Adjusting procedure
» Using the control switches or the remote controller
buttons, make sure that the "OUTPUT 3" charac-
ters are not blurry and there is no ghost image. If
such blur or ghost occurs, finely adjust the setting
in the range of 7~9.
» Using the control switches or the remote controller
buttons, adjust the data in order to minimize the
flicker.
» Make the same adjustment for BC (B) and GC (G).
» See if the image is equally adjusted at the center
and both sides of the screen. If not, readjust the
setting to have the image equal at right and left.
» Make sure the 251 (white) tone, shown below, ap-
pears noticeable. Be also sure that the 8 (black) tone
can be identified.
» If the white tone does not look as specified, finely
adjust the G1-BLK level.
