Damaged IHF Speaker Spring Pins

In Figure 3, the two contact points on the back of the internal antenna must properly
touch the PWB. If not, no audio signal will emit from the speaker.

Obstructed Speaker, RF feed point, and Ground pads

If any of the RF feed point pad or ground pad is obstructed, removed, or covered,
the antenna pin does not touch the PWB and the antenna performance degrades. If
any of the speaker pads are obstructed, removed, or covered, the speaker's spring
pins does not touch the PWB and the cellular antenna performance could degrade.
If corrosion is present or the pad is missing, replace the PWB.
If a pad is obstructed or covered by something, clear and/or clean the
pad.
