< Cautions and Techniques for removing the DSP Unit >
In addition to the explanation on the previous page, there are some cautions and techniques for removing
the DSP Unit.
1 Use a pair of tweezers as a lever.
Insert the tips into the upper side-slits (A 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.

2 Now one of the 18-pin connectors gets disconnected from the DSP Unit by doing 1 so that it becomes
easier to detach the DSP Unit.
Lift and remove the DSP Unit and the Shield together.
Be careful not to give any stress to the 18-pin connectors on both sides when removing the DSP Unit
and the Shield.
