Camilo, The modules in the MTR2000 station are not user-serviceable, so the field service manuals do not contain schematic diagrams. If you believe that the receiver module is defective, you should send it to the Motorola Infrastructure Depot for repair. I currently have six MTR2000 stations in service, but have never seen the problem you describe.
