The Model
5200
tests
are run using the Port Board (Loop
Back
Board) which
automatically cycles through all of
the
tests. If
a
test fails: turn the unit off, remove
the Poit Board,
plug
a
game controller into Port 1, and turn
the
unit back on. You
can
select any of the tests manually
by
pressing the proper key followed
by
the start key.
NOTE:
The
Diagnostic
Cartridge
will
cycle
automatically
only
if
the
Port
Board
is
inserted before the
unit
is
turned
on.
Press the
*
or
ill
key followed
by
the start key to print this menu on the screen.
