USING
THE
MAPS
When using the MAPs, you must:
READ
CAREFULLY. The MAPs can help you find the
problem only
if
you
follow
instructions and answer
questions accurately.
FOLLOW THE SEQUENCE. Always proceed step
by
step.
At
times, the MAP instructions might seem
irrelevant; however, they can
be
important in
determining the correct error indications.
FOLLOW INSTRUCTIONS. Instructions must
be
carried out exactly in the order given.
Each
question
is based on instructions immediately preceeding it. Do
not change the conditions established by the
instructions before answering the questions. Do
not
press RESTART until you are told
to
do so
in
the
MAPs.
When you are asked
to
probe a line in the MAPs, the
line name and its active level are given. For example:
-Probe F2-G06
(-
machine check).
The - (minus) in
front
of
machine check indicates that
this line is active at a
down
level.
