Warning This symbol means "possible to die or heavy damage"
Caution
This symbol means "possible to damage or something will break"
We made the symbol as below, which are kind of following items.
This symbol means "CAUTION"
This symbol means "POSSIBLE to
ELECTRIC SHOCK"
This symbol means "MUST"
This symbol means "DO NOT"
WARNING
Should be follows to instructions.
We indicates to cabinet, chassis and
parts by label, which are special atten-
tion part.
Please follow to note and [Safety

Prevent the electric shock.
Please take care during working
because monitor has high voltage part
and power supply part.
Possible to die if you touch to these
place by miss take.
Please disconnect power plug during
overhaul, reassemble or change parts.
You will die or take damage by electric
shock if you touch to live part.
Use recommended components.
Please use to same characteristic com-
ponent, which is same as previous for
your safety and keep reliability espe-
cially marked by in parts list and cir-
cuit diagram.
It is reason of electric shock or fire if
you use non-recommended compo-
nent.
Should be kept same style of wiring or component.
Monitor uses tubes or tapes, which
made by insulator, and some compo-
nents are keep distance from surface of
PWB for safety.
Internal leads kept from hot part or high
voltage part by clamper or styling, so
please return to original condition for
prevent to electric shock or fire.
Should be done safety check after finished.
Every part (removed screws, compo-
nent and wiring) should be returned to
previous condition.
Check around repair position for make
damage by miss take and measure the
insulated impedance by meg-ohm
meter.
Confirm the value of impedance, that
value is more than 4M ohm.
It is reason for electric shock or fire if
that value is less than 4M ohm.
Nobody can check and repair to the code
and combination circuit of HDCP.
Never remove the shield case, which is
assembled to the code and combination
circuit of HDCP.
