READING FEATURES

3.2 DECODING CAPACITY IN LINEAR MODE

When in Linear Reading mode, the number of reads performed by the DS4600A and
therefore the decoding capacity, is influenced by the following parameters:

•

number of scans per second

•

code motion speed

•

label dimensions

•

scan direction with respect to code motion

At least 5 scans during the code passage should be allowed to ensure a successful
read.
