(3) Essential safety critical components are identified by ( ) on the Parts List and by shading on the schematics, and must never be replaced by parts other than those listed in the manual. Please note however that many electrical and mechanical parts in the product have special safety related characteristics. These characteristics are often not evident from visual inspection. Parts other than specified by the manufacturer may not have the same safety characteristics as the recommended replacement parts shown in the Parts List of the Service Manual and may create shock, fire, or other hazards. (4) The leads in the products are routed and dressed with ties, clamps, tubings, barriers and the like to be separated from live parts, high temperature parts, moving parts and/or sharp edges for the prevention of electric shock and fire hazard. When service is required, the original lead routing and dress should be observed, and it should be confirmed that they have been returned to normal, after re-assembling. 1.5.1Warning (1) Service should be performed by qualified personnel only. (2) This equipment has been designed and manufactured to meet international safety standards. (3) It is the legal responsibility of the repairer to ensure that these safety standards are maintained. (4) Repairs must be made in accordance with the relevant safety standards. (5) It is essential that safety critical components are replaced by approved parts. (6) If mains voltage selector is provided, check setting for local voltage. Burrs formed during molding may be left over on some parts of the chassis. Therefore, pay attention to such burrs in the case of preforming repair of this system.
