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.
Between the left and right magneto ignition system alert indicators is a yellow
rpm
Synchronization indicator
. This small yellow indicator is illuminated when there is a
difference of more than 50 rpm between the right and left tachometers.
This indicator also may flicker during extreme rpm excursions of the engine.
OPERATION BUTTONS
There are three panel buttons. Each button has two modes of operation.
PRESS-AND-HOLD operation mode
(press and hold for more than 2/3 of a second)
This operation mode is placarded above each button.
