If the Unable to Calibrate screen displays, then repeat the
calibration.
Note: Once the unit is calibrated, the calibration data
will remain saved in memory; the proper Symbol
Contrast and Modulation readings depend on
field calibration.
After three failed attempts to calibrate your unit, it is an
indication that your bar code verifier will need to be
Factory calibrated and serviced.
