SainSmart P5 Pure Morning Air Quality Monitor

So the listing here on Massdrop says "It has a 2.8-inch LCD screen, which displays information in real time and can be customized to suit your needs" how the hell do you customize it? There are no buttons on the unit itself and scouring the SainSmart I cannot locate any software....what am I missing?

No logging and no reports on whether the magic number it provides is at all accurate, I'll pass.
