FMTx 2.0 schematic

The handset uses an antenna that is integral to the removable cover. The connection to the cover is exposed
when the cover is removed. The ESD diode package (Z2600) and the resistor (R7825) are fitted to protect
against ESD strikes.
The loop antenna requires two connection points (the signal and the ground). It is important to check these
connection points for damage or dirt since the performance of the FMTx 2.x implementation will be severely
impaired if these connections are not in good condition.
