Field notes

The visible index pairs alarm explanations with manual-specific references, including Kohler TP-7092 and Cummins’ RS home-standby operator manual. Its sample entries distinguish easily confused cases—for example, four Cummins blinks from code 44, and Generac low-oil-pressure code 1300 from overspeed codes 1200/1205/1207; the brand directory lists 25 Generac codes and 12 each for Kohler and Cummins.
