Tried to use my Dane-Elec digital pen a little while ago but the receiver did not acknowledge any pen activity. I suspected the 2 little on-board batteries were dead. Used it a lot in Jan and Feb last year...Did volt tests:
battery one: 0.60
battery two: 0.22
Should be 1.5 VDC. So, need to find some new tiny GP393 cells.
