6 - 2 DS6878 Product Reference Guide
Scanning Sequence Examples
In most cases scanning one bar code sets the parameter value. For example, to disable image capture
illumination, scan the Disable Image Capture Illumination bar code under Image Capture Illumination on
page 6-5. The digital scanner issues a fast warble beep and the LED turns green, signifying a successful
parameter entry.
Other parameters require scanning several bar codes. See these parameter descriptions for this procedure.
Errors While Scanning
Unless otherwise specified, to correct an error during a scanning sequence, just re-scan the correct parameter.
Imaging Preferences Parameter Defaults
Table 6-1 lists the defaults for imaging preferences parameters. To change the default values, scan the
appropriate bar codes in this guide. These new values replace the standard default values in memory. To recall
the default parameter values, scan the Default Parameters on page 5-5.
NOTE See Appendix A, Standard Default Parameters for all user preferences, hosts, symbologies, and
miscellaneous default parameters.
