The LX-300 contains a digital signal processor and built-in software. When you power-on ("boot") an LX-300, this software is automatically loaded. During the boot, it performs a number of diagnostic tests, initializes the hardware, and loads the latest control software.

If the boot software encounters any non-recoverable (fatal) errors, it will attempt to display the error. The following boot sequence description should assist you in identifying at which point the error occurred and what caused it.
