I am getting the diagnostic error E5622 on my 11800. What does this indicate?
The error code indicates a communication problem with the Time Base Board and is usually caused by dead NVRAM batteries. There are two NVRAM chips on this board and they plug into a socket that has control and battery capabilities. When the batteries go dead you loose the Enhanced Accuracy Calibration data and receive this error message.
