Setting the Dim Level
The display will dim when the ambient light is low. This
adjustment sets the dim display level. It has no effect on the bright
display level. The dim level may be set from very low—0—to
bright—31. Hold a doubled over piece of black electrical tape (or a
similar opaque strip) over the photo sensor that is on the left side of
the display to dim the display (450 single only)
