Replacing the Keyboard
To replace the keyboard, perform the following steps:
1. Connect the green wire to the spade connector on the keyboard.
2. Connect the keyboard ribbon cable to J201 on the control board.
3. Position the top of the keyboard so the four tabs on the top of the keyboard frame are
placed under the lip on keyboard well.
4. Press down on the base of the keyboard until each latch is latched.
The rubber keypad and/or keyboard assembly may be damaged if any key or LED
becomes trapped under the overlay while replacing the overlay. Make sure each and every
key and LED comes through its hole in the overlay.
5. Align the overlay with each of the keyboard keys and LEDs. Position your thumbs
along the front edge of the overlay near each end. Apply pressure on the overlay
toward the rear of the unit and then press down on the overlay. This is one continuous
motion. The front of the overlay should now be snapped into place. Snap the rear of
the overlay into place.
