You technically can't change the "Home position" but you can set up the camera to default to another location right after it does its start up dance and ends up at the home position. This is done by setting the IR preset "0". This is done by moving the camera to the location you wish, pressing the "preset" button on the IR remote, and pressing "0". This should have saved your preset "0" to be the location your camera defaults to after powering on.
