System used together with any Scorpio Head. The "MDB" is powered from the head and by setting on the head control the option "Internal or external of any of the channels (Focus, Iris or Zoom) those can be controlled from same head control. This way the focus puller controls the focus by radio and the operator controls the zoom and/or the iris from the head control.
For this function, switch on the Hand Unit while pressing "SEL" button and choosing the configuration mode of the Hand Unit, in this case will be "CCU+Radio", the next step will be to determinate which channel we want to assign to the Hand Unit and which one to the control, then when switching on all the equipment you will have split the functions. The channel chosen for the control can be memorized from the memory settings of the control.
This configuration is also used, having all the devices in channel 0, to memorize the movements of the Focus, Iris and Zoom together with the movements of the head.
