2. Radio Wave Reception and Initial Time Setting
This clock automatically sets the time by receiving standard radio waves. After battery installation, the clock will attempt to receive the signal.
- Place the clock in a location where radio wave reception is optimal, typically near a window and away from electronic devices that may cause interference.
- The second hand will move to the 12 o'clock position and stop, indicating it is searching for the signal.
- Once the signal is received, the clock hands will automatically adjust to the correct time, and the digital display will show the current date. This process may take several minutes.

Note: If reception is difficult, try moving the clock to a different location or manually initiating reception by pressing the 'Reception' button on the back of the clock.
Operating Instructions
1. Silent Continuous Second Hand
The clock features a smooth, continuous second hand movement, eliminating the traditional ticking sound. This design ensures a quiet environment, ideal for bedrooms, studies, or offices.

The digital LCD display provides real-time information on temperature, humidity, and the date. You can select from three display modes using the buttons on the back of the clock:
- Mode 1: Fixed Calendar Display - The display will continuously show the date.
- Mode 2: Fixed Temperature/Humidity Display - The display will continuously show the current temperature and humidity.
- Mode 3: Automatic Switching Display - The display will automatically switch between calendar and temperature/humidity every 5 seconds.

Maintenance
1. Cleaning
To clean the clock, wipe it gently with a soft, dry cloth. Do not use abrasive cleaners, solvents, or chemical sprays, as these may damage the finish or internal components.
2. Battery Replacement
Replace batteries when the clock stops or the digital display becomes dim. Always replace both batteries at the same time with new, high-quality AA batteries. Dispose of used batteries according to local regulations.
Troubleshooting
- Clock not displaying correct time or not moving:
Check battery installation and ensure batteries are fresh. If the issue persists, manually initiate radio wave reception by pressing the designated button on the back of the clock. Ensure the clock is not near strong electromagnetic interference sources. - Digital display is blank or dim:
Replace batteries with new ones. Ensure the clock is not exposed to extreme temperatures. - Radio wave reception failure:
