You need to locate the cause of your power problem and fix it.
Do you have a UPS? What happens if you connect the DNS-323 to it?
Do you have a loose connection somewhere?
Do you have frequent power outages?
Do you have a digital clock or any other device with a digital clock that you could connect to the same outlet?
Many years ago I was staying in a suburb of Miami that had significant construction going on, new roads being built, new housing developments, etc. and we had outages on a daily basis, even though I never once saw the power off, I would wlak through the door and have to reset the clocks on the stove, microwave, VCR, etc., etc.,
