Need help CMER 434Z

I have in use EDM CHMER 434Z.

This machine has 100 fixed operating modes (so called S codes)

According to the manufacturer, for almost every treatment case, you can find and select the appropriate mode.

Each mode has 9 parameters, including the height and speed of periodic lifting of the electrode for flushing.

In all 100 modes, the lift height does not exceed 2 mm. At the same time, my specificity is such that I need a higher lift.

Can anyone suggest how to edit this S code or set the processing parameters manually?
