Note. The values of the table 2 “LED drive current settings” are not guaranteed. The actual current values will spread around the values in the table. Espe-

cially the variation in 0.8mA setting is wide, and some of actual current may become 0mA. We recommend the usage that the minimum LED driving

current value is set at 1.6mA at the brightness adjustment.
