Static Return to Off, basically incorrect sequencing of controls/startup. On the Wave, this normally means trying to operate without standing on the footpedals, having the gates open on a machine that is set to require them closed for operation, having hands on the controls when keying on or the Base/Platform switch on the service pod is set to Base. If you are doing everything in the correct sequence, you need to check footswitches, throttle/steer pots and hand sensors.

Sro means static return to off.
So some switch that is normally open is closed or vice versa. Typically is deadman switches

Hi did you have any luck with this code? I have found it to be SRO but don't know what SRO means, and customer is deserpate for this to be working asap
