i'm pretty sure it means the batteries aren't working for whatever
reason. if you've put fresh batteries in and it's still happening, the
battery wires might have come loose or something. i had one that did
this, and while it might be something very simple and obvious if you
open it, i couldn't figure out my problem at all. the wires were
obviously connected, and i couldn't see any problems in the circuit
paths. i just ended up backing everything up onto cassette and then
loading it back in before every show. it was actually quite reliable,
a lot less picky about levels than an mmt-8 with a similar problem. i
finally got a memory cartridge, which was a lot faster and less
nervewracking. you could use the cassette jack to back stuff up into a
computer audio recorder or minidisc too. there may be some type of
sysex, but i've never heard of it. my current machine doesn't have
this problem, but i mainly just improvise with it anyway.

good luck,
greg
