I just got my Olympus 8100PC late yesterday and I'm already able to record and playback! Considering I'm not the most technology savvy person going, I was able to set the time. For anyone who is having trouble reading the instructions (they are NOT what I'd rate 5 stars!) this is how I started off:
Setting Time and Date
Push the OK/Menu button in the center of recorder and hold for a few seconds. (It will bring up a menu). Using the minus key, scroll down to "Device Menu" (it's all the way to the bottom and there may not be enough room for it to show up until you scroll all the way down to it). Highlight it, and push the OK/Menu button.
Select "Time and Date" and push the OK/Menu button again. Using the directional arrows on the sides of the OK/Menu button, set the date and time. When you have finished, push the OK/Menu button, then push the "STOP" key. It's all set!!
Once you have gone through this process, you will find the others less confusing! I hope this helps someone!
