I just cajoled Santa into dropping off a BCD563HP yesterday and am fumbling around with the learning curve; loaded Sentinel on the PC and connected to the scanner. But I've not been able to find ANY sort of user guide on the features and how to use them, anywhere so far. I'm sure I can bumble around and figure out most of the basic stuff by trial and error, but surely there must be SOMETHING out there as a guide. The Help button is useless, as it just tells the version number. tnx de W2JC
