I don't know if this will help you, but here's a link to an owner's manual online for the WOW system. Down towards the bottom of the last page, there is a reference to what looks like a green light that states that rapid blinking may indicate that all the WOW remotes have been erased. There is also information on programming remotes.

Incidentally, WOW also means Wireless on Wheels.
