Video to VGA Converter/Switch

5. Troubleshooting
If your monitor goes blank periodically …
Some VCR's (particularly lower cost ones with no time-base
correction), output jittery and unstable video signal timing (especially
in FF or PAUSE modes); however, the AC135A-R2 performs the
conversion to VGA regardless. Some VGA monitors or LCD's may not
be able to handle the instability in refresh rate and may lose the image
lock periodically. If this occurs, the solution is to: use a different VCR
with time base correction (TBC), change the monitor to a different
brand/model, or use a time-base corrector (or sync stabilizer).
If you want to substitute power supplies …
The universal power supply that comes with the AC135A-R2 generates
6v DC output. Do not apply a DC voltage higher thatn 7.5 V to the unit.
