Symptoms

Round Push Buttons Do Not Work or the HOME Button on Touchscreen Does Not Work (Loss of Focus)

1. If there is a logged or snoozed event, press the yellow event box at the bottom of the screen or anywhere on the bottom banner. This will bring the focus back to the Machine Health application.
