Hi Rick: If memory serves correct, you have 30 seconds to change your battery and have the settings preserved. So, if the batteries die and they're not changed in time ... As far as navigation, it all depends. Audible books aren't really marked up that much. You should be able to take advantage of the phrase navigation and maybe chapters in some instances. Try the 8 key, and 4 and 6 or 7 and 9.

Quite often, when I start my player, I find that the player has lost my last listen point and has, once again, started at the beginning of my selection. This anomaly also occurs sometimes after replacing batteries. As I mainly listen to Audible books on my player, this is very distressing. To compound the problem, no matter what I try, I can't advance the recording beyond a sentence or two. Is there a way of locking a bookmark in, so it can't be lost? Is there a setting that will allow me to advance an Audible book by larger segments? Thanks to all for your assistance in advance. Rick
