Setting LCD Contrast/Brightness

To adjust the LCD screen contrast:

• V230 / V260
  To adjust the screen contrast, locate the LCD contrast control on the top of the controller. Using a flat-bladed screwdriver, turn the control in either direction; the screen contrast changes.

• V120 / V280 / V290
  Store values into SI 7, LCD Contrast Control.
  0=Minimal Contrast, 50=Medium Contrast, 100=Maximal Contrast

To adjust the screen brightness, store values into SI 9 as follows:

• V120 / V130 / V280 / V290
  Screen Brightness.
  Note that 0=Off, 1=- On (low intensity) (V230 only), 2 - On (max. intensity) - Default

• V350 / ERROR: Variable (V570V1040V1210) is undefined. – 0 to 100, where 0=off, 40=40% brightness, 100=100% brightness

Note that this is relevant for CSTN displays only.
