Please carefully read the detail list before changing these components. 1.2.3 If the fuse is blown, please change it for the one designated in the list of components. 1.2.4 When changing resistors of 1w or bigger than 1w in PCB, make sure to separate them from the PCB by10 mm.

  • Page 5: Alignment Items And Procedure

    Points of attention for product safety There are many electric and mechanical parts in this PCB that are related to safety. However, they are often neglected from visual look. For changing the high voltage and high power parts, very often it’s impossible to provide them with effective “X-ray radiation” protection. All these exchange parts with safety characteristic are designated in the detail list.
