Note: Table 12 If the Bit value does not fall within the specification, please check if the lens of the camera is clean, if the lighting condition is good, or if the connector is connected properly.Note:As the maximum value of the Bit value is the warning value for the upper limit, the adjustment can be performed even when the value exceeds the specification.If the Bit value exceeds 448 (the seven eighth of the maximum value), it may attribute to the deterioration of the lighting device. It is recommended to replace the lighting.(The maximum value of the Bit value: 512)
