2.4.4 Calibration interface operation instructions
According to the market usage, the charger interface should be calibrated
regularly to solve the user's operating experience. In order to prevent the resistive
screen from being calibrated for a long time, the screen will shift as a whole. It is
recommended that the charger screen be calibrated once a month; frequent users
should reasonably shorten the calibration cycle, and it is recommended to have it
once every two weeks to ensure that customers have a good operating experience
(in the case of frequent and inappropriate use groups, users can Reduce the
calibration time as appropriate).
