10.6 Overview of RF Calibration
10.6.1 Supported entry of RF Calibration
As using QTR8200, E730 adopts some of calibrations in those of QTR8200. This is also supporting Quad band
WCDMA and Quad band GSM. Table 10.6.1 and Table 10.6.2 describes the information listed for RF
calibration items used by E730.
