Removing RF Shields
Prior to installing an expansion card in expansion slots 3, 4, or 5, you must
remove the factory-installed RF shielding for these slots. This shielding
protects the rest of the ECN electronics from unintended emissions from the
wireless or cellular modems installed in these slots.
Figure 10 on page 22 shows these slots with and without their RF shielding.
