Minimum point of the resistor is the minimum luminance. Also maximum point of the
resistor is the maximum luminance.
between BRTI-BRTH terminals. This control method can carry out continuation
adjustment of luminance.
The variable resistor (R) for luminance control should be 10kΩ ±5%, B curve, 1/10W.
The resistor (R) must be connected between BRTH-BRTI terminals.
Voltage control method works, when BRTH terminal is 0V and VBI voltage is input
Luminance is maximum when BRTI terminal is Open.
