MS-9200UDLS Keypad/Display Removal
Removal of the keypad/display is normally not necessary. If, however, it becomes
necessary to replace the keypad/display or access jumpers JP5 and JP7 or switch SW1,
the Keypad/Display can be removed by inserting a Phillips screwdriver into each of the
three holes located in the flexible covering of the Keypad/Display and loosening the
three mounting screws. Note that it is not necessary to disconnect the cables between
the Keypad/Display and the main circuit board unless the unit itself is being replaced.
Carefully lift the Keypad/Display and rest the unit at the bottom of the main circuit
board.
