Hello again Further to my earlier posts, I think the problem I have is with the enter key. I am unable to do anything other than start and stop play with the enter key. For example, I can't set a bookmark, I press the bookmark key twice and it prompts me to enter bookmark. I enter a number and press the enter key. This results in the same sound as with the heading key and does not create a bookmark at all. Similarly, if I go into editing items through the menus, if I choose to save and it prompts me "are you sure", then if I press enter to confirm, then the ending sound and nothing happens. I am taken out of the menus and back in the file. It looks to me as if there is a dodgy connection with the enter key. I bought the unit from the RNIB a number of years ago, do they process units for maintenance, or will I have to send it directly to the makers? Many thanks once again. Regards ... Scott
