Sida 15 av 26

The indications left and right shows the error in the calibration or, alternatively, the force on the handle. Green corresponds to a low force, which means that the calibration is good and that Simplex will be ready for start. Red corresponds to a larger force, meaning that either a new calibration is needed, or the force needs to be removed from the handle.
Start
When the indication ready is shown, E-Drive can be started by activating one of the dead man’s switches. The left, right or both hands can be used. The switches have three positions. In the middle position they are activated. Simplex stops if both dead man’s switches are released, or if any switch is pressed to its third, fully depressed, position.
