3. Place the display board in the bezel assembly with the flex cable at the bottom next to the data
card slot. Ensure that the five smart key buttons and keypad are in place. Fasten the display
board in place using four standoffs (252-0209).
Torque the standoffs to 4.2 lb.-in.
Caution: Do not exceed 4.2 lb.-in of torque.
4. Carefully plug the display controller board into the connector below on the display board. Ensure
that the photocell fits into the hole in the bezel when positioning the display controller board.
5. Fasten the display controller board in place with five screws (221-0212).
Torque the screws to
2.4 lb.-in.
6. Replace the three knobs on the rotary switch shafts. Apply Loctite (664-0042) to the setscrews.
Tighten the setscrews using the 0.050" hex driver. Space the knobs 0.010" off the bezel so they
will turn smoothly. Space the outer knob from the large knob slightly so that it will turn freely while
keeping the bottom of the small knob inside the cavity of the large knob.
7. Insert the flex cable (with the exposed contacts facing away from the rotary switches) into the zif
socket and snap the collar on the zif socket into place.
8. Tape the flex cable together just above the zif socket to prevent it being trapped inside the data
card rail during installation.
9. Put the bezel assembly on the chassis. Ensure that the flex strip does not get trapped inside the
data card reader slot (see Bezel Assembly Replacement procedure).
10. Test the unit to verify proper operation (see Return to Service procedures).
11. Using the Service Data Sheet, reenter the customer configuration.
