Switches
A.
Cleaning
The
exterior
of
the
game
cabinet
and
the
metal
and
glass
surfaces
may
be
cleaned
with
any
non-
abrasive
household
cleaner.
If
desired,
special
coin
machine
cleaners
that
leave
no
residue
can
be ob-
tained
from
your
distributor.
The
large
monitor
shield and
the
attraction
panel
are made
of
tempered
glass
and
should be
scratch-
resistant:
if
cleaned
without
abrasive
substances,
you
should
hardly
ever
have to
replace
them.
B.
Fuse
Replacement.
This game
contains
six fuses—
all on the
power
supply
assembly
(not
including the
monitor
fuses).
Replace fuses
only
with the
same type as
listed in
Figure
22 of this
manual. See
the
color monitor man-
ual for
the
monitor fuse
data.
C. The
Control
Panel
Prior to
repairing
or
replacing any
switch
or the
Mini-Trak
Ball™ on the
control
panel,
unplug
the
game.
Then open
the coin
door.
