Usage Tips: 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 slot. 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). The clock receives the radio signal, a process that takes 1–8 minutes. After receiving the time, the hands automatically turn to the correct position and begin normal operation. Mandatory reception / automatic reception: If you press and hold the REC button for more than 3 seconds, the hour, minute, and second hands stop immediately and enter forced reception mode. If the correct time is not received within 8 minutes, the clock resumes running at the previous time. If the correct time is received within 8 minutes, the hour, minute, and second hands first return to zero, then adjust to the correct time while updating the internal reference time.
