Has anyone experienced intermittent problems with the H2 recorder. The first problem I noticed was that it would stop working during a recording. I use it pugged in usually and when I check out the device it says, "PLease Power down". Or something like that. And the instructions are not clear on the display. Theres a line going through it too. Some times it works fine and no problems but its becoming a pain. Its only about 2 or 3 years old.
