C.2.3 Bar Code Decoding Camera Predefined Presets
The following presets enable successful bar code image capture in almost all conditions.
Note: It is recommended that the default preset be used whenever possible.
Default
This preset works in a wide range of conditions. It is optimized for a normal office lighting
(about 300 Lux).

Low light

This preset is designed for very dark conditions such as inside a warehouse where the lights
are kept low, or inside an unlit truck. This preset increases either the exposure time or the
gain.
Low power
This preset minimizes the use of the flash so as to conserve the battery power on the hand-
held.
Glossy surface
This preset minimizes the use of the flash so as to reduce reflection. This preset is used to
read bar codes that are behind glass, or inside the plastic window of an envelope.
