Antenna troubleshooting

The antenna is functioning normally when the spring contacts take proper contact to the antenna feeds.
Check that the spring contacts on the PWB and the antenna module are visually intact.
There are two antenna matching components (C7402 and C7413) on the PWB. Check that they are properly
soldered. In case of damage, replace the component.
