Page 1 of DV-535 Manual Region change???

Hello, I just bought a Pioneer DV-535 multiregion, I have it tested the automatic region chane on 2 DVD`s a R1 and an R4, and In receive a paper sheet with instructions to change the region manually, in case you have to do this, it says to turn on the equipment, to got to the general menu an select basic, later press display and it will appar the region information, then it says to press condition and next the region number, it says it should change region and disappear the region information window, so you can check it later pressing display, wqell it does not dsappear and it does not seem to change anything, do you know what is wrong??, is it the instructions??, sure I hope you can clarify this question for me ... thanks ...
