Safety Summary
The following safety precautions apply to all game op-
erators and service personneL Specific warnings and
cautions will be found in this manual whenever they
apply.
WARNING
Properly Ground the Game. Players may receive an
electrical shock if this game is not properly grounded!
To avoid electrical shock, do not plug in the game un-
til it has been inspected and properly grounded. This
game should only be plugged into a grounded three-
wire outlet. If you have only a two-wire outlet, we rec-
ommend you hire a licensed electrician to install a
three-wire grounded outlet. If the control panel is not
properly grounded, players may receive an electrical
shock! After servicing any part on the control panel,
check that the grounding wire is firmly secured to the
inside of the control panel. After you have checked
this, lock up the game.
AC Power Connection. Before you plug in the game,
be sure that the game's power supply can accept the
AC line voltage in your location. The line voltage re-
quirements are listed in the first chapter of this man-
ual.
Disconnect Power During Repairs. To avoid electri-
cal shock, disconnect the game from the AC power be-
fore removing or repairing any part of the game. If
you remove or repair the video display, be very care-
ful to avoid electrical shock. High voltages continue to
exist even after power is disconnected in the display
circuitry and the cathode-ray tube (CRn. Do not touch
the internal parts of the display with your hands or
with metal objects! Always discharge the high voltage
from the CRT before servicing it. Do this after you dis-
connect it from the power source. First, attach one end
iv
of a large, well-insulated, IS-gauge
jumper wire to ground. Then
momentarily touch the free
end of the grounded
jumper wire to the CRT
anode by sliding the
wire under the anode
cap. Wait two minutes
and do this again.
Use Only Atari Parts. To maintain the safety of your
Atari game, use only Atari parts when you repair it.
Using non-Atari parts or modifying the game circuitry
may be dangerous, and could injure you and your
players.
Handle the CRT With Care. If you drop the CRT and
it breaks, it may implode! Shattered glass from the im-
plosion can fly six feet or more.
Use the Proper Fuses. To avoid electrical shock, use
replacement fuses which are specified for your original
game. Replacement fuses must match those replaced
in fuse type, voltage rating, and current rating.
CAUTION
Properly Attach All Connectors. Make sure that the
connectors on each printed circuit board (PCB) are
properly plugged in. The connectors are keyed to fit
only one way. If they do not slip on easily, do not
force them. If you reverse a connector,
it
may damage
your game and void your warranty.
Ensure the Proper AC Line Frequency. Video
games manufactured for operation on 60 Hz line pow-
er (used in the United States) must not be operated in
countries with 50 Hz line power (used in Europe). If a
60 Hz machine operates on 50 Hz line power, the fluo-
rescent line ballast transformer will overheat and cause
a potential fire hazard. Check the product identifica-
tion label on your machine for the line frequency re-
quired.
