Texp (max) and LS (max) are represented in the graph below as the curved line for X (code
resolution). Values above the curve result in blurring. In practice, the application values are
somewhere below the theoretical line, (in the green area), due to environmental and other
conditions.

For example, the maximum target speed in the application is also affected by these
conditions:
Code/Background Contrast: maximum speed decreases when decreasing image
contrast (poor quality codes, reflective transparent coverings, different supports and
printing techniques).
Code Resolution: maximum speed increases when decreasing code resolution, (i.e. 2X).
There is a decrement of overlapping effects between two adjacent elements.
Tilt Angle: maximum speed decreases when increasing Tilt angle (from 0 to 45
degrees).
The Internal Lighting Mode parameter allows setting the operating mode of the internal
lighting system. The possible values are:
Disabled: the built-in LED array is turned off all the time. This option can be useful if using
an external lighting system;
Always ON: the built-in LED array is turned on all the time at the lowest power level. This
option is useful if the LED-array blinking (Strobed operating mode) disturbs the operator.
Very High/High/Medium/Low-Power Strobed: the built-in LED array is on only during the
image exposure time. Four different lighting levels can be set.
NOTE
To avoid LED array overheating, for Power Strobed settings, the program
automatically limits the range of allowed values for the Exposure Time
parameter. Therefore, after changes to Internal Lighting Mode, recheck
Exposure Time.
