from it's holster. Install new coin
mech putting the ribbon cable
back through the hole in the side
of the coin mech bracket, to the
bill verifiers P27 plug . Before
plugging in the header plug, you
will note that the header plug
from the new coin acceptor has
no keys, therefore, preventative

P27. Now reinstall the old coin
funnel above the new coin mech.
STEP
Two: Remove the side
panel of the bill verifier that is
mounted on the door. The side
that will be removed is the one
that is closer to the edge of the
door. There are four Phillips head
screws that hold this panel down.
Behind this panel is the main
CCU board that controls the ac-
ceptor and has the calibration
pots mounted on it. Now that this
panel is removed, the main
PROM is the next item to be re-
placed. You will find the PROM
in the kit that is marked CSS-001.
See figure 2 for PROM location.
STEP THREE: Turn on the C-500
unit and clear all errors. Type
"500" on the key pad. (See fig-
ure 3 for key pad view) "TY-XX"
should appear in the display. If
two quarter hoppers are present,
program the unit in this manner.
Be sure that "dispensing hop-
pers" and hopper "values" C &
D are at zero.
