Confirmation of firmware version and checksum
Before and after writing firmware, check the firmware version and checksum by using the self-diagnostic function
menu.
Start up the self-diagnostic function and select “25. ROM VER/SUM/PORT” menu. (See “SELF-DIAGNOSTIC FUNCTION”)
Using the sub-menu, have the firmware version and checksum displayed, and note down them.
Replaced parts Writing method using the USB Writing method using PC (RS232C)
