I downloaded the manual and searched but could not find a satin stitch. Any machine that has infinitely variable stitch length and infinitely variable stitch width can do a satin stitch, but this machine looks like it has only pre-set stitches. Even if one of those pre-sets is a satin stitch, it may not be adjustable.
Edit: I found it on Amazon, and it says in the description that stitch width and stitch length are not adjustable. It might be possible to use one of the buttonhole settings for satin stitch, though. Here is the Amazon description with 4 reviews:
