Need instructions for the segawe 5 in 1 machine! Galvanic -positive/negative

Segawe 5 in 1 high frequency/galvanic/vacuum machine - spa/facial upc 700161255
Please help explain the details of using this machine! MOST I have been able to figure out through a ton of research but one of the main features I purchased this for galvanic use - except there are two functions - positive and negative and they perform opposite things step 1 opens pores for extraction and application of product and the other closes and tightens the pores (2nd step) 'locking' in the product and reducing outside elements from entering the pores - this machine has a 'push' button for negative/positive - I have no idea which way is which????
