As it arrives from the factory, the SL40 automatically adjusts its display brightness for the current lighting conditions. A small sensor at the upper left of the display is used for this function. There are two adjustments available for controlling the brightness level of the display. The first controls the lower brightness level in the automatic adjustment range (Lo Dsp Lvl). This is the brightness used when in total darkness. The second adjusts the upper limit of this range (Hi Dsp Lvl). This is used when bright light is shining on the display.
The factory settings for these are at the limits of the range, 0 (Lo Dsp Lvl) and 50 (Hi Dsp Lvl). The range can be reduced if desired using the inner knob to adjust the two values.
Some users may wish to disable the automatic dimming function. This can be accomplished by setting the high display level to zero. Now the low level adjustment will set the brightness of the display directly with no automatic adjustment made based on ambient light.
