Quiet Test Mode

Quiet Test Mode (also referred to as Low Speed Exercise Mode) runs the generator at a lower RPM during the scheduled exercise cycle, which results in a quieter run. Quiet Test Mode is recommended to generator owners who prioritize quiet generator operation. Quiet Test Mode is not available on all generator models.
