Can I change [Region] and [Country/Area] set at the time of installation?
Yes, you can.
Select [Start] - [All Programs] ([Programs] for Windows(R) 2000) - [Sony Picture Utility] - [Tools] - [Location Settings Tool], then set [Region] and [Country/Area].
Note
In PMB Portable Maintenance Tool, the [Region] and [Country/Area] information changed with [Location Settings Tool] is not effective. The [Region] and [Country/Area] information set at the time of installation is used.
