7.
Press Shift + F4.
8.
Scroll down and select PROG CHARG-DAC DATA and enter the value calculated by subtracting the value recorded in
step 6 from the initial CHARG-DAC DATA value (442).
9.
Repeat steps 6 to 8 until the measured voltage is 4.2 V ±5 mV.
10. If the final value is outside the range 342 - 542, then there is a fault and further investigation is required. Otherwise, record
the value for use later.
11. Press F6. Highlight TRIM OTHER and press ENTER. Highlight DAC REFERENCE and press ENTER.
12. Enter the value recorded in step 10.

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 NAUSICA to measure charging
current as an amplified voltage across a sense resistor.
1.
Press F4 and select VIEW ADC LINES. Read ADIN5 (CRG CURRENT) and record this value.
NOTE:
This calibration procedure MUST be carried out once Charging Voltage calibration has been completed.
