6.1.2 Loading the Update Programs/Data to the Machine

If you want to update the current programs/data stored in the flash ROM on the main PCB or after
you replace the main PCB, load the update programs/data to the flash ROM.
Loading requires a PC/AT-compatible computer running Windows 98/98SE, Windows Me,
Windows 2000 Professional, or Windows XP Home/Professional.
CAUTION: During loading, do not turn the power off, interrupt loading, or load invalid data. If you
do so, loading will fail, causing the PCB to be unusable. You will need to replace the main PCB
and load update programs/data to a new PCB.
