Scanning Sequence Examples
In most cases you need only scan one bar code to set a specific parameter.
For example, if you want to add Code 39 to the Wand parameters, simply
scan the Add Code 39 bar code in the Wand Code Types section. The LS 3603
will issue a warble tone, signifying a successful parameter entry.
If you want to add or change prefixes and suffixes you will have to scan several
bar codes. This procedure is described in Parameter Descriptions.
Errors While Scanning
Don't worry if you make an error during a scanning sequence. Merely reenter
the correct parameter.
