Installing the Display
Refer to the illustration.

1. Form a 45-degree bend in the end of the display cable.
a. With needle nose pliers, clamp the flex cable just behind the exposed flex circuit
trace. You will form the bend along the edge of the pliers.
b. Press the end of the flex cable against a hard surface to bend it 45 degrees,
toward the display side, at the edge (bend line) of the exposed flex trace.
2. Peel the protective plastic liner from the front of the display.
Note
The first two steps of this section apply only if you are installing a new display. If
you are reusing a display, skip to
step 3 on page 54 .
Caution The display flex cable is fragile. Damage may result if the flex cable is
bent too sharply or if its connection with the circuit board is stressed.
Caution The direction of the bend is towards the exposed flex circuit trace. Do
not bend the cable in the opposite direction.
Note Remove the protective liner before installing the display in the case.
