(0L) is preferred for taking pictures of color documents, such as ID cards,
especially when the imager is in a stand. LED illumination (1L) is preferred
when the imager is hand held. LED State is not available when using

E - Exposure
Exposure is used in Manual Style only (2P), and allows you to set the
exposure time. This is similar to setting a shutter speed on a camera. The
exposure time determines how long the imager takes to record an image.
On a bright day, exposure times can be very short because plenty of light is
available to help record an image. At nighttime, exposure time can increase
dramatically due to the near absence of light. Units are 127 microseconds.
