A Weight Guard calibration error code is generated when the system degradation is severe. These codes indicate to the user to examine the system/clean the platter. Re-calibration can be performed if the error persists after system cleaning.
The scanner will not display a calibration error with a third-party scale installed.
The system LED also blinks red to indicate the severity of the condition. The following warning codes are generated on the 7-segment display depending on which Weight Guard shows the error condition. The off-platter detection feature is disabled while in this state.
