Don't assume. I think to get machine hours you have to be in clinician mode. Press control knob and home button at the same time, then go to the information screen. Get the manual.
I have the manual. It appears that what I said is what needs to be done. It's a little confusing as it seems some of the info is not there but would be obvious if it was in front of you and tried it.
Just checked looks like you're right. Touch the setup button (with two little checkmarks) and the dial for 3 seconds. Then touch "i". After that the way it looks if it doesn't show up on the first screen I guess you would scroll using the dial. At least that's all i can figure out from it.
Looks like you've got it. Maybe someone with a S9 can confirm where Machine hours are found.
Even if you don't get that far, you still have valuable information as you will hear the machine being manipulated. I think you're in good shape to discuss it and pick up if the deal is real or not, and that's really the point.
Actually one need not enter clinician mode. Press i. Then rotate knob 2 clicks. Run hours at top of list.
Rotate knob back 2 clicks; then push i to back out.
