This function adjusts the scanning speed to facilitate scanning of hard-to-read symbols.
(1) Decoding deliberation levels
The level of deliberation with which symbols are scanned can be set at five different levels. Setting
the level to Very Quick or Quick limits the symbols which can be decoded but increases the
decoding speed. Alternatively, setting the level to Deliberate or Very Deliberate allows many
symbols to be read but slows down the decoding speed.
