Thanks all for the info. and advice. I have been messing with this unit for a week or so and have tried several adapters, as you know. Just this morning, for no apparent reason, it started working on a 2amp adapter, one which I had tried before with negative results. It has been running for about 1/2 hour or so. Gremlins at work here it seems, or maybe the CD device was stuck or something.
Again, thank you all for your input and interest in my minor problem!
