•  When setting the Back Cover Assy on the Engine Frame Assy, check that the camera lid is in the 
closed position. If the camera lid is not closed, the camera switch on the 2

 PWB assy will break. 
•  When setting the Engine PWB on the Engine Frame, make sure that the key lock switch in the Engine 
Frame is pushed towards the top half of the phone. If the key lock switch is not in the correct 
position, the switch on the PWB will break. 
•  When assembling the UI (that is, Slide Assy, UI-FPC and the Display), you must use the SS-157 
Assembly Jig. Without the SS-157 tool, placing the UI-FPC is difficult.
