Hello, all.  Does anyone know where the lithium coin cell is located on the E4440A PSA SpecAn?  I've got the case and the inside cover off and there is a diagram on the top of the inside cover showing the power supply, IF assemblies, etc but nothing showing the processor board or the location of the battery.  Thanks for your time
