Page 1 of CH402 Question & Hack

My buddy in America has a 402/2, USA Version. Any idea if the hack for UK models works on the US model?
Here by the way are my idiot-guide instructions for the CH402 - slightly more elaborate than other instructions:
Press the setup button on remote control. Display changes to SETUP MENU -- MAIN PAGE.
Press 1 3 6 9 on remote control, in order, one at a time. The display will not change.
Press left arrow, left arrow, left arrow, right arrow, The display flickers & re-displays.
Press down arrow to tab down to VERSION and press ENTER. The display changes to VERSION PAGE.
REGION CODE is highlighted in green and a number will be to the right, also in green.
Press right arrow and the number will be highlighted in pink. Press up arrow or down arrow to change as follows: 1 for Region 1, 2 for Region 2, 0 for Multi Region.
Press left arrow to highlight REGION CODE.
Press down arrow to go to MAIN PAGE and press ENTER.
The screen reverts back to SETUP MENU -- MAIN PAGE.
Press down arrow to go to EXIT SETUP.
Press ENTER.

That should change your tv screen back to normal.
