Hi, I have had two HR21s for about two weeks now. One is a HR21-100 and the other is a HR21-700. For some reason, my HR21-100 has been powering itself on about once a day. This is happening when I'm not around (note that I live alone so no one else would be turning it on) so I haven't a clue as to why it's doing it. Can some one help/explain what's going on? Is this normal (but if so, why doesn't my HR21-700 do it)? I sincerely apologize if this is FAQ, but I couldn't find anything about this.
