If the intensity function of Pin No. 6 is not used, set the
internal switch on the Qd board to the B position, and
connect the Pin No. 6 to the GND. With this setting, when the
positive intensity signal synchronized to the characters on
the screen is fed, the luminance of the characters will be
increased.
