Removing the DFC3 Daughter Card
Step 6 Partially reinstall the cap nut, as shown in Figure 4, about 3 turns so that there is a space of about 1/8 inch (3 mm) between the bottom of the cap nut and the top of the DFC3 daughter card. The cap nut acts as a stop when you unseat the daughter card connector so that the DFC3 daughter card does not move horizontally and cause damage to the base board.

Step 7 With your left hand, lift slightly at the location shown in Figure 5. While lifting with your left hand, rock the DFC3 daughter card up and down with your right hand, no more than half an inch in either direction, to unseat the DFC3 daughter card from the module.
