feature activated by the top button.
- Automatic Summer/Winter Time Adjustment:
- The radio-controlled mechanism automatically adjusts for Daylight Saving Time (summer/winter time changes) overnight between 2 AM and 3 AM. No manual adjustment is required.
