• 7. Power supply pay attention to the positive and negative poles, the power supply DC voltage is 5V.
• 8. Check for solder shorts and solder joints. This phenomenon is common.
• 9. If the display is abnormal or the time is not gone, remove the DS1302 and buttons. Battery, then plug in the DS1302, do not plug in the battery, and then power on, Put the battery on after normal.
