RODUCT SAFETY NOTICE
Many electrical and mechanical parts in this monitor have special safety-related characteristics.
These characteristics are often not evident from visual inspection.
Replacement parts which have these special safety characteristics are identified in this manual;
electrical components having such features identified by " ! " in the replacement parts list and
schematic diagram.
For continued protection, replacement parts must be identical to those used in the original circuit.
The use of substitute replacement parts which dose not have the same safety characteristics as the
factory recommended replacement parts shown in this service manual, may create shock, fire,
X-RAY RADIATION or other hazards.

X-Ray Radiation Precaution
1. Excessive high voltage can produce potentially hazardous X-RAY RADIATION. To avoid
such hazards, the high voltage must be under the specified limit. The nominal value of the high
voltage of this monitor is 25KV
1.0KV at zero beam current(minimun brightness) under a 120V AC
power source. The high voltage must not(under any circumstances) exceed30KV. Each time a monitor
requires servicing, the high voltage should be checked.
It is recommended the high voltage be recorded as a part of the service record. It is important to use
an accurate and reliable high voltage meter.
2. This monitor is equipped with a protection circuit which prevents the monitor from producing
excessively high voltage. Each time the monitor is serviced, the protection circuit must be checked to
determine that the circuit is properly functioning.
3. The only source of X-RAY RADIATION in this monitor is the picture-tube.
For continued X-RAY RADIATION protection, the replacement tube must be exactly the same type
tube as specified in the parts list.
4. Some parts in this monitor have special safety-related characteristics for X-RAY RADIATION
protection.
For continued safety, parts replacement should be undertaken only after referring to the product
safety notice.
PRODUCT CDRH NOTICE
Electrical potentiometers which is marked as caution " ! " in parts list are crititial components
of safety & CDRH.
Therefore, for continued protection, replacements parts must be used it which is used in original
PCB ASS’Y.
