HT-RC260 SERVICE MANUAL AV RECIEVER Black model MODEL HT-RC260 (B) 120V AC, 60HzBMDC Ref. No. 4194 042010 RC-764M SAFETY-RELATED COMPONENT WARNING! COMPONENTS IDENTIFIED BY MARK ON THE SCHEMATIC DIAGRAM AND IN THE PARTS LIST ARE CRITICAL FOR RISK OF FIRE AND ELECTRIC SHOCK. REPLACE THESE COMPONENTS WITH ONKYO PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL. MAKE LEAKAGE-CURRENT OR RESISTANCE MEASUREMENTS TO DETERMINE THAT EXPOSED PARTS ARE ACCEPTABLY INSULATED FROM THE SUPPLY CIRCUIT BEFORE RETURNING THE APPLIANCE TO THE CUSTOMER. RadioFans.CN 收音机爱 好者资料库 SERVICE PROCEDURE HT-RC260 1. Replacing the fuses This symbol located near the fuse indicates that the fuse used is show operating type, For continued protection against fire hazard, replace with same type fuse, For fuse rating, refer to the marking adjacent to the symbol. Ce symbole indique que le fusible utilise est e lent. Pour une protection permanente, nutiliser que des fusibles de meme type. Ce demier est indique la qu le present symbol est apposre. 2. To initialize the unit 1. Press and hold down VCR/DVRbutton, then press ON/STANDBY button when the unit is powered on. 2. After Clear is displayed, the preset memory and each mode stored in the memory are initialized and will return to the factory settings, and turn to Standby mode. 3. Safety check out REF No. PART NAMEDESCRIPTIONPART N O.REMARKS Canadian model : (U.S.A. model only) After correcting the original service problem, perform the following safety check before releasing the unit to the customer. Leakage current Check Measure the leakage current to a known earth ground (water pipe or conduct etc.) by connecting a leakage current tester between the earth ground and exposed metal parts of the unit (input/output ground terminals, screw heads or metal overlays etc.). Plug the power supply cord directly into a 120Vac 60Hz wall socket and turnON/STANDBY button on. Any current measured must not exceed 0.5mA. This model uses a EE-PROM IC in order to retain radio presets and other settings. So, memory contents will be kept eternally with no care. 4. Memory Backup 3. Remove the AC cord from power line.
