Disassembly and Replacement
4. Make sure the display is clean of all dust and finger prints. Also check
the back side of the display cover screen in the key pad to make sure it
is clean.
5. Orient the key pad and start the wire harness through the hole in the
cover assembly. Make sure the wire harness is straight with no twists.
DO NOT TOUCH THE KEY PAD TO THE COVER ASSEMBLY UNTIL
IT IS PROPERLY POSITIONED. IF THE ADHESIVE TOUCHES THE
COVER ASSEMBLY, IT WILL STICK IN THAT POSITION AND
CANNOT BE EASILY REPOSITIONED WITHOUT CAUSING THE
KEYPAD TO BE DAMAGED OR NOT ADHERE PROPERLY.
6. Carefully strip the cover paper off the adhesive on the back of the key
pad.
7. Carefully align the key pad to the depression in the cover assembly
without actually touching the key pad to the cover. Make sure the wire
harness is fully pushed through the hole in the cover.
8. Touch one edge to the cover and press the key pad down all across the
pad working toward the opposite edge to prevent trapping air under the
key pad.
9. Make sure the top of the cover screen is clean and free of dust and
finger prints.
10. Replace the main cover assembly (refer to "Section 9.1.3 - Cover
Assembly").
