When performing such work as installing and removing the monitor, inserting and disconnecting 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 simulta-
neously. 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 Second-
ary side. If short-circuited, it can cause electric shock or
malfunctioning, 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 malfunctioning or fire hazard.
Connecting the CRT and PCB
For combining the CRT and PCB, use the specified part No. to maintain the status of adjustments 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 malfunctioning, 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 disas-
sembled.
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.)
