C.2.3 Bar Code Decoding Camera Predefined Presets

The following presets enable successful bar code image capture in almost all conditions.

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 EP10.

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.

C.2.4 Image Capture Predefined Presets

The following presets enable successful image capture in almost all conditions.

Default

This preset works in a wide range of conditions. It is optimized for a normal office lighting (about 300 Lux).

Motion

This preset uses a shorter exposure time so as to freeze motion.

Note: It is recommended that the default preset be used whenever possible.
