Komatsu service side of the monitor in Excavator. 

Just here to help.

I would replace the panel.

You probably got hold on the keys. Hold 4 then press 1, 2, 3 and then release 4. Or hold the enter key and then press 1,2,3,4 release enter. Let me know.

The enter key should be the check mark too.

The key pad is your A/C controls. Part blue and grey.

Unfortunately it didn’t seems to work for me. Ive tried both and got nothing

Hold the down gray arrow 123 or hold the upgrade Aero 123

Pc200-8 you cannot adjust. Cummins engines are preset. Older models you could.
