8. CONNECTION TO SETTING AND DISPLAY UNIT
Fine adjustment of the video signal is supported to enable its use with
stand–alone type PDP. This adjustment is necessary to compensate for
errors resulting from the combination of CNCs and cables.
Adjustment of the video signal is necessary if you have replaced the
display unit, cable, or a hardware component of the display circuit in the
CNC, either as part of regular field maintenance or to correct a failure.

D Stand–alone type PDP : Switch SW1
1 Change the jumper pin or switch setting such that flicker is eliminated.
2 If you find that flicker is eliminated by two or more different settings,
select the setting approximating to the midpoint of those settings.
Example : If flicker is eliminated by all of settings 2 to 6, select 4.
D Stand–alone type PDP : Switch SW2
1 The screen can be shifted horizontally in units of dots.
2 Adjust the horizontal position such that the entire screen is visible.
Only one setting can successfully realize this positioning.
Do not attempt to change any controls or settings other than
those described above.
If a PDP is used with two CNCs by selecting one at a time,
the adjustment described above must be made each time
switching between the CNCs occurs. So, this configuration
should be avoided.
