Press [CLEAR] followed by [1][3][6][9] and one of the keys [0]...[8] corresponding to the region you want to set the player for (1 for Region 1, 2 for Region 2 and so on, press 0 for Region 0 or Region Free). Turn the player off then on again for the changes to take effect.

To verify the region code, press [SETUP] followed by [1][3][7][9]. A screen will then pop up with the firmware info and the current region code setting. Using [SETUP][1][3][6][9] did not work for me.
