*The back flange on the chute can be removed for hold position #4.
If the flange is not removed, it may interfere with the back of the
cabinent.The frame and cashbox enclosure on this coindoor has been modified to accomodate a Mars 2000 series
upstacker. A 2000 series stacker can be added by simply removing the top two entry door and replacing it with a one
entry door with a cut-out for a stacker. This one entry door can be ordered through Coin Controls or one of Coin Controls
authorized distributors. The part number is 91-4000-01. The Mars stacker can be obtained through an autherized Mars
distibutor.
It should also be noted that this unit comes equipped with security hasp that surrounds the two bottom doors where the
cash box is located. This is to ensure that the monies within are not tampered with, except by the operator.

							34 10. MONITORWhen performing such work as installing and removing the monitor, inserting and disconnect-
ing the external connectors to and from monitor, be sure to disconnect the power connector
(plug) before starting work. Proceeding the work without following this instruction can cause
electric shock of malfunctioning.
Using the monitor by converting it  without obtaining a prior permission is not allowed. SEGA
shall not be liable for any malfunctioning and accident caused by said conversion.
Primary side and secondary side
The monitor’s circuit which is divided into the Primary
side and secondary side, is electrically isolated. Do
not touch the primary side and the secondary side
simultaneously. Failing to observe the instruction can
cause electric shock, and this is very dangerous.
When making monitor adjustments, use a non-
conductive driver and make adjustment without
touching any other part other than the Adjustment
V.R. and Knob. Also, be sure not to cause a short-
circuit to the Primary side and the Secondary side. If
short-circuited, it can cause electric shock or mal-
functioning, which is very dangerous.
High tension Voltage
Some of the parts inside the monitor are subject to high-tension voltage in excess of 20,000
volts and very dangerous. Therefore, do not touch the monitor interior. Should soldering &
paper wastes, etc. be mixed in the monitor, turn the power off so as not to cause malfunc-
tioning or fire hazard.
Connecting the CRT and PCB
For combining the CRT and PCB, use the specified part No. to maintain the status of adjust-
ments made at the factory. The anode of the CRT itself will be accumulitavely charged as time
elapses, generating high tension voltage which is very dangerous. The monitor should be used
with the Chassis, CRT and PCB assembled. When repair, etc. is required at the time of malfunc-
tioning, be sure to send it in an “as assembled” condition. If these are disassembled, what’s
charged to said high tension voltage can be discharged, causing a very hazardous situation.
Therefore, under no circumstances should it be disassembled.
Static Electricity
Touching the CRT surface sometimes causes you to slightly feel electricity. This is because the
CRT surfaces are subject to static and will not adversly affect the human body.
Installation and removal
Ensure that the Magnetizer Coil, FBT (Fly-Back Transformer), Anode Lead and Focus Lead are
not positioned close to the sheet metal work’s sharp edges, etc. and avoid damaging the
insulated portions so as not to cause an electric shock and malfunctioning. (For the name of
parts, refer to the above figures.) 
						

							35For the purpose of static prevention,
special coating is applied to the CRT
face of this product. To protect the
coating, pay attention to the following
points. Damaging the coating film can
cause electric shock to the customers.
For the caution to be heeded  when
clearing, refer to the Section of Periodic
inspection Table.
Do not apply or rub with a hard item (a
rod with pointed edge, pen, etc.) to or
on C.R.T. surfaces.
Avoid applying stickers, seals, etc. on
the C.R.T. face.
Do not remove aluminum foils from the
C.R.T. corners. Removing the aluminum
foils can cause static prevention effects
to be lowered.Monitor adjustments have been made at the time of shipment. There-
fore do not make further adjustment without a justifiable reason.
Adjusting the monitor which contains high tension parts is dangerous
work. Also, an erroneous adjustment can cause deviated synchroniza-
tion and image fault, resulting in malfunctioning.
When making adjustment, utilize a resinous Alignment Rod. Servicing
with bare hands or using conductive tools can cause electric shock. 
						

							36When performing such work as monitor installation/removal, or inserting /disconnectiing the
exteernal Connector connected to teh monitor and it’s interiror, first be sure to disconect thje
power connector (plug). Working witht eh power plug as is connected can cause electric shock or
malfunctioning.
When performing work, be very careful. To avoid electric shock accidents, etc., personnel other
tha those who have technical expertise are not allowed to perform this work.
Perform work bny following the procedure herein stated. Failing to comply with these instructions
can cause an electric shock accident.
Be sure to use 2 or more workers for this work. Performing work by work person can cause injury
or parts damage.
To ensure performing the work safety, provide sufficient space.
Working in  places with narrow space can cause injury or working errors.
Be careful so as not to damage wirings. Damaged wiring can cuase an electric shock or short
circuit accident.
Do not touch places ther than those specified. Touching places other than those specified can
cuase an electric shock or short circuit accident.After the vertical/horizontal transposition of the MONITOR (GAME BD
replacement), monitor adjustments may be required.For perfroming the monitor’s vertical/horzontal transposition in the manner consistent with the Game Board, follow the
procedure below:
After turning power off by using the Main SW of
AC Unit or the SUB PWR SPLY SW inside the
SERVICE DOOR, unplug the power plug from the
socket outlet.
