Repair and Replacement Procedures
Removing and Replacing the Case Group Parts
7-
Combining the Front and Rear Cases
1. Install a new gasket on the speaker side panel being careful not to stretch 
it or to damage it in any way. Also, make sure there is no slack in the 
gasket. A new gasket is provided in the Repair and Re-assembly Kit (the 
speaker side panel uses the larger of the two gaskets provided). If an old 
gasket must be removed, carefully remove it with tweezers being careful 
not to damage the groove.
2. If a new gasket has not been installed on the I/O side panel, install it at 
this time. It will be necessary to remove the I/O side panel from the A5 
System board. Refer to “Replacing the I/O Side Panel, Doors, and Gasket” 
on page 120 for instructions.
3. Refer to Figure 7-14. Position the front and rear cases side-by-side as 
shown.
4. Plug the battery cable, W15 into the A5 System board as indicated.
