Some confusion between different models. My old type, fully hard case body. The New one, thicker, lower rubbery body.
After comparing documentations, here's what's important:
1. (I think) When bought new, do initial full discharge and recharge for 5 times. This is for full potential of battery life.
2. For date format:
2012.06.06 22.00.00
Y or N at the end of the line (with or without space before) is supposed to be for showing or hiding timestamp on video But it doesn't seem to work.
save the single timeline in txt file format and name the file: time.txt, to the root directory.
Keep pen charged or else time will reset to 1980 and this procedure must be repeated for correct timestamp.
