• High-tension Voltage
Some of the parts inside 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 interior, 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 accumulatively
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 is 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 adversely affect the human
body.
• Installation and removal
Ensure that the Demagnetizer 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 electric shock and malfunctioning.
(For the name of parts, refer to the above Figures).
