This will probably work for most Orion V-Chips... I figured it out looking at another manufacturer's instructions, on my Orion it was:
  *  Turn the volume down to 0
  *  Change to a blocked channel (where it asks for V-Chip password)
  *  On the TV (not from the remote) hold the volume down button
  *  (While holding volume on TV) hold the '0' key on the remote for between 2-10 seconds... 
  *  The screen should unlock, and you should have no V-Chip restrictions. 
You can now use your manual to find out how to set the restrictions you want.
