Outline of Full Auto Calibration Process (continued)
20. Take initial read rate at current settings.
21. Calibrate video, select new gain and tracking settings.
22. Take final read rate with new gain and tracking settings. (If the final read rate is < 2%,
video calibration fails; if final read rate is > or = the initial read rate, video calibration
passes and new settings take effect; if final read rate is < initial read rate, video settings
revert to pre-calibration values. This is not a considered a “failure”—all other settings
calibrated by other calibration processes (motor speed, laser power, etc) will still take effect.
23. Perform laser framing, (if enabled).
24. If symbology detection is enabled, update user NOVRAM with any new symbologies
detected during calibration.
Note: If any step in the calibration process fails, or the user cancels calibration, the
remainder of calibration is canceled, and all user settings are restored to their pre-calibration
state. This does not apply to symbology status when symbology detection is enabled.
Any symbologies that are decoded during calibration will be enabled, even if any other
calibration processes fail or are canceled.
