Safety Notices
The following safety instructions apply to all game operators and service personnel.
Specific warnings and qautions will be found throughout this manual where they
app ly .
We recommend that you read this page before preparing your game for play.
&CAUTION
AC POWER CONNECTION. Before connecting the game to the AC power
source, verify that the "line voltage selection chart" jumper wires are installed
correctly for the line voltage in your area. For details, refer to Section 3.
PROPERLY GROUND THE GAME. To avoid electrical shocks, do not plug in
the game until it has been inspected and properly grounded. MIDWAY games
should only be plugged into a grounded 3-wire outlet. Shocks will also result, if
the control panet
is not properly grounded! After servicing any partson the panel,
assure that the ground wires are secure. Only then should you lock up the game.
DISCONNECT POWER DURING REPAIRS. To avoid electrical shock, discon-
nect the game from the AC power source before removing or repairing any part of
the game.
USE THE PROPER FUSE. To avoid electrical shock, use the replacement fuse
which is specified in the parts list for this game. The replacement fuse must match
the original fuse in fuse type, voltage rating, and current rating.
MONITOR PRECAUTIONS. Wilen removing or repairing the monitor, extra pre-
cautions must be taken to avoid electrical shockbecause high voltages may exist
withinthe monitorcircuitryand cathode ray tube (CRT) even afterpowerhas been
disconnected.
Do not louch internal parts of the monitorwith your hands or metal
objects! Always discharge the CRT
by the following method: Attach one end ot
a large, well-insulated, 20-kV jumper to ground. Momentarily touch the free end
of the grounded jumperto the anode by sliding it underthe anode cap. Wait two
minutes and discharge the anode again.
•
HANDLE FLUORESCENT TUBE AND CRT WITH CARE. If you drop a
fluorescenttube orCRTand it break
s, itwill implode! Shatteredglasscanfly eight •
feet or more from the implosion.
ATTENTION!
PROPERL YA TTACH ALL CONNECTORS_ Make sure that the connectors on
each printed circuit board (PCB) are properly connected. IIfhey do not Slip on
easily, do not force them . A revers ed connector may damage your game and void
