HT-R500 SERVICE MANUALSERVICE MANUAL Ref. No. 3728 042002 120V AC, 60Hz AV RECEIVER MODEL HT-R500 Black models BMDD 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 4. Memory Preservation This unit does not require memory preservation batteries. A built-in memory power back-up system preserves the contents of the memory during power failures and even when the unit is unplugged. The unit must be plugged in order to charge the back-up system. The memory preservation period after the unit has been unplugged varies depending on climate and placement of the unit. On the average, memory contents are protected over a period of a few weeks after the last time the unit has been unplugged. This period is shorter when the unit is exposed to a highly humid climate. 2. To initialize the unit This device employs a microprocessor to perform various functions and operations. If interference generated by an external power supply, radio wave, or other electrical source results in accident which causes the specified operations and functions to operate abnormally. To perform a result, please follow the procedure below. 1.Press and hold down the VIDEO-1 button, then press the STANDBY/ON button. 2.After clear is displayed, the preset memory and each mode stored in the memory, such as surround, are initialized and will return to the factory setting. 3. Safety-check out (Only U.S.A. model) After correcting the original service problem, perform the following safety check before releasing the set to the customer. Connect the insulating-resistance tester between the plug of power supply cord and screw on the back panel. Specifications: 3.3Mohm+/-10% at 500V. 1. Replacing the fuses This symbol located near the fuses indicates that the fuse used is fast 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 utlise est a rapide. Pour une protection permanente, nuntiliser que fusibles de meme type. Ce darnier est la qu le present symbol est appse. CIRCUIT NO. PART NO.
