2.8.7.9 RF Calibration
The temperature-dependent drift of the XTAL-based RF frequency can be optionally corrected for each service/channel configuration. To enable the RF calibration for the selected service/channel configuration, set the RF_CAL bit in the eepTrxConf.sysStartConfig EEPROM setting to start RXMode immediately after power-on, or activate it in the systemModeConfig parameter when using the “Set System Mode” SPI command.

RF calibration requires additional time. For more information, see Tune and Check.
