Appendix B: Disabling Auto
Function
The oscilloscope has the ability to disable the Auto button that
would automatically setup the scope to display a signal,
circumventing the need to know how to set up scope parameters.
This feature could be used by educators as a teaching tool for basic
oscilloscope operation.
To receive information on how to disable this Auto button function,
