Outback Mate 3, GEN button not working

[Cult of Dionysus]

So I just had my Mate3 replaced (as the old one wasn't working with OpticsRE). The new one is doing well, except for the fact that when I hit the GEN button on the bottom left on the Mate3, nothing happens. Typically, on the old unit, I'd get to the Generator page. However, with the new one, nothing happens. Seems really strange.

Any insight or input would be much appreciated.

Thanks in advance.

Are you using a Radian?. Could the Mate have defaulted to a Mode that doesn't use a generator?

Actually, we need to take a step back. It turns out that none of the six function buttons on the Mate 3 are working. So Charger / Inverter / Gen on the left side and Events / Input / Favorites on the right side. If I press ANY of those six buttons, nothing happens. The four button at the bottom of the Mate 3 are working. And I can access and use the rotary dial button to access Settings.

What inverter are you interfacing with? Have you also posted on the Outback Power Forum?
