a
reset
of
TC
2290
will
take
place

The
error
#

indicates
that
a
reset
has
occurred
which
means
that
you
have
lost
all
your
presets
and
special
no
settings.
—
They
have
been
overwritten
by
the
factory
default
values.
(If
you
have
written
‘1’
in
the
spec.no
37
only
the
factory
presets
are
restored).
To

On the next power up the error 13 will disappear.
If
the
ERROR
13
does
not
disappear
or
reappears
on
later
power-ups
there
might
be
a
fault
in
the
back-up
circuitry
—
in
which
case
you
should
turn
in
your
TC
2290
in
for
service.
Error + 20 is Shown Occationally
Each time the TC 2290 is powered up it does a self check rutine. If any faults are found they will
be shown as an error no in the delaytime display.
The rutine includes a check of the software PROM and the preset RAM contents.
lf any such ‘hardware’ fault errors occur they are shown as error + 20. Further diagnose of the
fault can be done by reading the contents of spec. 24 which normally reads ’0’, but takes a non-
zero value when an error has been found. If it shows ’3’ the PROM has malfunctioned.
Although an error 20 has occurred you can continue using the TC 2290 (at your own risk), you
can also stop the warning message '20’ by writing ’0’ to the spec. + 24., however if it reappears
we strongly advice you to send your TC 2290 in for service.
