Calibration item using the direction
keys and press <Enter>.
Highlight Yes in the Battery Calibration
Confirmation window and press
The Battery Calibration function is activated and the battery is forcefully discharged. To stop the operation, press the (Esc) button.
This operation requires 3~5 hours depending on the battery capacity and the remaining battery charge.
