If the image is not correctly centered
If the picture from a new source computer does not seem
correctly centered, the input position memory presets might
require resetting. Reset the input position memories as follows:

Unplug the interface’s AC power cord.
2.
Hold down the input selector switch while you plug in the
interface’s AC power cord and wait approximately 5
seconds.

To test the system setup and output, substitute a video test
generator for one of the computer inputs. Use the VTG
that is built into the RGB 203 R
xi
VTG, or use a stand-
alone VTG with the RGB 203 R
xi
. To use a stand-alone
VTG, unplug the input and output devices’ and the
interface’s power cords, replace the video source with a
VTG, then reconnect power cords to restore AC power.
