Tetris
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.
ABOUT NOTES, CAUTIONS,
