Where is the Serial Number on my P-TS7

Where is the serial number located on a P-TS7?

The serial number on a P-TS7 is on the back of the unit on a white sticker. 

If the unit is wall or rack mounted, you must first remove it from the wall.  This can be done by firmly grasping the edge of the screen and pulling it towards you, then tilting the bottom edge up. The video below shows the removal process.
