Data Overwrite Procedure - Panasonic EB-VS3 Service Manual

1. Connect power supply PS-2 (Bipolar) so that it supplies 3.6 V to VBAT.
2. Change PS-1 so that it is set 4.2 V with a current limit of 800 mA.
3. Monitor the current . ADC value in the ADC Meas. Box.
If this average value is outside the range of 3524 to 3970, then the unit has field.
4. Enter the average current. ADC value into the LOAD Excel sheet in the current = 800 mA field.
5. Change PS-1 so that it is current limited to 200 mA.
6. Monitor the current.LOAD ADC value in the ADC Meas. Box.
If this average value is outside the range of 2413 to 2538, then the unit has failed.
7. Enter the average LOAD ADC value into the LOAD Excel sheet in the current =200 mA field.
I = 0.8 (A)

OK
8. Convert the Excel sheet of EEP data to TXT (text) format.
9. File ---> Save As ---> Text (Tab delimited) ---> Save
10. Rename the epp file from the original filename and then save to PC.

9.4. Data Overwrite Procedure

1. From the "Modes" pull-down menu, select "EEPROM".
2. Click "Read EEPROM" value from the phone. The "eep-static" folder is opened.
3. Click "Load Eeprom Text File".
