3.7.7.8 VCO Tuning
The VCO can be optionally tuned for each service/channel configuration during the RXMode
ramp-up. To enable VCO tuning for the selected service/channel configuration, set the
VCO_TUNE bit in the eepTrxConf.sysStartConfig EEPROM setting to start RXMode immediately
after power-on, or activate it in the systemModeConfig parameter when using a
Set System Mode SPI command.

VCO tuning requires additional time. For more information about the VCO tuning, see Tune and Check from Related Links.
