Anyone got any knowledge / experience of this "Professional Twin SD MP3
player" *?

This one is from a customer who's lost his user guide. If you go to DJ
Tech's website, even though the unit is only a few years old, they list
it
as 'legacy' and only have a basic spec listed for download - no manuals.
Needless to say, they don't respond to requests for help in this regard.

The problem with the unit is that when you power it up, *( the soft
power
button works ok at this time), * the message * * "UpdateUI--"
appears
in
the left window. Anyone know what exactly it's trying to tell us, and
whether it's correctable with a master reset or something ? I'm guessing
that the "UI" bit might be User Interface ?? Beyond this initial
message,
it
does nothing, and doesn't respond to any controls, including the power
button. The only way to then get it to power back off, is to remove
power
from the wall wart.

Sometimes archive.org has legacy copies of older websites with the then
current user manuals

Thanks. I'll give it a look.

Nope. 'Fraid not. They haven't got that page archived.

Could it be that there is a noisy power line wreaking havoc with the
uPc? try another psu.

beyond that, it's schematics-and-scope time, or you're buggered...
