Dear friend,Thanks for your inquiry.No, it doesn't. The device cannot save the set frequency if the item is out of power.Thanks a lot.

Hi. I don't think so. But then again I always turn it off by habit as soon as I am done, I unplug it. But if you check the description of the product it should tell you if it has that feature. In any case, it was a great price and a great buy for me, I am still using it and loving it. :)

I'm not sure...I don't leave it on when it's not in use. I only turn it on when I go to back up my files and then I power down after I'm done/eject.

if your device is off, the adapter will turn off. so it will not use connection when not being used.

It is a plug-in with a battery back-up. So it keeps your settings if you have to unplug. It is working well for us. It has an alarm that can be set to ring for a duration of 2 min. or 30 min. We have it set to go off twice a day.

Yes. Set it to the off setting. No nite lite but full function in case of power loss.

Yes, once the unit has been plugged in and charged, it has a back-up battery that will preserve time and settings during intermittent power outages.

The settings are stored in non-volatile memory. In other words, long term memory like a flash drive. I've had it unplugged for several months and it retains the set points.

No. I love it but wonder if it will drain my battery if I forget to unplug :(

Yes but it won't last long if you need to unplug it and plug it in regularly

yes - that is its purpose. anything that you can turn off and then on again by unplugging and then replugging in will work. The only caveat is devices that go into "standby" mode, like an audio amplifier, that need a second signal to go from standby to on.

Yes it apparently does. I know once the source device disconnects, after a while it will have to be powered up again to use.

Yes, it does. It appears to hold the high/low setting also. I have turned it off and back on and also had a blip with the electricity and the frequency stays to what I have set.

Yes,All settings can be saved automatically. Setting contents would not lost when power supply drop.

I use it primarily unplugged unless I am on for extended periods of time. Occasionally I have had too much data combined with long periods of use that require I plug it in because it gets so hot.

If unplug you need to reset it .. If turned off when you turn it back on it stays at old setting

YES. I have unplugged the base unit several times as I put my new office desk in order. The backup power from the handset is limited by the rather small AAA batteries, so I don't expect it to last very long. In my experience, the majority of power outages or brown-outs are very brief (i.e. less than 2-3 seconds) and anything longer is probably going to be hours, not minutes. I think this is a thoughtful feature and it's showing up in more and more ordinary devices that aren't much fun to re-program. It works unless the handset isn't in place during the outage, but even then, I didn't lose any programming (addressbook, speed dialing, and cell phone pairing). YES.
