RPM RANGES
The face of the indicator is placarded with the respective engine rpm operating range.
Additionally the engine operating ranges are indicated by the large green, yellow, and red
LEDs. These LEDs are located on the upper right corner of the indicator face.
MAGNETO-CHECK
Three small LED magneto system alert indicator lights are located within the "Status" aera on
the upper left corner of the indicator face.
The left and right red LED alert indicator lights, when illuminated, indicate, because of loss of
ignition signal to the tachometer, a possible malfunction of the respective left or right magneto
ignition system.
While performing a magneto check during engine run-up, the red alert indicator lights will
illuminate, thus identifying the grounding of the respective right or left magneto systems.
