Yeah, that means it shut down for low voltage, then tried to start up again. That cycling is bad for your stuff, and is one reason I bought one of those Hughes "gadgets/voltage booster" that swaps amperage for voltage. It's a voltage "booster" that kicks in when things get below the standard 110-120 range. It actually works great, and I can tell my AC unit loves it. It starts and spins happier.

I t has been plugged in 24/7 since last December, this is the first time I notice it, not sure when it happened, but other than the batteries, nothing else is on. We did lose our power last month during a storm, possible from that. I'll reset it tomorrow and watch for it again.
