3. With one hand over the PCA, roll the top case over (face up) and lift it away from the

PCA.

Note

Two red and one black plastic shields are used to isolate the user from the

input terminals. With the PCA removed, these shields are loose and can fall

away from the PCA.

4. Remove and set aside all three shields for use during reassembly.

XWWarning

To avoid risk of electrical shock, make sure the plastic input

terminals are properly positioned on the PCA before attaching it

to the top case.

To install the PCA, proceed as follows:

1. With the PCA face-up, place all three plastic shields into position on the PCA.

2. Lower the top cover onto the PCA, and roll both parts over (PCA up).

3. Connect (snap) the chrome plated springs to the INSULATION terminals.

4. Install the screw that attaches the PCA to the top case.

Removing the LCD

With the PCA removed, the final step in disassembling the Tester is to remove the LCD

assembly from the PCA. Refer to Figure 5 and use the following procedure to remove the

LCD assembly:

1. Remove the two screws from the display end of the PCA.

2. Hold the PCA face down with the fuse-end of the PCA toward you. Locate the

screw-hole near the center of the assembly. This hole is the one used to attach (with a

screw) the PCA to the top case.
