*2: It depends on the system. The power supply error suitable for the product is defined.
*3: For details, refer to ERROR STANDBY CAUSE on the adjustment process screen.
*4: If the boot section is abnormal, there is no flashing (flashing disabled).

Outline: Communication/Power failure detected by the monitor microprocessor (IC2002) is stored on EEPROM, states can be confirmed in the
adjustment process mode.
Location: Page 1/21 of the adjustment process mode: MONITOR ERR CAUSE “0” if there is no error. It is cleared to 0 on the page (2/21) of the
adjustment process mode.
