FMTx2.1 troubleshooting

General

The handset uses an antenna that is integrated to the B-cover. The connection to the half loop antenna is
exposed by disassembling the phone and removing the PWB.
The half loop antenna requires two connection points, signal C-clip (X6189) and ground (PWB opening in the
another end of the FMTX antenna). It is important to check these connection points for damage or dirt since
the performance of the FMTx 2.1 implementation will be severely impaired if these connections are not in
good condition.
