Mother board fatal error – Beeps on startup

Problems with your system’s mother board “fatal error” or “beeps on startup” on your Omniturn CNC lathe’s control can be caused by something as minor as a  bad connector or as major as a damaged chip.The information in this section is designed to help you find out problems if the system board is not  operating properly.Each time the system is powered on, the Power-On Self Test (POST)  diagnostic routine determined if any error occurs.Errors are communicated during system boot-up as either a series of beeps or as messages that appear  on the screen.Fatal errors do not allow the system to complete boot-up, and are usually signaled as a series of beeps.Non fatal errors allow boot-up to continue and result in error messages on the screen.
