Removing the Control Panel Board
1. Follow the procedures on page 4-11 to remove the LCD and Backlight Boards. If the unit
you are servicing has a Sampling Board, follow the procedure on page 4-9 to remove it.
2. The Control Panel-to-Keyboard Scanner Board flat ribbon cable is soldered into the
Control Panel Board. Remove the cable locking clip and disconnect the flat ribbon cable
from the Keyboard Scanner Board, location J705.
3. The enclosure support wall secures the front edge of the Control Panel Board to the top
enclosure. Remove the enclosure support wall screws, and set the wall aside.
Note: If you are servicing a K2600, there are seven screws securing the enclosure support
wall. If you are servicing a K2600X, there are eight screws.
4. Once the enclosure support wall is removed, you will notice that the Control Panel Board
also has adhesive-backed black felt that secures the front edge of the board to the top
enclosure. Peel back the black felt to release the front edge of the board.

Replacing the Control Panel Board

up slightly to verify that the spinknob and switch caps are correctly positioned through
the openings provided for them in the top enclosure.
