RadioFans.CN 收音机爱 好者资料库 TX-SR803/E SERVICE PROCEDURES Worldwide models are equipped with a voltage selector to conform with local power supplies. Be sure to set this switch to match the voltage of the

15、power supply in your area before plugging in the unit. 1. Determine the proper voltage for your area: 220-240 V or 120 V. 2. If the preset voltage is not correct for your area, insert a screw- driver into the groove in the switch. Slide the switch all the way to the right (120 V) or to the left (220

16、-240 V), whichever is appropriate. 4.Setting the Voltage selector (Worldwide models only) 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

17、 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. DESCRIPTION 2. To initialize the unit This device employs a micropr

18、ocessor 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.

19、Press and hold down the VIDEO-1 button, then press the STANDBY 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. 5. Changing the AM band step With the exception of the worldwide models,

20、a tuning step selector switch is not provided. When you change the band step, change the parts as shown below. To 10kHz To 9kHz R714 Open 10 k Note: :120V model only : European model only : 230V model only :Worldwide model only : Australian model only 3. Safety-check out (U.S.A. model only) After co

21、rrecting the original service problem, perform the following safety check before releasing the set to the customer. Leakage Current Check Measure leakage current to a known earth ground(water pipe, conduit, etc.) by connecting a leakage current tester between the earth ground and exposed metal parts
