Automatically receive the time. After installing the battery, the hour, minute, and second hands will stop at 12 o'clock, and the time signal will be received within 8 minutes. Insert an alkaline battery (1.5V AA) into the battery compartment. The second hand rotates and stops when it points to 12:00 (the second hand returns to zero), then the minute hand starts to rotate. The hour hand points to 12:00, and the minute hand also points to 12:00 (hour and minute hands return to zero), receiving the radio signal. This process takes 1–8 minutes. After receiving the time, the hands will automatically turn to the correct position and start normal operation. Mandatory reception / automatic reception: If you hold down the REC button for more than 3 seconds, the hour, minute, and second hands will stop immediately and enter the forced reception state. If the correct time is not received within 8 minutes, the clock will continue to run at the previous time. If the correct time is received within 8 minutes, the hour, minute, and second hands will first return to zero and then adjust to the correct time, while updating the internal reference time.
