Hi Ed, The brf files from bookshare have worked quite well for me. Occasionally there can be some problems, but 99.9 percent of the time things are fine. You can turn off the beeps the Book Port emits when the unit is locked by going into the setup menu by hitting the zero. This toggles between setup mode and reading mode. I don't know if you have explored this much so you may already know all of this. You can look at the various options by pressing the number 2 or 8. There is an option for lock beep and if it is set to no then the unit won't beep when a key is pressed and the unit is locked. When you are exploring an option in the setup you can make changes by using the 4 and 6 keys. This is probably as clear as mud but it is 4 in the morning and I have not introduced my brain to caffeine yet today! Joni
