FIRE & SHOCK HARZARD 1) During servicing, pay attention to the original wires whether it is uncoated or undressed, especially the wires in the high voltage circuit section. If there is any uncoated or melted wire is found, then please do not try to replace the related parts, and wait for the qualified service person's coming. 2) Many electrical, mechanical parts in this monitor have special safety-related characteristics for protection against shock hazard and others. These characteristics are often passed unnoticed by a visual inspection and the protection afforded by them cannot necessarily be obtained by using replacement component rated for higher voltage wattage,etd Replacement parts which have these special characteristics are identified in the manual and supplements by shading on the schematic diagram and the parts list. 3) When replacing Chassis, always be certain that all the protective devices are installed properly. 4) leakage current check(figurel 1)
