If removing and reassembling the Shield Plate Front for some 
reasons, be sure to follow the steps below. 
 Removing Shield Plate Front
1. Peel off the acetate tape and remove the grounding spring 1,2.
2. Bend the four protrusions of each of the two holes outwardly with a 
flat-head precision driver or the like and remove the Shield Plate Front.
NOTE. After removing, be sure to straighten the protrusions of 
the holes to restore their original state.
 Reassembling Shield Plate Front
1. Insert the two holes of the plate over the dowels on the base 
frame as far as they will go. 
2. Install the grounding spring 1, 2 and attach a 20 x 18 mm piece of 
acetate tape positioning it as described/shown below.
  • Leaving a space of 5mm from the edge (A), attach the right 6-
7mm-width portion of the tape to the Shield Plate Front. Fold 
the tape along the edge (B), and wrap the acute edge of the 
plate. Be careful not to let the tape run over the frame edge. 
NOTE 1. After reassembling, make sure the plate is kept in 
absolute contact with the frame.
NOTE 2. When replacing the Base Frame, remove the Shield Plate 
Front from the current Base Frame and reinstall it to a 
new one as the Base Frame supplied as an ASP does not 
include the part.
