Question about voltage limiter

I bought an RTE IVR 3 for my 69 barracuda. I'm actually working under the dash now. I tried to contact them with an email and phone call.

Here is my question. The red led light keeps flashing...............I selected not to reinstall the factory condenser. Anyone else seen that with the RTE limiter?? Again. red LED light keeps flashing after about 5 minutes when the car is running.
I don't know what their flashing LEDs mean. I know you should probably start a separate thread since yours is a very different animal from what this thread is about. Hell I'll ask anyway...
How did you approach/resolve the original limiter issue?
