3. Scan the 2 digit hex value from the Numeric Bar Codes
4. Scan the output format to enable or cancel hide char function.
Custom prefix and suffix
Maximum 20 prefixes and 20 suffixes can be added to scan data for use in data editing. To
set these values, scan a double-digit hexadecimal number (i.e. two bar codes) that
corresponds to ASCII values. See the Table 1 and Numeric Bar Codes in appendix.
