Symbol Type
When set to Calibrate, all supported symbologies (except PDF417 and Pharmacode) will be attempted during calibration. Symbol lengths are not detected. Any new symbologies successfully decoded during calibration will remain enabled at the end of the process. All enabled symbologies will remain enabled.
For example, assume that only Code 39 is enabled at the beginning of calibration. If a Code 128 symbol is read during calibration, then Code 128 as well as Code 39 will be enabled at the end of calibration.
