•
For software updates which you carry out
yourself, you need to find the relevant
EPROM on the main circuit-board (the one
with the MIDI / SYNC connections) and
exchange it with the new software EPROM.
•
Before removing the old EPROM make sure
to take a note of which end has a notch in it.
The new EPROM must be inserted the same
way round. Usually, the notch is also marked
on the socket – but make sure anyway.
•
To remove an EPROM to make the
exchange, we recommend ideally using a
specialised IC tool, or if that isn‘t available,
levering gently with two small screwdrivers,
one at each end of the EPROM. Of course, if
you can only find one screwdriver, lever each
end in turn very gradually. Too much force,
or too much haste, and you could either
damage the casing on the IC, or bend one or
more of the pins.
•
On the new EPROM, check that the legs are
all at the correct angle in relation to each
other and the IC casing. As long as they are,
the EPROM will be easy to insert into its
socket without any undue effort, and you‘ll
avoid the possibility of bending or snapping
one of the legs, or even, at worst, damaging
the IC socket.
•
Before re-assembling the case, check again
very carefully that
−
the EPROM is inserted the right way round (if
not, it‘ll certainly be destroyed as soon you
switch the
REGELWERK back on)
−
no plug or connector has been loosened or
totally disconnected.
•
Now you are going to be able to use the
REGELWERK again
⇒
but only after re-assembling and re-fixing the
case.
