Safety-related component warning! Components identified by mark on the schematic diagram and by mark “!” in the

4、parts list are critical for risk of fire and electrical shock. Replace these components with ONKYO parts whose part numbers appear as shown in this manual. 2. Safety check after servicing (1) To ensure safety, check that the covered insulating sheet or tube are removed, all parts and wires which are

5、 removed or disconnected while servicing have been put back to their original positions after servicing. (2) To insure structural integrity, check that all the screws or mechanical parts have been put back in their original positions after servicing. (3) Check that in the process of servicing or rep

6、lacing parts that the surrounding area has not been contaminated or adversely affected. (4) After servicing an insulation check on the external metal connectors and between the blades of the power plug must be performed. Method of checking insulation resistance Unplug the power cord and short the bo

7、th ends of the plug with a jumper wire. Using a 500V insulation resistance tester, check that the insulation resistance value between the plug of the power cord and externally exposed metal parts is 1M or greater. The mechanical power switch should be turned on if it is available. 3. Caution on repl

8、acing the battery Danger of explosion if rechargeable batteries is incorrectly replaced. Replace only with the same or equivalent type recommended by the manufacturer. When disposing of used batteries, please comply with governmental regulations or environmental public institutions rules that apply

9、in your country / area. 4. Other Cautions When AC plug is non-polarized and if Main or Primary fuse enters in the Neutral line of AC Mains supply or if there is possibility of Main or Primary Fuse entering in the Neutral line of AC Mains supply, then AC Mains supply must be disconnected to de-energi

10、ze the circuit. Be sure to use only lead free solder. When soldering, please be careful not to use too much solder and affect adjacent components. This service manual is intended for qualified service technicians; it is not meant for the casual do-it-yourselfer. Qualified technicians have the necess

11、ary test equipment and tools, and have been trained to properly and safely repair complex products such as those covered by this manual.
