The m100 and t102 have an internal nicad which must be on and charged. Turn the memory power switch on the bottom on, and leave the units plugged in for a while. Maybe overnight.
There's also a contrast knob on the side that may need adjusting. This along with a "cold start" almost always works. -- John On Mon, Mar 13, 2017 at 10:10 AM Gregory McGill <[email protected]> wrote: > I just picked up one of each, they were working before shipping to me > (seller showed me pictures) but when I try batteries and DC power > wallwart(from my other working 100) neither do anything. > > > Is there a good flowchart/troubleshooting guide? > > Greg >
