Service hints:
To solve autoreverse problems at start
production, temporarily a small extended
printed board (PU03) has been added.
Together with this board microprocessor
QU01 with first version software has to be
used. Sets equipped in this way have been
marked MZOO.
Later on the software of QU01 has been
modified and the extended board is deleted.
Sets produced in this way are marked
MZ01, lotnumber 04 and higher.
In case the microprocessor QU01 of a set
marked MZO00O should be replaced, use the
modified microprocessor stamped
(HU024DNO3F) and remove the extended
small printed board (PU03) and reconnect
the cut copper pattern on the bottom side of
the main PC board, between QU01 pin 61
and connector JU01 pin 10, with a wire.
(See figure on next page). The modified uP
QU01 is available with:
4822 209 90104.
