My problem with this recorder or any other voice recorder is that I couldn't remember how to perform some of the functions, and what buttons I am supposed to push to move files, etc. But there is now a video manual showing all the functions (broken into chapters) for Olympus 4100PC on www.HandBookLive.com under Electronics. I tried a similar Panasonic model but couldn't figure out the written manual, so I managed to password protect myself and not being able to reset it (ended up returning it back to Fry's). We made a HandBookLive video on Olympus 4100PC recorder so that others wouldn't struggle. Hope this helps!
