Use the jog wheel to select CONFIG in the menue, then calibrate the touchscreen.It's a resistive touch surface so you'll need something like a Qtip.

Hi all.
I just got a new NanoVNA-H4 from GigaParts. It wasn't sealed so that is a red flag to me.? However, everything is there.? When I turn it on I see the intro screen for about 10 seconds and then it changes to a smith chart.? When I touch it a menu comes up on the right but I cannot select anything.? I can press on the smith chart and it goes away or reappears but that is all I can seem to do.? Any ideas? I have tried my finger and the pick they sent.
Thanks. David
