The ignition flash is held back in order to use the set value in angular degrees in order to use the OT marking plus set value as a ignition setting value. Example: Your vehicle only has an OT marking and no further markings for early and late bureau. But the manufacturer specifies the data for early and late late. In this way, you set the ignition value in degrees at the rotary control of the device. If this value is set at the ignition, the OT marking would now be flashed. If this is not the case, turn the device control of the device until the OT marking appears. You can read this value from the device control of the device and know how the ignition is currently set and can thus correct the ignition in the corresponding direction. The ignition adjustment is infinitely varied from 0 to 6.
