The carrier power must be measured and calibrated for each power level at channel 62. GSM 900 NOTE: To ensure that the telephone operates within set SAR margins, Panasonic recommends that a power meter capable of measurement to an accuracy of ±0.2 dB is used when calibrating power levels. Use of a less accurate power meter may result in the telephone failing to meet SAR standards. - Page 46 TEST AND MEASUREMENT At the power meter, measure the peak power. If measured power is in the range of the target power, then proceed to step 10. At the Channel box, press F7 to view the TRIM for the mid-channel.

Page 53: Battery Calibration
TEST AND MEASUREMENT 6.6.5. Battery Calibration Preliminaries There are three procedures to calibrating the battery, voltage, temperature and charging calibration. A Battery Calibration Voltage Control Unit (BCVCU) is used to provide the necessary voltage levels for these checks. The BCVCU replaces the two regulated power supplies and 82 Ohm resistor required to caibrate previous mobile products. - Page 54 TEST AND MEASUREMENT Figure 6.28: Battery calibration 2 Set VBAT to 3.0 V by selecting 3.0 V on the BCVCU. On the PC, press ‘Y’ and then ENTER. Check the ADIN1 reading again - this is the BAT VOLT LOW value. If the reading is outside the range 390 - 490, there is a fault and further investigation is required.
- Page 55 TEST AND MEASUREMENT Figure 6.30: Battery calibration 4 12. Set the BCVCU to 12 V. Temperature Calibration Ensure that VBAT is set to 4.1 V. Check that EXT PWR and IGN on the Interface Box is set to OFF. Scroll up the menu until CONTROL OUT is highlighted. Using the left / right cursor keys, highlight AADC ON and then press ENTER.
- Page 56 TEST AND MEASUREMENT Figure 6.32: Temperature calibration 2 Charging Calibration On the Interface Box, ensure that the EXT PWR switch is ON. Check that the BCVCU 82 Ohms switch is set to ON. Holding down the Shift key, press F4. Select PROG CHARG-DAC DATA. Figure 6.33: Charging calibration 1 Enter a value of 439.
- Page 57 TEST AND MEASUREMENT Figure 6.34: Charging Calibration 2 Disconnect VBAT by setting the BCVCU Voltage switch to OFF. Measure the voltage across the Test Battery terminals. If the voltage is within the range 4.2 V ±5 mV, proceed to step 11. Otherwise, calculate the difference (DAC STEP) as follows: difference = (measured voltage - 4.2 V) / 7.4 mV Press Shift + F4.
- Page 58 TEST AND MEASUREMENT Figure 6.36: Charging calibration 4 Current Charging ADC Calibration It is important to monitor the current when charging the Li-ion battery, both to protect against over-current and to determine when charging is complete. The telephone uses the VCC3 and MADC (ICHG) connections of OMEGA to measure charging current as an amplified voltage across a sense resistor.
