Found this out there. Pretty simple to follow.
1. Press Red start button (without Layard = Wake up ski)
2. Insert Lanyard and hold down the IBR lever.
3. When IBR Override mode is displayed in the screen, keep IBR lever pressed and press set.
4. Once in override mode (with IBR lever pressed) toggle VTS buttons up or down. If needed all the way up, press and hold.
5. When you reach the position desired, let go the IBR Trigger/lever. The ski will come out of IBR override mode, and the IBR will remain in position.
6. When complete, start the ski and then the IBR will return to position.
