Operation Instruction

Connecting the battery and the plug which joint to heated piece.

The battery indicator

1)  Without load—press ON/SETUP, Power LED is red ,then the battery power is about 90%

2)  Without load—press ON/SETUP, Power LED display orange, then the battery power is about 60%

3)  Without load—press ON/SETUP, Power LED display green,then the battery power is about 25%

Five-steps intelligent power output Connecting load

1)   Press ON/SEUTP,when power LED is red ,the power output is 98%.

2)   Press ON/SEUTP button,,when LED display orange,the power output is about 75%.

3)   Press ON/SEUTP button,when,LED display green,,the power output is about 50%

4)   Press ON/SEUTP button,when,LED display lights flashing,,the power output is about 25%

5)   Press ON/SEUTP button,when LED lights turned off,no output power.The battery stops working and    shutdown.

6)   Input AC100V—240V 50-60HZ;Output DC 8.4v 1.0A

7) When the charger red LED turns into green,the battey is charging full.
