Configuration Register is a special CV that controls a number of character -

key shows DATA simply press the number key corresponding to the
feature you want to toggle off/on. For example pressing the key will
toggle NDOT off and on. The CV29 Value will automatically be calculat -

press the “WRITE” to write the configuration to the decoder.
