A cyclometalated transition metal complex very efficiently emits phosphorescent light and an organic electroluminescent device using the same. In a pre-operating system environment, the reference measurement can be compared with a golden measurement and a policy action can be applied if a variance is detected between the reference measurement and the golden measurement. In setup mode the controller scans a first portion of the substrate, receives the focus data and XY data, and stores correlated XYZ data for the substrate. The object downloading module informs the second user to download and install the communication application module, so a click-to-call icon is generated on a communication terminal of the second user.
