PRODUCT SAFETY CAUTION
1. When parts replacement is required for servicing, always use the manufacturer's specified replacement.
2. Comply with all caution and safety-related notes on the product display chassis and picture tube.
3. When replacing the component, always be certain that all the components are put back in the place.
4. When servicing display monitor unit, it is required that the provided lead dress is used in the high voltage
circuit area.
5. It is also recommended that shatter proof goggles are worn, when removing installing and handling the
picture tube. People not equipped with the proper precautionary measures mentioned should keep the
picture tube away from body while handling.
6. As for a connector, pick and extract housing with fingers properly since a disconnection and improper
contacts may occur, when wires of the connector are led.
7. Use a proper screwdriver. If you use screwdriver that does not fit, you may damage the screws.
8. X-radiation precaution
This product contains critical electrical and mechanical parts essential for X-ray protection.
Normal anode voltage is 25.0 kV at zero beam picture tube current under AC 100-120V/220-240V input,
and anode voltage must not exceed the voltages shown below under any operation condition.
To measure anode voltage set brightness for very dim picture, and use a high impedance volt meter
between chassis and anode lead and measure high voltage.
If high voltage exceeds the specifications on the chassis schematic diagram, take the necessary
corrective action.
