Removing the PCA and Input Module

To avoid contaminating the pca with oil from your fingers,
handle the pca by its edges or wear gloves. A contaminated
pca may not cause immediate instrument failure in controlled
environments. Failures typically show up when contaminated
units are operated in humid areas.
After you have removed the case bottom, use the following procedure to remove the pca
and input module:
1. Before removing the board from the case top, disconnect the flex cable from the
board by pulling out the connector latch from the connector body. (Figure 3-2). The
latch remains attached to the connector body.
2. Pull the input module away from the case top. The input module remains attached to
the pca.
3. Lift the pca and input module out of the case top. The flex cable pulls away from the
connector when the pca is lifted out of the case.
