I've been following the discussions re UPS. Always planned on getting one for the HT system - "someday."
Well gentlemen, last night I had the whole HT system turned on and the 515 was busy recording to the HDD while I was watching chase play. It was a beautiful night, no storm activity at all.
Suddenly, the room lights, which were on dimly, surged in brightness way past the normal max, surged again, after which I was left sitting in the dark - no power. To make matters worse, the lights surged on again THREE more times and then off, flickered wildly a couple times and then a two hour wait to see how much of the gear was going to have to be replaced.
We had had a major storm and power outage 4 days earlier, which had apparently caused weakness in a tree a couple miles from here. Came down and took out critical lines for the entire nearby community.
I've seen bad power failures with contiguous major spikes like this one in the past, but normally they've happened when they're turning the juice back on and I've already shut down the gear or the gear was off beforehand due to storm warnings. This one caught me flatfooted.
Long story short - no damage to the electronics. I'm overjoyed to report that the Maggie is one hell of a stable piece of gear! Yes, that's no excuse for me not having a UPS and that WILL be corrected. All the gear is plugged into a couple of those power strips that do have a minimum of protection, but I doubt it's what made the difference here.
I checked the 515 and it had merely stopped recording at the point the power failed. All stored titles were in place and the 515 began recording again on command. Even the clock did not lose a tick! I set the clock manually one time when I first got the unit and continue to use the manual setting, so it's not picking up the time signal from tv programming. It has never gained or lost a second. Amazing.
I know I was lucky and I won't stretch that luck any further.
Yet another testimonial from a satisfied customer!
