If any of the RF feed or ground pins are obstructed, removed, or covered, the RF pin does
not touch the PWB and the antenna performance degrades. If any of the IHF speaker
pads are obstructed, removed, or covered, the speaker's pogo pin does not touch the PWB
and the PCS antenna performance could degrade. See the
Pins" section for antenna performance degradation if any pogo pin does not touch the
PWB.
• If corrosion is present or the pad is missing, replace the mobile terminal.
• If a pad is obstructed or covered, clear and/or clean the pad.
