    I know there is a power outage. I don't need to hear about it for 3 days. They really need an alarm off switch. Instead, after an outrage, i have to remeber to plug this in. Or, for an inconsequential outage in the middle of the night, it wakes me up. You urban folks might not care, but im not in the most reliable spot.
