How to Use
1. Pull the white button on the backside for about 3s until it shows “1-U Inch and release it. Pull it again for 1s it shows “2-b Inch and release it. Pull it again for another 1s it shows “3-c Inch and release it. Pull it again for another 1s it shows “4-d Inch.
2. When it shows “1-U Inch, pull the white button for 3s then you can adjust the voltage admeasuring apparatus. Pull it for a longer time, the voltage goes up. Then pull it for another longer time, the voltage goes down. Do it again and again. To save and exit Automatically after the screen is twinkling.
3. When it shows “2-b Inch, you can change the type of battery.
