Answer
it uses an 'eeprom'(electronically erasable programmable read only memory) chip to store all the settings and presets. keep searching, i find what info i need most of the time for free, but if the only way you can find costs a few bucks, well go ahead and get it. only thing i've had to pay for in years was a schematic for a mid 70's studio mixer. as far as replacing the eeprom, (is needed from time to time in some equipment, mainly tv's) you will have to have a schematic to identify it and get part number anyway. of course, i don't have any schematics, i'm retired.
