What is Unidentified Alarm & CPU Error Guide about?

This document describes unidentified alarm occurrences or run CPU address errors on TCD 2 and TCD 3. For TCD 2, it occurs when unidentified codes are read by the alarm interrupt more than 3 times without an address error. For TCD 3, it occurs when the unidentified address accessed by the DOC-200 PCB is detected more than 3 times. It provides steps to check the +5V voltage, and potentially replace components like the GAL, EPLD, or FLASH MEMORY chip on the DOC-200 PCB to resolve the issues.
