If the intensity function of Pin No. 6 is not used, set the
internal switch on the Qd board to the El 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.

board to the A position, and feed the intensity control signal
to Pin No.6.
