Have you checked the output of the charger adapter to make sure it has the correct voltage output? That would be my first suspect before the scanner itself (jack, batteries etc.).
hey did you ever get this figured out? mine is doing it as well it was just fine but I haven't had it plugged in for about a month and I plugged it in to charge it and that came up. I've had the batteries for almost 3 years could they be bad, and be causing this?
No, still havin the problem with it. It's not the batteries, cause, if I take the batteries out, and run it off of the charger only, it still won't work.
