Electronic calendar setting instruction:
1>. Power on, and press the power switch button. At this time, the screen will display normally and ring the bell, and then any button can stop the bell.
2>. Adjust the calendar and time: On the main interface, press the "ENTER" button once, and the "year" of the calendar flicker.

Find the 12H/24H jumper welding disc on the back of the circuit board, break it into 24 hours, and short connect it to 12 hours. Find Celsius/Fahrenheit jumper wire welding plate, disconnect Celsius and short connect Fahrenheit.After setting up and short circuit with tweezers.
