Decoding Preferences

The parameters in this chapter control bar code decoding characteristics.

Focus Mode

Select the Focus Mode to control the working range of the digital scanner:
• Select Far Focus to optimize the digital scanner to read at its far position. Use this mode when scanning large bar codes in
order to fit these bar codes in the digital scanner's field of view.
• Select Near Focus to optimize the digital scanner to read at its near position. Use this mode when scanning small, high-
density bar codes.
• Smart Focus toggles the focus position after every frame. This mode is ideal for scanning a combination of small and large
bar codes. Note that this mode can result in a slight loss of scanning aggressiveness as the digital scanner toggles between
near and far focus.
