The
repeating
test proceeds automatically.
(If
the
test
doesn't
proceed, you
probably
pressed
ION
ICY)
by
mistake. This starts a
different
test,
used
at
the
factory,
that
requires
input
from
the
keyboard.
Quit
this self-test
by
executing a System Halt,
de-
scribed in step 4 below,
and
then
start
the
correct
repeating
test.)
3.
Watch for
the
test message.
The
test
shows
horizontal
and
verti-
cal lines, a
blank
display, a
random
pattern,
and
then
it displays
the
result
of
the
test.
•
The
message
01(-2:3S
indicates
that
the
calculator
passed
the
test.
• A message
such
as 1
FA
I L indicates
that
the
calculator failed
the
test.
The
number
indicates
the
nature
of
the
failure.
When
you
send
the
calculator for service, include
the
failure
number
and
printed
output
(if available).
If
you
interrupt
the
repeating
test
by
pressing a key,
the
test
returns
a failure message because it
didn't
expect
any
key-
strokes.
Such
a
failure
message
doesn't indicate a
problem
with
the
calculator.

the
test
by
performing
a System Halt.
a.
Press
and
hold
I
ON

If
