Adjusting procedure
» Adjust the PSIG waveform to the one shown below.
PSIG
2.5V DC
(Adjust with PSIG-H.)
» For the green and blue colors, make sure their wave-
forms are similar to that of the red color.
» 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 that scale (white side) to No.251 and
scale (black side) to No.8 can be seen.
» If white scale can't be seen properly, readjust with
G1-BLK.
