Figure C-10. Routing of wire harness

NOTE: For key sheet

1. Before attaching a new key sheet, wipe off

remaining adhesive on the door screen surfaces
completely with a soft cloth soaked in alcohol.

2. When attaching the key sheet to the door screen,

adjust the upper edge and left edge of the key
sheet to the correct position of door screen.

3. Stick the key sheet firmly to the door screen by

rubbing with soft cloth not to scratch.

NOTE: For CPU unit

Handle the CPU unit carefully so that the ribbon
cable does not come off. Because the ribbon cable
is glued on the LCD and the printed wiring board
only by heated paste.
