Auto Enables decoder to auto discriminate supplementary codes (None, 2 or 5) on label①
① The Auto Selection allows you to mix labels without supplements with labels containing 2 or 5 digit
supplements. The supplements are often a different size than the primary symbol. Therefore, it is
critical that both the primary symbol and the supplement be present when the decoder is
triggered. If the decoder does not detect the supplement, the primary symbol is sufficient to
produce a valid scan. The Auto selection is not recommended when the Decode Mode is set to
Continuous.
If you select 2, 5, or 2 or 5, the decoder must decode both the
primary label and the supplement to produce a valid scan.
