overhead display)

of one
machine to

Check that there is only one
‘MASTER MACHINE’
(This is
ALWAYS
the
Overhead Jackpot Display), and
ALL
the game machines are
‘SLAVE
MACHINES’
. (Program adjustment P01).

By checking what the displays show on
‘POWER UP’;
can help diagnose where
a break or bad connection in the link could be. Refer to diagram below:
* NOTE:
If, is displayed on more than one machine it means that
there is more than
ONE
‘MASTER’

machine that is automatically the Overhead Jackpot display. Change any other
games displaying Er4 to ‘
SLAVE”
