If pressing the "Menu" button doesn't do it then it's probably broken.

Might be worth having a look at the PCB soldering,  crappy soldering is a common issue on cheap china stuff. The design works but they don't do QA/QC so stuff with obvious broken solder joints gets send out.

The buttons maybe soldered by hand, so that's a common fault when hand assembling them for cheap.

I have a Fnirsi TC3 and the scope took a second for the same type of stuff.

My guess is to move the Left and Right buttons, and you should see some form of indicator that one of the listed settings on the screen are selected. Once you figure that part out, then you probably just hit the +/- keys.

By the way. This device already has a thread.

Difficult to find because the name is not entirely clear.
Probably SCO_2_10M

When you get more familiar with it, maybe you could post some of your impressions?
