Using the auto tune panel
The Auto Tune panel should only be used if one or more of the following components have been changed:
• The Si4713 device.
• The Inductor connected to the TXO pin 4.
• The inline resistor connected to the TXO pin 4 (if fitted).
• The ESD diode package connected to the TXO pin 4 (if fitted).
This procedure follows the alignment that is done in the factory to ensure that the FMTx 2.1 solution is aligned
to provide the correct Tx output power for the relevant legislations such as FCC and ETSI.
