MRECSET.txt. You see it when the pen is plugged into a computer, next to your recordings.
Most people only need to touch it once, to set the clock.
1
Plug the pen into a computer
Open it like a USB drive and find
MRECSET.txt.2
Open the file in a text editor
TextEdit on a Mac or Notepad on Windows works.
3
Change the line you need
Only change the value. Keep the same format that is already in the file.
4
Save, then unplug the pen safely
Eject the drive before you unplug it, so the change is saved.
The settings
A wrong clock doesn’t break anything. Juno still transcribes the recording. It may just show up with the wrong date, under Just added.
