PAL to NTSC after a factory default

Here are the directions for bringing the AzBox from PAL to NTSC. After a factory default and reboot the receiver defaults to PAL. To change the format to NTSC do the following steps using the remote:

1) Reboot the receiver by the switch on the back of the unit. Wait until it powers up and the display is scrolling
2) Hit the Down Arrow 6 Times
3) Hit the OK button
4) Hit the Right Arrow 1 Time
5) Hit the Down Arrow 1 Time
6) Hit the Right Arrow 1 Time. You have now changed the display setting from PAL to NTSC
7) The receiver will ask you if you want to save your change and say YES

On my azbox ultra, which is being used exclusively for true fta, all you need to do is press the resolution button on the remote. Are those above instructions for other azbox receivers?
