Hi Folks, My wife is only using her Book Courier to listen to MP3 files. It seems to be working OK for this purpose but when trying to help her with a minor problem a couple of days ago, I pressed the help key and it started to play. No matter what key I pressed it wouldn't stop and I had to remove the batteries. I also noticed some time ago that the battery indicator always registers 50 per cent, even when new batteries are inserted. I don't want to fiddle with the machine at present, as my wife is reading a book but can anyone suggest how I may be able to correct these problems when she has finished? Best. Robert.
