ADJUSTMENT
1. Flicker adjustment
Condition (same conditon as it is used in the
●
previous models)
Video Source: VIDEO
Video: Luster white 30%~50%
BRIGHT: MAX
MODE: ZOOM
Adjustment procedure
●
Display luster white 30%~50%.
q
Place a fl icker adjustment jig to the monitor and observe
w
the waveform with an oscilloscope.
Turn VR200 and adjust it to make the amplitude of the
e
waveform to minimum.
Oscilloscope range: 20mV, 0.5mS
Note
●
In checking the screen after the adjustment, shake the
q
monitor up and down in order to confi rm that the screen
does not fl icker. (This check is also carried out on the 07
model.)
Noise due to AC200V can be observed in the flicker
w
adjustment jig and oscilloscope, and thus carefully set up
the power supply and GND of the jig and oscilloscope.
* In the 07 model, GND of the measurement equipment
has been fl oated.

5. Touch panel adjustment
Adjustment procedure
●
Press the Touch key on the Test Mode Menu screen to
q
enter the Touch Panel Adjustment screen.
Touch the center of “+” mark below in the following order:
w
Upper left → Upper right → Lower left → Lower right
When touching the screen, make sure to use the
designated touch stick.
After adjustment is completed at 4 corners and if “Write
e
OK” is displayed, the adjustment is completed.
Press Return to exit from the Touch Adjustment screen.
Cancel Cancel
CancelCancel
* If the center of “+” mark wasn’t pressed accurately, press
Cancel to start over the adjustment.
Note
The touch panel adjustment data is fi nalized when the touch
stick is released from the mark.
Therefore, the knack for the adjustment is not to release
the touch stick away from the mark right after touching the
center of the “+” mark, but to vertically and quickly release
the stick away from the mark after confi rming that the stick is
exactly on the center of the “+” mark while keeping touching
the screen (if the stick is not exactly on the center, move the
stick onto the center while keeping touching the screen).
