Questions & Answer
Q 1:The current knob has been turned,why can’t the current be adjusted?
A 1:You must connecte a load and the voltage setting cannot be 0, and then the current is adjusted
Q 2:Why isn’t the cooling fan working?
A 2:We installed a smart cooling fan with a built-in temperature control sensor that turns on when
the temperature reaches 50 degrees Celsius.
Q 3:I can’t choose the input voltage 220V or 110V?And the EU/AU/US/UK plug ?
A 3:This one support 220V 110V EU PLUG
Q 4:Scratches on the screen？
A 4:There is a protective film on the screen that can be peeled off.
