Decode Customize Function
This function adjusts the scanning speed to facilitate scanning of hard-to-read symbols.
• Decode Deliberation Levels
The level of deliberation for scanning symbols can be set at five different levels. Setting the level
to “Very Quick” or “Quick” limits symbols which can be decoded, but increases the decoding
speed. Alternatively, setting the level to “Deliberate” or “Very Deliberate” allows many symbols
to be scanned but slows down the decoding speed.
