Be sure to set this switch to match the

15、 voltage of the 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 upper (120 V) or

16、to the down side (220-240 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

17、 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. DESCRIPTION 2. To initialize the unit This dev

18、ice 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 th

19、e procedure below. 1.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 t

20、he worldwide models, a tuning step selector switch is not provided. When you change the band step, change the parts as shown below.

Safety-check out (U.S.A. model only) After correcting the original service

22、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 of the appliance (input/outpu

23、t terminals, screwheads,metal overlays, etc.). Plug the power supply cord directly into a 120V AC 60 Hz outlet and turn Standby switch on. Any current meausred must not exceed 0.5mA.
