then press ENTER. The overall range of data rates is from 2.4 to 2048 kbps.
NOTE: The minimum and maximum data rates are dependent on modulation type and FEC
encoder rate. If the user changes the modulation or FEC, and the currently selected data rate is
then invalid, it will be adjusted automatically.
