Solution/Action:
Check that the shield is securely attached to the cooling fan. Replace it if it is loose or
missing. Do not re-use loose shields. Re-calibration of the test set is not required.

It will be necessary to remove one or more RF assemblies to
access and/or inspect the state of the shield. Insure that the RF
assemblies are re-inserted correctly into their respective motherboard slots.
