  • Page 5 (ESD). Careless handling during repair can reduce life drastically. When repairing, make sure that you are connected with the same potential as the mass of the set by a wristband with resistance. Keep components and tools also at this same potential. 1.
  • Page 6 1.1.6 (1) Do not touch Signal and Power Connector while this product operates. Do not touch EMI ground part and Heat Sink of Film Filter. (2) Do not supply a voltage higher than that specified to this product. This may damage the product and may cause a fire.
  • Page 7: Notes

    (8) Do not damage or modify the power cable. It may cause fire or electric shock. (9) If the power cable is damaged, or if the connector is loose, do not use the product: otherwise, this can lead to fire or electric shock. (10) If the power connector or the connector of the power cable becomes dirty or dusty, wipe it with a dry cloth.
  • Page 8 specified. If any connection other than the one specified is made between the measuring equipment and the high voltage power supply block, it can result in electric shock or activation of the leakage-detection circuit breaker. • When installing the LCD module in, and removing it from the packing carton, be sure to have at least two persons perform the work.
  • Page 9 These wires are fixed in position with the wire clamps so that the wires do not move, thereby ensuring that they are not damaged and their materials do not deteriorate over long periods of time. Therefore, route the cables and fix the cables to the original position and states using the wire clamps.
