OVERFLOW ERRORS
There are several
situations
which will cause an
overflow
or
en
error
condition.
When this
occurs.
EO. will be displayed.
The(];Jkey
must
be
used
to
reset
the
error
condition.
The following will
cause
an overflow
and
errors.
1.
The
absolute
value
of
a
calculation
result
is
greater
than
9.999999999

10"
or
smaller
than
1 x

.
2.
When a
number
is
divided
by
0 (zero. A

BEFORE
OPERATION
• In this
model,
the
keys
needed
in
each
mode
are
made
effective
for
the
operations
and
the
other
keys
are
electronically
locked
to
avoid mis-ealculations.
(As
for
the

and
the
mode,
see page

• Entries may
contain
a
maximum
of
10
