32 < autions and Techniques for removing the SP Unit > In addition to the explanation on the previous page, there are some cautions and techniques for removing the SP Unit. 1 Use a pair of tweezers as a lever. Insert the tips into the upper side-slits ( in Rear View) and get the bottom side of the Shield. Push the tweezers down in the direction indicated by an arrow in Side View. - Rear View - Side View Tweezers SP UNIT Shield MP UNIT 2 Now one of the 18-pin connectors gets disconnected from the SP Unit by doing 1 so that it becomes easier to detach the SP Unit.
