1. The areas marked with a ! , or on the schematic diagram designate components which have special characteristics important for safety. Replace these parts only with parts identical to those in the original circuit and those specified in the parts list. Before replacing any of these components, carefully read the “Product Safety Notice.” 2. Areas marked with a on the schematic diagram designate controls which have been sealed for safety during manufacturing. If these controls need adjustment, they must be replaced with new controls and then sealed after their adjustment. 3. When taking measurements, pay special attention to the following: 1) Do not use your instrument between primary ground (symbol 2) Do not use your instrument between secondary ground (symbol ) and secondary circuit. ) and primary circuit.
1. Resistance is shown in OHM. K = 1,000, M = 1,000,000 and the rated power of resistors not noted in the schematic diagram is 1/4W.|
