Power Supply
The RGB 300 is equipped with an internal auto-switching
power supply that operates from any input voltage in the 90 to
270 VAC, 50/60 Hz range. No equipment changes are
necessary. The fuse should only be a 250V 0.5A Slo-Blo type.

If no video input was detected, no memory block was
loaded, and the display will show spaces.
The scan rate menu may be used for troubleshooting as
follows:
The timing for the RGB 300 is derived from the vertical sync
signal. If the vertical sync signal is not present, both
the vertical and horizontal frequencies will be zeros,
even if there is a horizontal signal present.
If a vertical sync signal is detected, and the horizontal
sync is not detected, the vertical frequency is
displayed, but the horizontal frequency is zeros.
2. Recheck the Basic Installation steps for correct cable
connections, etc.
3. Fourteen memory blocks have been loaded with preset
video formats to match most computers. Check the following
memory preset table to see if the format specifications
match those required by the computer video signal.
