3.1. Setting of readable codes
These options do not affect the reading of the menu labels. The required bar code
types can be selected by enabling a single readable code only and enabling readable
codes.
It is strongly recommended to select only the required codes.
Advantages of selecting only the required codes are:

faster reading

no accidental scanning of unwanted bar codes

reduced probability of reading errors which cannot be prevented completely,
because of the limited security of some bar code types
Some bar codes are translations or special variants of other bar code types. The table
on the title page of this chapter visualizes these relations. The setting of different
codes is explained in the next chapter 3.1.1. Enabling a single read. code.
