1) Completely back up the memory information in the robot controller by using the RT ToolBox 2. (This must
be performed as a preventive measure in case the contents of the internal memory are destroyed while

Also turn off the supplying source power switch at the controller.
If that is not right, there is danger of the electric shock.

information residing in the controller (the information is in the memory cassette).
Although the program information (***.mb5) is copied into the memory cassette, the parameter information
(***.prm) is still stored in the control unit.
