  • How do you know the unit is off vs sleep mode? I’m always having to charge this when I go to use it after a week or so. Seems like a firmware upgrade to auto off after several hours w/o use would make sense?

  • Hi John, the device powers off without use after 6 hours now and after 2 hours with an upcoming firmware upgrade.  If you move the tape and the screen does not turn back on, the device is off vs in slep mode
