Gently raise the front of the projector and push the tab that adjusts the stand upwards. This shall result in the stand extending out of the base of the projector.

If the stand does not entirely slide out of the base, grab the part of the stand that has been exposed and pull it until you have removed the entire piece from the base.

Keep pushing the tab upwards as you pull the stand out to ensure it is removed as smoothly as possible.
