Screen Locked

To lock a screen, press the button. The current view stays locked and does not automatically return to the default screen after time-out. When the screen is locked, the image of a key appears on the UPS status summary screen just to the left of the status icon. See Figure 31.

Pushing any button returns the normal button function, unlocks the screen, and removes the lock symbol.
