STOP. DO NOT make changes to the front-panel settings that are not called out
in the procedures. Each verification procedure will require you to set the
oscilloscope to certain default s ettings before verifying functions. If you make
changes to these settings, other than those called out in the procedure, you may
obtain invalid results. In this case, just redo the procedure from step 1.
When you are instructed to press a front-panel or screen button, the button may
already be selected (its label will be highlighted). If this is the case, it is not
necessary to press the button.
