Just bought an 1100S. Right out of the box I couldn't get it to turn on - the power button would toggle the red LED on the bottom of the unit off and on, but no signs of life. Unplugged the power from the back and plugged it in again and it was fine.
Switched it off, went out, decided to test the remote recording. Came back to the same power-up problem, and again had to unplug it and plug it back in again. The recording hadn't happened.
I just tried plugging in an ethernet cable instead of using wifi in case that was a problem, and another thing I did was turn off the power saving (but still put it in standby). The impression I got from the description was that if power saving is on it can take up to half an hour to register a remote record, implying that if power saving is off then it'll be pretty much instant. But no, the test recording I just tried took 20 minutes to happen - it did eventually though. The phone app also tends to be "out of sync" with what's recorded on the box.
It's the power-on problem that concerns me the most. Do you think I need to get it exchanged?
