L - LED State
Determines if the LEDs should be On or Off, and when. Ambient illumination (0L) is
preferred for taking pictures of color documents, such as ID cards. LED
illumination (1L) is preferred when the scanner is handheld. LED State is not
available when using Decoding Style (0P).

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 scanner 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.
