Battery Calibration9.4.1 PreliminariesThere are two procedures associated with battery calibration, battery temperature and battery voltage.1. Connect the RF Adaptor / Baseband Jig, telephone and PC as shown in the diagram below.Figure 9.3: Battery calibration test connections2. Set the Interface box to POWER ON, IGN and EXT PWR OFF.3. With the CB2000 software running, select the ‘Baseband Calibration’ button.4. Select the Battery Calibration tab.5.
