Self-Diagnostic Test Lo - Panasonic JB-3300 Technical Manual

Self-Diagnostic Test
When power is supplied to the system the MPU performs a self-diagnosis
starting at address FFFFO (in hex) in ROM.
When an error is detected, a warning sound is generated or a warning
message is displayed on the screen.
The power-on time self-diagnosis flow is shown in Figure 9-20.
The RAM read/write check is not carried out only if the ESC key on the
keyboard is pressed at the power-on time.
Table 9-1 lists self-diagnostic error messages.
