3.2 Initial Power On
Once connected to power, the LED display will illuminate. The clock may display a default time or require initial time setting.
4. Operating Instructions
4.1 Setting Time and Date
Refer to the buttons on the back or bottom of the clock. Typically, there are buttons labeled 'SET', 'UP', 'DOWN', or similar. Press 'SET' to enter time setting mode. Use 'UP'/'DOWN' to adjust hours, minutes, year, month, and day. Press 'SET' again to confirm each setting and move to the next. The display supports 12-hour and 24-hour formats.
4.2 Setting Alarms
The clock supports up to 3 independent alarms. Locate the 'ALARM' or 'A1/A2/A3' button. Press it to select an alarm (e.g., A1). Use 'SET' to enter alarm time adjustment and 'UP'/'DOWN' to set the desired alarm time. Confirm with 'SET'. The alarm sound is a gentle cuckoo sound. To activate/deactivate an alarm, press the 'ALARM' button repeatedly until the desired alarm indicator (e.g., A1 ON/OFF) is shown.

4.4 Energy Saving Mode (Clap Activation)
To conserve energy, the display automatically turns off after 30 seconds of inactivity. To reactivate the display, simply clap your hands or make a similar sound near the clock. The display will light up, showing the current time, date, and temperature.

5. Maintenance
5.1 Cleaning
Wipe the clock with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the surface. Avoid getting moisture into the electronic components.
5.2 Battery Replacement (CR2032)
The CR2032 battery is for memory backup only. If the clock loses time or settings after a power disconnection, the CR2032 battery may need replacement. Open the battery compartment, typically located on the back, and replace the old battery with a new CR2032 battery, ensuring correct polarity.
6. Troubleshooting
- Display is blank: Ensure the USB-C power cable is securely connected to a working power source. If in energy-saving mode, clap your hands to activate the display. Check if the CR2032 backup battery is correctly installed.
- Alarm does not sound: Verify that the alarm is set and activated (e.g., A1 ON). Check the alarm volume settings if available.
- Incorrect time/date: Re-enter the time and date settings as described in Section 4.1. Ensure the clock is receiving continuous power.
- Clap activation not working: Ensure the sound is loud enough and close to the clock. Check if the energy-saving mode is enabled.
