[amsat-bb] Alliance U-110 (Maybe U-100) Sync

I've got an Alliance U-1xx (not sure which, I thought it was labeled, but I cannot find it). Reading an online manual says if the light stays on after rotating, the rotor and control box should be re-synced and to follow the instructions on the bottom of the control box. I don't have those instructions. Does anyone know how to re-sync this rotor?

Thanks, Joel - W4JBB
